Clinical and histopathological studies on visceral larva migrans of toxocara vitulorum in chickens

Two hundred chickens was used in the presen~ experi- ments. They were subdivided to five groups, four ofthem were primary iniected with T.vitulorum in a small (5,000 eggs) and large (20,000 eggs) aoses • In two groups, the chickens were superinfected with interval 28 days from the first one, with the dWlle doses given previously. Blood for hdematologicRl stanalysis and proper tissue samples for histopathologi~al examination were periodically taken each four days for 52nd day the period of experimento Parallel to this sera was obtained for the indirect fluorescence technisue as a diagnostic mean for visceralThe present stuc.l.es revealeci that the inten.sity of fluorescent reaction e·f the infected chickens sera was greatly related to the titre of specific antibodies developed against the invaded parasite. The de~eloped antibody titre due to ti..l.e exposure
