Gut Helminths | Threadworms

Welcome to sqadia.com, where we are covering subject-specific topics. We have landed on Microbiology, and you will be seeing more subjects on sqadia.com, so stick around.

Today, we will be talking about Gut Helminths in detail. Where, we will cover Helminth's pathogenesis, common helminths in the gut that cause diseases, helminth types, and helminths' life cycle in detail. So, let’s jump in!

▬ 📌 Gut Helminths
Helminths parasites are the most common pathogenic parasites infecting humans. If we have a look at the Helminths classification, it includes:
🟡 Hookworm
🟡 Roundworm
🟡 Threadworm
🟡 Strongyloides Stercolaris
🟡 Tapeworm

▬ 📌 Hookworm
Ancylostoma duodenale are the most common hookworms. Humans are infected with moist soil. Major damage is due to loss of blood. Hookworm is found worldwide, especially in tropical areas. Walking barefooted on soil predisposes to infection. An important public health measure was requiring children to wear shoes to school. To diagnose an infection caused by hookworm, it is very important to know the accurate diagnostic criteria.
🟠 Diagnosis is made microscopically by observing the eggs in the stools
🟠 Occult blood in the stools is frequent
🟠 Eosinophilia is typical

The pharmacological treatment for hookworm infection involves the use of two drugs.
🟢 Mebendazole
🟢 Pyrantel pamoate

Not only this, but learn about the pathogenesis and helminth lifecycle of hookworm in the video.

▬ 📌 Roundworm
The most important species of roundworm is Ascaris lumbricoides which causes a disease known as ascariasis. Roundworm causes ascariasis.

Now, what are some of the important properties of each roundworm?
🔵 Humans are infected
🔵 Egg hatches in intestine
🔵 Lumbricoides are giant roundworms

Most infections are asymptomatic. Ascaris pneumonia with fever, Cough, and eosinophilia can occur with a heavy larval burden. Abdominal pain and even obstruction can result from the presence of adult worms in the intestine.

👉 Eosinophilia is typical
The pharmacological treatment for hookworm infection involves the use of two drugs.
⚫️ Mebendazole
⚫️ Pyrantel pamoate

▬ 📌 Threadworms (Pinworms)
Threadworm also known as pinworm consists of an important specie called Enterobius vermicularis which causes pinworm infection also known as enterobiasis.

Now, what are some of the important properties of each Pinworm species?
🟤 Infection occurs only in humans
🟤 Egg hatches in small intestine
🟤 Embryonated eggs develop and become infectious

👉 Strongyloides Stercolaris
Strongyloides stercoralis are human parasitic gut helminths that cause strongyloidiasis.

Now, important points you need to know about Strongyloides stercolaris are:
🟣 Penetration in the skin
🟣 Egg hatches in intestine
🟣 Filariform larvae

▬ 📌 Tapeworm
There are two important human pathogens in the genus Taenia: T. solium--the pork tapeworm and T. saginata--the beef tapeworm. The adult form of T. solium causes taeniasis.

Now, what are some of the important properties of each species?
🟠 Four suckers
🟠 Tapeworms are present in the small intestine
🟠 Oncospheres

These were just the highlights. You still need to watch the video to learn about these helminth's lifecycle, pathogenesis, treatment, prevention, and much more.

So, Watch the complete video to dive deeper into the details of Gut helminth parasites.
