| Abstract: | Abstract Extract Increasing references have been made in the recent veterinary literature to malacic diseases of the nervous system in sheep and other animals. Plowright (1954 Cordy, D. R. 19S4. J. Neuropath., 13: 330–330. Google Scholar]) and Innes and Plowright (1955 Hartley, W. J. 1956. N.Z.vet.J., 4: 129–129. Taylor &; Francis Online] , Google Scholar]) have described a focal symmetrical spinal poliomalacia of unknown aetiology in sheep in Kenya. In the U.S.A., Cordy (1954 Haymaker, W., Ginzler, A. M. and Ferguson, R. L. 1952. Military Surgeon, 111: 231–231. Google Scholar]) has described a focal symmetrical encephalomalacia of horses following the ingestion of a species of thistle, and Jensen et al. (1956 Hurst, E. W. 1940. Aust. J. exp. Biol. med. Sci., 18: 201–201. Google Scholar]) have described an idiopathic polio-encephalomalacia in cattle and sheep. In New Zealand, Hartley (1956 Innes, J. R. M. and Plowright, W. 1955. J. Neuropath., 14: 185–185. Google Scholar]) has described a focal symmetrical encephalomalacia (F.S.E.) of lambs that may be related to the sublethal effects of the toxin of Clostridium perfringens (welchii) Type D. Smith (1957 Jensen, Rue, Griner, L. A. and Adams, O. R. 1956. J. Amer. vet. med. Ass., 129: 311–311. PubMed] , Google Scholar]) has described widespread lesions of polio-encephalomalacia together with eosinophilic meningoencephalitis in sodium chloride poisoning of swine. |
