Dientamoebiasis is an intestinal infection that can cause stomach pain, loose stools, bloating, and nausea, although some people have no symptoms. It can affect children and adults, and early symptoms of Dientamoebiasis may come and go for days or weeks. Dientamoebiasis is usually not life-threatening, but ongoing diarrhea can lead to dehydration, especially in young children and older adults. Not everyone will have the same experience. Treatment often includes prescription antiparasitic medicine, fluids, and follow-up with a doctor if symptoms continue.
How many people live with Dientamoebiasis?
There is no single reliable estimate of how many people live with dientamoebiasis worldwide or in the United States, because this gut infection is not routinely counted and study results change a lot depending on the stool test used and whether people had symptoms. Reported rates vary widely from one study to another, so a firm global total and a firm U.S. total are not available.
Overview
DientamoebiasisSymptoms
Dientamoebiasis often causes diarrhea, stomach cramps, bloating, nausea, and tiredness. Some people also have loose stools that come and go, which can make the early symptoms of dientamoebiasis easy to miss.
Outlook and prognosis
Most people with Dientamoebiasis improve fully, especially when the infection is found and treated. Stomach pain, loose stools, and bloating usually settle over days to weeks, though some people have symptoms longer or can get infected again.
Causes and risk factors
Dientamoebiasis usually happens after swallowing tiny parasite particles through contaminated food, water, or unwashed hands. Risk rises with close household or childcare contact, poor sanitation, travel, and crowded living conditions. Weakened immunity may raise the chance of ongoing symptoms.
Genetic influences
Genetics are not a main cause of dientamoebiasis, because it is usually linked to infection and exposure. Still, small genetic differences may affect how strongly some people react or how likely symptoms are.
Diagnosis
Dientamoebiasis is usually diagnosed with stool testing to look for the parasite or its genetic material. Because it can be missed on a single sample, diagnosis of Dientamoebiasis may require more than one stool sample.
Treatment and drugs
Dientamoebiasis is usually treated with prescription antiparasitic antibiotics such as paromomycin, metronidazole, or iodoquinol. Many people improve within days, and follow-up stool testing may be needed if symptoms return or continue.
Symptoms
Dientamoebiasis often shows up as an unsettled stomach that comes and goes, making meals, school, or work harder to get through. Some people notice early symptoms of Dientamoebiasis such as loose stools, cramping, bloating, or nausea, while others have no symptoms at all. Symptoms vary from person to person and can change over time.
Loose or frequent stools are one of the most common symptoms of Dientamoebiasis. The pattern can be steady for some people or come and go over days to weeks.
Cramping or aching in the abdomen is common and may feel worse before using the bathroom. For many people with Dientamoebiasis, this can make eating, commuting, or sleeping less comfortable.
A swollen, gassy feeling in the belly can happen even when bowel movements are not very frequent. Some may find that clothes feel tighter or meals leave them uncomfortably full.
Some people with Dientamoebiasis feel queasy, especially around meals or when stomach cramps flare up. This does not always lead to vomiting, but it can make it harder to eat normally.
How people usually first notice Dientamoebiasis?
People usually first notice dientamoebiasis when stomach trouble does not settle down, especially loose stools or diarrhea, cramping belly pain, bloating, nausea, or needing to use the bathroom more often than usual. For many, the first signs of dientamoebiasis can be mild and easy to brush off at first, but if symptoms linger for days or keep coming back, some may also notice tiredness, loss of appetite, or unplanned weight loss. Not everyone feels very sick, which is one reason this infection can be missed early, but ongoing gut symptoms are a common clue that it is time to check in with a clinician.
Types of Dientamoebiasis
Dientamoebiasis can range from causing no noticeable problems to ongoing bowel symptoms that come and go. Symptoms don’t always look the same for everyone. There are no formal disease subtypes, so when people talk about types of Dientamoebiasis, they usually mean these common patterns of symptoms and how long they last.
No symptoms
Some people with Dientamoebiasis feel completely well and only learn about the infection after stool testing. Even without symptoms, the parasite can still be present in the gut.
Short-term digestive
This pattern often causes loose stools, stomach cramps, bloating, nausea, or a general upset stomach over days to weeks. Some may also notice fatigue or a reduced appetite, but symptoms can stay fairly mild.
Long-lasting digestive
Many living with Dientamoebiasis have symptoms that keep returning or linger for weeks to months, sometimes looking a lot like irritable bowel symptoms. Belly pain, diarrhea, urgency, and bloating may flare on some days and ease on others.
Can I slow down the onset of symptoms?
No—there is no good evidence that lifestyle changes or medicines can meaningfully delay the start of symptoms in dientamoebiasis once this gut infection is already in the body. What may help is lowering the chance of getting infected in the first place: careful handwashing, safer food handling, and avoiding contact with stool are linked to lower risk, but reducing risk is not the same as preventing the infection. There is no routine preventive medicine for most people, but early testing and treatment if symptoms begin can help, and simple hygiene steps are still worth taking even though they cannot guarantee you will stay well.
What genetics can tell you about symptoms
At this time, genetics cannot reliably predict which symptoms someone with dientamoebiasis will have, how severe they will be, or when they will start. Some people have no symptoms at all, while others develop ongoing belly pain, loose stools, bloating, or tiredness, and this variation seems to depend more on factors like age, gut health, other infections, and the body’s immune response than on known inherited gene changes. Researchers are still studying whether small genetic differences in the parasite or in a person’s immune system play a part, but there is no well-established genetic test used in routine care for this.
Causes and risk factors
People often ask how you get dientamoebiasis, and it usually starts when the parasite Dientamoeba fragilis gets into the gut through tiny amounts of infected stool on hands, surfaces, food, or water. Risk is higher in young children and in people who live or work in close-contact settings like day care centers. It is rarely just one factor, and the mix often matters. Poor handwashing, limited sanitation, travel, and close contact with someone who has the infection or pinworms can all raise the chance of getting dientamoebiasis. There are no well-established inherited genetic risk factors for dientamoebiasis, but age, gut health, and immune status may affect whether symptoms appear.
What are the most common causes or risk factors?
Dientamoebiasis is caused by a tiny parasite getting into the gut, usually when small traces of stool are accidentally swallowed from unwashed hands, contaminated food or water, or shared surfaces. The biggest risk factors are poor handwashing, close contact with someone who is infected, and places where germs spread easily, such as day care centers, crowded homes, or areas with poor sanitation. Children, people living with an infected person, and those traveling to places with less reliable sanitation may be more likely to get it.
Environmental and biological risk factors
Dientamoebiasis is an intestinal infection linked mainly to how easily the parasite can move between people in shared environments. The main risk factors for dientamoebiasis involve exposure to tiny amounts of stool carrying the parasite, especially in places where people live, learn, or receive care close together. Doctors often group risks into internal (biological) and external (environmental).
Living with someone who has dientamoebiasis can raise the chance of exposure. Shared bathrooms, diaper-changing areas, and close day-to-day contact can make spread more likely.
Daycare centers, schools, and other group-care settings can make transmission easier. When many people share toilets, sinks, and surfaces, small amounts of contamination can pass from one person to another.
Risk is higher where toilet facilities, wastewater disposal, or cleaning systems are poor. This can allow stool contamination to reach hands, surfaces, and food-preparation areas.
Living in or traveling to places where intestinal parasites are more common may increase the risk of dientamoebiasis. This is often linked to broader sanitation and public health conditions in the area.
Genetic risk factors
If you are wondering about genetic risk factors for Dientamoebiasis, none have been clearly proven so far. Dientamoebiasis is not known to be an inherited condition, and no specific gene changes have been confirmed as a cause. Research on why some people get symptoms and others do not is still limited. At this point, doctors do not use family history or genetic testing to predict risk in any routine way.
No inherited cause: Dientamoebiasis is not known to come from a gene change passed down through a family. Current research does not support any single inherited mutation as a cause.
Family history: A family history of Dientamoebiasis has not been shown to be a reliable sign of inherited risk. Genetics has not been proven to explain who develops this infection.
Immune genes: Researchers have not identified a specific immune-system gene that clearly raises the chance of Dientamoebiasis. People may respond differently to infection, but no genetic marker is used in routine care to predict who will become ill.
Lifestyle risk factors
Dientamoebiasis is usually linked to behaviors that increase fecal-oral spread rather than to inherited traits. The main lifestyle risk factors involve hand hygiene, food handling, sanitation habits, and certain sexual practices. When people ask about lifestyle risk factors for Dientamoebiasis, the focus is on daily habits that make intestinal infection more or less likely.
Not washing hands well after using the toilet or before eating can make it easier to swallow Dientamoeba fragilis from contaminated fingers. This raises the chance of developing diarrhea, abdominal pain, and ongoing gut symptoms.
Eating food prepared with unclean hands or poor kitchen hygiene can increase the chance of ingesting the parasite. Inadequate washing of raw produce can also contribute when contamination is present.
Drinking untreated water or using it to wash foods can increase exposure if sanitation is poor. This is especially relevant during travel or in settings where water safety is uncertain.
Living in crowded households or caregiving settings can raise risk when toilet hygiene, diaper changing, and hand cleaning are inconsistent. The infection can spread more easily from person to person in these situations.
Risk prevention
Dientamoebiasis is usually reduced by lowering exposure to germs that spread through stool, especially in settings where hand hygiene or food safety is harder to maintain. The most practical steps are careful handwashing, safer food and water habits, and avoiding close contact with possible sources of infection. Prevention is about lowering risk, not eliminating it completely. If you have ongoing diarrhea, stomach cramps, or other possible early symptoms of dientamoebiasis, getting checked can also help prevent spread to others.
Wash your hands well with soap and water after using the bathroom, changing diapers, and before eating or preparing food. This is one of the most effective ways to lower the risk of dientamoebiasis.
Wash produce, cook food thoroughly, and avoid food prepared in unclean conditions. These steps can reduce the chance of swallowing the parasite that causes dientamoebiasis.
Drink safe, treated water when sanitation is uncertain, and use safe water for brushing teeth or washing foods. This matters most during travel or in places where water may be contaminated.
Clean toilets, bathroom surfaces, and diaper-changing areas regularly, especially if someone at home has diarrhea. Good household hygiene can help stop germs from spreading from one person to another.
Can you prevent Dientamoebiasis?
You cannot always fully prevent dientamoebiasis, because experts do not yet understand every way it spreads. The best-known steps are careful handwashing after using the bathroom or changing diapers and before eating or preparing food, along with safer food and water habits, especially when traveling. These steps can lower the risk, but they cannot guarantee you will not get the infection.
Transmission
Dientamoebiasis is usually thought to spread when tiny amounts of stool from an infected person get into someone else's mouth, most often through unwashed hands, diaper changes, shared bathrooms, or contaminated food or water. If you are wondering how dientamoebiasis spreads from person to person, the clearest answer is that close contact and poor hand hygiene seem to matter most, although the exact route is still not fully understood.
Many people with dientamoebiasis do not pass it on easily in everyday casual contact, so it is not usually considered highly contagious in the way stomach viruses can be. Still, it can spread within households, child care settings, or other places where handwashing and sanitation are harder to keep up with.
When to test your genes
For dientamoebiasis, genetic testing of your own genes is not used for early detection or to tailor treatment. If symptoms such as ongoing diarrhea, cramps, or bloating raise concern, the useful tests are stool studies, sometimes including PCR, which looks for the parasite’s genetic material.
Diagnosis
Dientamoebiasis is usually diagnosed when ongoing stomach upset, loose stools, cramping, or bloating lead someone to seek care. Doctors usually begin with your symptoms, travel and exposure history, and a stool test, because the germ can be easy to miss on a single sample. In the diagnosis of Dientamoebiasis, results sometimes take more than one step to confirm, especially when symptoms overlap with other bowel infections or irritable bowel syndrome.
Your clinician asks about diarrhea, belly pain, nausea, weight loss, recent travel, childcare exposure, and close contacts with similar symptoms. A careful history helps decide how likely Dientamoebiasis is and which stool tests are most useful.
The exam looks for signs of dehydration, abdominal tenderness, and how much the illness is affecting day-to-day life. Physical findings are often mild or nonspecific, so the exam mainly helps rule out more urgent causes.
Stool samples are examined for the parasite under a microscope, often using special stains that make it easier to see. More than one sample on different days is commonly needed because the organism may not appear in every specimen.
Some labs use molecular stool tests such as PCR, which can detect the parasite more sensitively than routine microscopy. This can be especially helpful when early stool exams are negative but symptoms still suggest Dientamoebiasis.
How is Dientamoebiasis diagnosed?
Dientamoebiasis is usually diagnosed by testing stool samples to look for the parasite that causes the infection. Because it can be easy to miss, doctors may ask for more than one sample and may use a more sensitive lab test that looks for the parasite's genetic material, not just a microscope exam. Symptoms like diarrhea, stomach pain, or bloating can point to it, but symptoms alone are not enough to confirm the diagnosis.
Stages of Dientamoebiasis
Dientamoebiasis does not have defined progression stages. This is because it is usually an intestinal infection that may cause symptoms like stomach pain, loose stools, bloating, or come and go over time, rather than moving through clear step-by-step phases. Doctors usually start with a conversation about symptoms such as ongoing diarrhea, belly cramps, and other early symptoms of dientamoebiasis, along with possible exposure risks. Diagnosis is usually made with stool testing, and sometimes repeat samples are needed because the parasite can be missed on a single test.
Outlook and prognosis
The outlook for people with dientamoebiasis is generally very good, especially when the infection is recognized and treated appropriately. Many people recover fully with antiparasitic therapy, and even some untreated cases may resolve on their own, although symptoms can persist or recur in others. Prognosis is best in otherwise healthy individuals, while prolonged diarrhea or abdominal pain can lead to dehydration, weight loss, or reduced quality of life if the illness is not addressed. Severe complications are uncommon, and current evidence suggests that death from dientamoebiasis is exceedingly rare. Relapse or reinfection can occur, particularly if household or environmental sources are not identified, so follow-up may be needed when symptoms continue.
Long-term effects
For many people, dientamoebiasis is short-lived or improves after treatment, but some can have symptoms that come and go for weeks or months. The long-term picture is often ongoing gut upset rather than permanent damage. In a smaller group, symptoms can linger, especially if the infection is not recognized early or returns after treatment. Serious lasting complications from dientamoebiasis are considered uncommon.
Some people with dientamoebiasis have loose stools that keep returning over time. This can interfere with work, school, travel, and daily routines, especially when bathroom access feels uncertain.
Cramping, bloating, and stomach discomfort may continue between more obvious flare-ups. For many, symptoms build after meals or appear in waves, which can make the early symptoms of dientamoebiasis easy to mistake for another gut problem.
Ongoing nausea, abdominal discomfort, or frequent stools can make eating feel less appealing. Over time, this may lead to mild weight loss or low energy, particularly in children or in people who have had symptoms for a long time.
Symptoms can improve and then come back, sometimes because the infection was not fully cleared or because of reinfection. This stop-and-start pattern can delay diagnosis and extend the overall course of dientamoebiasis.
How is it to live with Dientamoebiasis?
Living with dientamoebiasis can be frustrating because symptoms often come and go, and many people deal with cramping, loose stools, bloating, fatigue, or nausea that can disrupt work, school, travel, and meals out. Some people have only mild symptoms, while others find that the uncertainty of when their stomach will flare is the hardest part of daily life. For people around you, the main impact is usually practical rather than dramatic, with shared concerns about bathroom access, missed plans, and careful hand hygiene, since good hygiene helps reduce the chance of spreading intestinal infections in general.
Treatment and drugs
Dientamoebiasis is treated based on symptoms, how long they have lasted, and whether testing shows the parasite is still present. Some people with mild illness get better without specific medicine, while others need an antibiotic to clear the infection, especially if diarrhea, stomach cramps, nausea, or ongoing bowel changes are disrupting daily life. Doctors may also recommend fluids and simple measures to prevent dehydration, which can matter if frequent loose stools make it hard to work, study, or get through the day comfortably. Not every treatment works the same way for every person, so if symptoms continue after treatment, your doctor may repeat testing, consider another medicine, and check for other causes of gut symptoms. Good handwashing and avoiding spread within the household are also part of care, since early symptoms of Dientamoebiasis can look like many other stomach bugs.
Can you cure Dientamoebiasis?
Yes. This gut infection caused by a tiny parasite can often be cured with prescription medicine, although some people with mild symptoms get better on their own. Treatment is meant to clear the parasite and ease problems like diarrhea, stomach pain, and bloating, but if symptoms do not go away, a doctor may need to check for another cause or test again.
Non-drug treatment
Dientamoebiasis can make everyday life uncomfortable, with loose stools, cramps, and urgency that may make it hard to work, travel, or eat normally. Non-drug treatments for dientamoebiasis focus on replacing lost fluids, easing stomach upset, and lowering the chance of passing the infection to others. Beyond prescriptions, supportive therapies can help you feel steadier while your medical team decides whether parasite-specific medicine is needed. For many living with dientamoebiasis, careful hygiene and food safety are just as important as symptom relief.
Drinking plenty of water, broth, or oral rehydration solution helps replace fluid and salts lost through diarrhea. This is especially important if dientamoebiasis causes frequent stools, dizziness, dry mouth, or low urine output.
Small, simple meals can be easier on the gut when cramps or nausea make eating feel difficult. Many people with dientamoebiasis do better for a short time with bland foods and by avoiding alcohol, very fatty meals, and heavily spiced dishes if these seem to worsen symptoms.
Careful hand washing with soap and water after using the bathroom and before eating can reduce spread within the home. This matters because home care for dientamoebiasis includes preventing repeat exposure from contaminated hands and surfaces.
Cleaning toilet seats, flush handles, faucets, and other high-touch bathroom surfaces can help limit transmission. It also helps to avoid sharing towels and to wash underwear, bed linens, or soiled clothing promptly.
Your genes may have an impact on how drugs work for you
For people with dientamoebiasis, there is no well-established evidence that inherited genetic differences strongly change how the usual medicines work, so genetic testing is not a routine part of care for this infection. In everyday practice, treatment response is much more often affected by things like which medicine is chosen, the dose, side effects, age, pregnancy, liver health, and whether the parasite is truly the cause of the stomach symptoms. If symptoms do not improve, the next step is usually to review the diagnosis and treatment plan rather than to look for a genetic reason.
Pharmacological treatments
Stomach cramps, loose stools, and bloating from Dientamoebiasis can make work, school, and meals feel harder than they should. Treatment usually focuses on antibiotics that clear the parasite from the gut, with the choice depending on age, symptoms, local practice, and what medicines are available. Not everyone responds to the same medication in the same way. In people with ongoing diarrhea or other early symptoms of Dientamoebiasis, doctors may also look for other gut infections before deciding on treatment.
Paromomycin is often a preferred treatment for Dientamoebiasis because it stays mostly in the intestines, where the parasite lives. It can be effective at clearing the infection and may cause stomach upset, nausea, or cramping in some people.
Metronidazole is another commonly used antibiotic for Dientamoebiasis, especially when symptoms are more troublesome or paromomycin is not suitable. It can cause nausea, a metallic taste, and poor tolerance with alcohol, so people are usually advised to avoid drinking alcohol during treatment and for a short time after.
Tinidazole and secnidazole are related medicines that may be used in some settings because they can be easier to take than metronidazole. They are not used everywhere, and side effects can include nausea, stomach discomfort, and a metallic taste.
Tetracycline or doxycycline may sometimes be used for Dientamoebiasis, mainly when other standard options are not available or have not worked well. These drugs are not right for everyone, including many young children and some pregnant people, because they can affect teeth and bone development.
Genetic influences
If several people in one home develop stomach cramps, bloating, or loose stools around the same time, it can be easy to wonder whether dientamoebiasis runs in the family. It’s natural to ask whether family history plays a role. In most cases, though, dientamoebiasis is not an inherited condition; it is an intestinal infection, so shared exposure, close contact, or living conditions matter much more than genes. If more than one relative has it, that usually points to the same source of infection rather than a gene passed down from parent to child. Researchers are still studying whether small differences in immune response may help explain why some people have early symptoms of dientamoebiasis while others have no symptoms at all, but this is not something doctors test for in routine care. For now, genetics is not considered a main driver of dientamoebiasis, and there is no known gene change that causes it.
Is Dientamoebiasis genetic?
Genetics are not a main cause of dientamoebiasis, because it is usually linked to infection and exposure. Still, small genetic differences may affect how strongly some people react or how likely symptoms are.
Having a genetic risk is not necessarily a diagnosis
Genetic variants are common and are a normal part of being human. Most do not directly affect health and simply reflect natural differences among people. For many genes, having a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors are involved. In some situations, though, one well-characterized variant in a specific gene is enough to establish a diagnosis.
Pharmacogenetics—how genetics influence drug effects
When doctors choose the best treatment for Dientamoebiasis, they usually focus on symptoms, stool test results, age, pregnancy, and other medicines you take rather than on genetic testing. Medicines used for Dientamoebiasis, including options such as paromomycin or metronidazole, are not usually selected based on your genes because clear, well-proven drug-gene rules are not part of standard care for this infection. Not every difference in response is genetic, but inherited differences in how the body handles medicines may sometimes play a small part in side effects or how well a drug is tolerated. So if one family member feels better quickly while another has nausea, stomach upset, or needs a different drug, the reason is often a mix of the medicine itself, other health conditions, and whether the parasite has fully cleared. If treatment for Dientamoebiasis does not seem to work, doctors usually first check for ongoing infection, reinfection, or whether a different medication would be a better fit, rather than ordering pharmacogenetic testing.
Interactions with other conditions
Dientamoebiasis can be harder to sort out when it happens alongside other stomach or bowel problems, because symptoms like belly pain, loose stools, bloating, and tiredness can overlap. Someone might notice their symptoms flare when another condition is active. For example, people with irritable bowel syndrome, inflammatory bowel disease, or another gut infection may find it less clear whether Dientamoebiasis is the main cause of a bad spell or one part of a bigger picture. This matters because the early symptoms of Dientamoebiasis can look a lot like other common digestive illnesses, and treatment choices may differ depending on what else is going on. In some cases, ongoing diarrhea from Dientamoebiasis can also worsen dehydration or make it harder to manage other health issues, especially in children, older adults, or people whose immune system is weakened. If symptoms are persistent or seem out of proportion, doctors may look for other infections or bowel conditions at the same time rather than assuming there is only one cause.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Dientamoebiasis?
Dientamoebiasis can look a lot like other causes of diarrhea, stomach cramps, bloating, and nausea, especially giardia infection, other gut parasites, a stomach bug, or food poisoning from bacteria. If symptoms keep coming back or last for weeks, doctors may also consider irritable bowel syndrome and bowel inflammation such as Crohn's disease or ulcerative colitis.
History
Dientamoebiasis came to medical attention in the early 1900s, when doctors began noticing a tiny parasite in stool samples from people with ongoing stomach problems. At first, it was easy to miss. In recent decades, awareness has grown as better lab methods have shown that this organism may be linked with diarrhea, belly pain, bloating, and other digestive symptoms in at least some people.
The parasite behind dientamoebiasis was first described in 1918, but for many years experts were unsure how important it really was. Some early reports suggested it might simply live in the gut without causing harm, while others described people who felt unwell for weeks or months, with symptoms that could come and go. This uncertainty meant that many living with unexplained digestive trouble may not have been tested for it, especially when symptoms looked similar to irritable bowel syndrome or a short-term stomach infection.
As laboratory science improved, the picture became clearer. Standard stool microscopy often missed the parasite, so older studies probably underestimated how common dientamoebiasis was. Newer testing methods, including more sensitive stool tests, helped doctors recognize it more often and study it more carefully. That has been especially useful for people with persistent loose stools, cramping, or discomfort after other common causes have been ruled out.
Today, dientamoebiasis is better understood than it was a century ago, though some questions remain about why it causes symptoms in some people but not others. What has changed most is practical: clinicians now know to consider it when someone has ongoing digestive symptoms, and modern testing has made diagnosis much more reliable. For many, this history helps explain why early symptoms of dientamoebiasis were once overlooked or attributed to other gut conditions.
