IN-VIVO OVICIDAL EFFECT OF MEBENDAZOLE ON BAYLISASCARIS TRANSFUGA EGGS

Abstract

Mebenzadole was tested for in vivo effect on the eggs of B. transfuga recovered from polar bears treated with the drug. A marked reduction of the number of eggs that developed to the larval stage was observed. The pre-treatment percentage of incubated eggs that developed to the larval stage was 80 %-92 %. On day 1, after treatment was starting, the percentage was 26 %-70 %, on day 2 the number was 0 %-9 % and on day 3 it was 0 %-1 %. No eggs developed on day 4 and thereafter. Coprological examinations were negative after 4-7 days the treatment was starting
