The pinworm (genus Enterobius) is a type of roundworm (nematode), and three species of pinworm have been identified with certainty. [15] Humans are hosts only to Enterobius vermicularis (formerly Oxyurias vermicularis). [16] Chimpanzees are host to Enterobius anthropopitheci, which is morphologically distinguishable from the human pinworm. [5]
Pinworm infection (threadworm infection in the UK), also known as enterobiasis, is a human parasitic disease caused by the pinworm, Enterobius vermicularis. [3] The most common symptom is pruritus ani , or itching in the anal area. [ 1 ]
Soil steaming is an efficient method to kill nematodes before planting a crop, but indiscriminately eliminates both harmful and beneficial soil fauna. The golden nematode Globodera rostochiensis is a particularly harmful pest that has resulted in quarantines and crop failures worldwide.
worldwide: one of the most common human parasites; estimated to infect between 30–50% of the global population. [6] [7] ingestion of uncooked/undercooked pork/lamb/goat with Toxoplasma bradyzoites, ingestion of raw milk with Toxoplasma tachyzoites, ingestion of contaminated water food or soil with oocysts in cat feces that is more than one ...
The most common causes of intestinal parasites are through consumption of contaminated water, infected soil, inadequate sanitation and hygiene, and improper hygiene. [3] Specifically, lack of access to facilities for safe disposal of human waste can result in intestinal parasites and disease.
Due to this strong shell, helminth eggs or ova remain viable in soil, fresh water and sewage for many months. In feces, fecal sludge and sewage sludge they can even remain viable for several years. [ 16 ] [ 17 ] Helminth eggs of concern in wastewater used for irrigation have a size between 20 and 90 μm and a relative density of 1.06–1.23. [ 18 ]
The soil-transmitted helminths (A. lumbricoides, T. trichiura, N. americanus, A. duodenale), schistosomes, and filarial worms collectively infect more than a quarter of the human population worldwide at any one time, far surpassing HIV and malaria together. [35] [37] Schistosomiasis is the second most prevalent parasitic disease of humans after ...
Strongyloides stercoralis is a human pathogenic parasitic roundworm causing the disease strongyloidiasis. Its common name in the US is threadworm. In the UK and Australia, however, the term threadworm can also refer to nematodes of the genus Enterobius, otherwise known as pinworms. [2] The Strongyloides stercoralis nematode can
