The distribution of Ancylostoma caninum larvae in the central nervous system of the mouse infected with single or repeated doses

Abstract

ABSTRACTThe distribution of Ancylostoma caninum larvae in the various regions of the central nervous system of mice of previously uninfected or reinfected groups was studied. Although a dose of 4000 larvae was lethal, the distribution of larvae was not appreciable in the CNS. Many larvae were recovered from the cerebral hemispheres and cerebellum of infected mice whereas no incidence of eye involvement was observed in any mouse. In the reinfected mice groups there was a much lower recovery than in the previously uninfected groups in the latent period of study.
