INFESTATION WITH GONGYLONEMA (gongylonematosis) — helminthosis from group of nematodoses, the activator to-rogo is Gongylonema pulchrum Molin, 1857.
It is for the first time described at the person J. Leidy in 1850. Till 1972 34 cases are registered: in the USA — 10, in the USSR — 8, in Bulgaria — 4, in Italy — 3, in the People's Republic of China — 3, in Morocco — 2, in Austria — 1, in Hungary — 1, in Yugoslavia — 1, in Sri Lanka — 1.
Gongilonema — the thin nematode, on the head end a cut is available 8 longitudinal rows of roundish or oval plaques. A male of 30 in size — 62 X 0,2 — 0,36 mm; female 74 — 145 X 0,275 mm. Eggs with a thick transparent cover, contain the created larva; the size of eggs is 0,05 — 0,067 X 0,023 — 0,037 mm. Adult gongilonema parasitize at large and small cattle, domestic and wild pigs, deer, bears, hares, rabbits, horses, monkeys; are registered at the person. Eggs gongilony are allocated together with excrements of animals — final owners — in external environment and zaglotana can be intermediate owners (different types of arthropods, napr, water pennyworts, cockroaches, etc.); in their intestines the larva leaves egg, migrates in a perigastrium where develops, fades twice and then is encapsulated. After death of an insect of a larva can it is long to survive in reservoirs (R. S. Chebotaryov and V. P. Polishchuk, 1961).
At a proglatyvaniye of the infected insect or larvae gongilony the final owner the last are implemented into a wall of a gullet or a small bowel where grow to a puberal stage; the number them at the final owner varies from 1 to 100. People catch G. at an accidental proglatyvaniye of the infested insects — intermediate owners — or drink of the water infected with larvae from open reservoirs.
At the person of a gongilonema are localized on a mucous membrane of an oral cavity (a top and bottom lip, the interior of cheeks, under language, etc.) where small papules are formed; patients complain of an itch, tooth pain, in a throat, difficulty of the movement by language and during the swallowing. On a mucous membrane of an oral cavity the grazes surrounded with a zone of a hyperemia, the zigzag courses are visible. Also strengthened salivation, occasionally with blood, the phenomena of stomatitis and pharyngitis is observed.
Recurrent disease is characteristic, irritability, sleeplessness, headaches is often noted.
The diagnosis is made on the basis of definition of the helminths extracted from a mucous membrane.
Treatment: extraction of parasites after a superficial section of a mucous membrane.
The forecast — is favorable during removal of helminths.
Prevention. Disinfecting (boiling) of drinking water from open reservoirs.
