EFFECTIVE REMEDY AGAINST COCCIDIA OOCYSTS IN FUR-BEARING ANIMALS

We studied the efficacy of Isodez in different concentrations consisting of two active substances and excipients at a dose of 0.5 L/m2 at a 2-hour exposure against Coccidia oocysts in foxes and Arctic foxes in environmental objects. The experiments were performed in the Institute Laboratory and on one of the Moscow Region fur farms in 2019–2020. Under production conditions, the efficacy of Isodez 6% against Coccidia oocysts in the foxes and Arctic foxes was determined by their artificial laying on experimental sites. When the fur animals were artificially infected with these protozoa, the intense-effectiveness (IE) of Isodez was 92.6 and 96.7% at its 5% concentration, 100% at 6% and 7% concentrations, and 64.7–84.5% of the Phenol solution (basic drug) at 5% concentration, respectively. Under the production conditions, the IE of a 6% Isodez solution reached 94.8% at a dose of 0.5 L/m2 and a 2-hour-exposure against Coccidia oocysts in the foxes and Arctic foxes. The results obtained in the experiment and under production conditions make it possible to recommend Isodez consisting of benzalkonium chloride, formaldehyde and surfactants for disinvasion of environmental objects against Coccidia oocysts of the foxes and Arctic foxes.
