Zoonotic trichuriasis in humans.


Trichuriasis is a chronic geohelminthosis with disorders of gastrointestinal tract, anemic and neuroasthenic syndromes. It is a neglected nematode disease, especially in tropical countries, with approx. 604-795 million people affected and a global spread of 22-44.9%. It is caused by nematode parasites of the genus Trichuris, including over 20 species that infect the colon of the host. Human zoonotic trichuriasis is most often caused by the animal parasites Trichuris vulpis and Trichuris suis. Most often suffer people who do not respect personal hygiene, have contact with soil, sewage and especially animals (dogs, pigs) or use animal manure in plant production. Most cases have been reported in children and in institutionalized patients. In this review the authors summarize the interesting cases of human zoonotic trichuriasis in the world literature, highlight the role of stray or poorly grown dogs for environmental contamination with zooparasitic elements, possible cross-trihcurian invasions between humans and pigs and the necessary prophylaxis. No cases of zoonotic trichuriasis in humans have been reported in Bulgaria yet.
