Infections with Trichinella spiralis passing from Mother to Filial Mice Pre- and Post-natally

Abstract

It has been shown that mice became infected after suckling from a female which has migrating Trichinella spiralis larvae within her body. The infections are usually of a very low order indicating that adult worms are not being picked up from the mother's faeces but that the infection is probably through the milk. It is also concluded that pre-natal infection of mice with T. spiralis occurs only rarely, if at all.
