Secondary hydatidosis in Swiss Albino mice following infection with protoscolices of Echinococcus granulosus of buffalo origin

Abstract

Swiss albino mice were experimentally infected with protoscolices of Echinococcus granulosus of buffalo origin through intraperitoneal route. From 3-month post infection (pj), small spots ofechinococcal foci «1 mm) were recorded on the surface of liver, lungs, spleen and kidney. At six-month infection, maximum number of cysts (> 1 mm) were recovered. Cysts or cystic foci were recorded from 66.66% of infected mice. Splenomegaly and hepatomegaly were the predominant gross changes in experimental infection. Histopathological changes in the organs of mice due to secondary hydatidosis have been discussed in the paper.
