Trichuriosis , also called endemic nematodes, is a disease of the digestive tract caused by Trichuris trichiura . He belongs to the nematodes. It is a human and primate parasite widespread mainly in the tropics and subtropics. That is why most diseases are imported in our country. The prevalence of the disease is 800-1300 million. The morbidity is 0.2%.
The course of infection
Contamination occurs mainly orally - by ingesting contaminated food or drink. The larvae hatch and live in the crypts of the small intestine. Adults then migrate to the large intestine, mainly the cecum. There, the anterior thin part is immersed in the mucosa and adhered with the help of the oral system and proteolytic enzymes. The thicker part of the parasite protrudes into the lumen of the intestine. Females produce a lot of eggs, which leave with the stool. Eggs must ripen in the outdoor environment for 3-4 weeks to be infectious.
Clinical picture
If there are a small number of adults in the gut, then the infection is usually asymptomatic. On the contrary, massive infection is manifested by pain in the upper abdominal cavity and noticeable blood loss. Infections are often associated with other parasitosis, malnutrition , and chronic gastrointestinal disorders. In children, this infection is especially dangerous because it can cause growth disorders and even mental retardation.
Massive infections (especially in the tropics) manifest themselves as:
- indigestion;
- pain in the right upper abdomen;
- blood loss;
- tenesmy ;
- bloody and slimy diarrhea ;
- anemia ;
- growth disorders in children ;
- rectal prolapse
Diagnosis and therapy
We use stool eggs for diagnosis. The shape of the eggs is characteristic, it has the shape of a lemon.
It is a relatively resistant worm and the antiparasitic drugs mebendazole and albendazole are most often used for treatment.
