Experimental visceral larva migrans in chicken with Toxocara canis

Abstract

The aim of this study was to determine the distribution of Toxocara canis larvae in some organs of chicks and to clarify if the larvae found in brain will be able to lead to the behavioral disorder or not. For this purpose, 42 15-day-old broiler chicks were allocated to 6 groups, each consisted of 5 trial and 2 control animals (Totally 30 exp. and 12 contr. anim.). Each experimental chick recevied 5000 embriyonated T. canis eggs orally. All animals were necropsied between 2(nd) and 12(th) days after inoculation with two day intervals. Brain, lung, liver and a half carcass of animals were digested in the pepsin-HCL solution and the digested organs were examined for the presence of larvae.
