Disinvasive activity of “Hemastal BIO” and “Staldren” against non-invasive eggs of Trichuris skrjabini nematodes parasitizing sheep

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 period their storage environment represents potential threat parasitic invasion territory farms. aim research was determine disinfestation activity modern ecologically safe means for dry disinfection against non-invasive nematode Trichuris skrjabini sheep. An experimental test preparations “Hemastal BIO” (AS – calcium hydroxide, sulfate, sulfite-semihydrate, chloride) “Staldren” carbonate, pine oil, magnesium silicate, iron oxide) carried out laboratory conditions. In experiment, cultures isolated from gonads T. females were used. results conducted established level efficiency (DE 100 %) relative 54th day cultivation formation invasive control culture. During embryogenesis trichurises, effectiveness disinfectants gradually increased with up 88.84 % 18th 98.36 36th day, 82.79 95.90 days. Their harmful characterized specific changes nematodes form sticking crystals agents around causative agents, as result which there stop growth development gradual decay resorption embryos. Such also confirmed metric parameters width length eggs. obtained data allow recommend purpose effective maintenance sanitary epidemiological well-being relation
