Abstract

Innovative methods in the diagnostic of parasitic invasions in domestic animals.

Abstract

The authors describe the results of a comparison of traditional and newly proposed methods for diagnosing parasitic diseases of cattle, sheep and horses in Pavlodar region. Along with traditional methods, the authors present the results of their research, obtained using innovative methods of applying antifreeze with the addition of substances that increase the density of the solution. Researchers received the best result in the diagnosis of parasitosis using antifreeze with flotation additives. The diagnostic result of parasitosis, in comparison with traditional methods, exceeded 1.5-2 times when using innovative methods. Fluids containing ethylene-glycol contribute to hustling of helminthes' eggs and coccidian oocysts to the solution surface at the expense of bad adhesion of two-atonic alcohols with the eggs' capsules. In Pavlodar region in the horses we registered nematodes from suborder Strongylata, among which Delafondia sp. was prevalence, Strongylus sp. and Alfortia were recorded more rarely. In goats and sheep among Strongylata suborder the nematodes from genera Chabertia and Heamonchus mainly revealed, helminthes from genus Nematodirus were registered rarely. In young animals nematodes from suborder Ascaridata were met often (Parascaris equorum in foals and Neoascaris vitullorum in calves). In young cattle the single eggs of Trichocephalus sp. and Nematodirus sp. were revealed. In all ruminant species single eggs of Moniezia sp. tapeworms were found. In the excrements of all investigated animals species single Eimeria oocysts were recorded.
