Efficiency of different test cultures of helminth’s eggs for establishing of desinvasive properties of chemicals

Abstract

The comparative efficiency of the usage of test cultures eggs of Ascaris suum and Trichuris suis, isolated from different substrates (gonads of female worms and faeces of sick pigs) in the process of identifying of desinvasive properties of chemicals «Bi-des» and «Brovades-plus». We found that the most resistant to the studied chemicals were T. suis eggs test cultures obtained from faeces of sick pigs. In particular, desinvasive chemicals in 2 % concentration and 60 min exposure led to the death of 68,75–71,85 % of Trichuris suis eggs, isolated from the faeces of sick pigs and 82,60–89,13 % – isolated from the gonads of female worms. However, desinvasive chemicals 100 % were detrimental to the successive stages of Ascaris suum eggs.
