Epizootiological monitoring studies on parasitoses of domestic ruminants indicate that one the most common causes nematodes digestive tract in large and small cattle are helminths genus Trichuris. Those develop directly – without intermediate hosts, their embryonic stages became invasive environment under favorable conditions. The eggs those parasites incredibly resistant can be infective for a...

In this paper the differentiation of external morphology and ontogeny of Oribatulidae were investigated, on the basis of Phauloppia lucorum (C. L. Koch, 1841), Lucoppia burrowsi (Michael, 1890), and Oribatula tibialis (Nicolet, 1855), which ontogeny is described and illustrated here for the first time. The juveniles of these species have smooth cuticle, a clavate sensillus with barbed head, and...

Geohelminths parasitizing sheep are widespread throughout the world and have a significant pathogenic effect on animal body. Among them, one of leading places in terms distribution is occupied by helminths genus Trichuris. This due to high resistance trichurises effects chemicals adverse environmental factors. The presence viable eggs trichurosis pathogens surface layer soil sufficiently long p...
