Histopathological changes in the brain of mice given Clostridium perfringens type D epsilon toxin

J Comp Pathol. 1984 Jul;94(3):363-70. doi: 10.1016/0021-9975(84)90024-0.


The distribution, severity and frequency of brain lesions produced in mice by the administration of Clostridium perfringens Type D epsilon toxin were examined by light microscopy. The granular layer of the cerebellum was the area most frequently affected in mice given single doses of toxin. Sequential changes in brain morphology were examined from 1 h to 7 days after injection of toxin. Lesions progressed from an initial vasogenic oedema to malacic foci which commonly were focal and bilaterally symmetrical, with a predilection for white matter. The topographical distribution of these malacic areas is discussed.
