EXPERIMENTAL CEREBROSPINAL NEMATODIASIS (PNEUMOSTRONGYLUS TENUIS) IN SHEEP

Abstract

Six lambs were each infected experimentally with 50–1000 infective larvae of Pneumostrongylus tenuis. Three animals displayed neurologic signs. Lesions and dead or living worms were found in the central nervous system of all infected lambs. It is concluded, however, that sheep have a good natural resistance to infection and that P. tenuis will not mature in them. Before P. tenuis is diagnosed in naturally infected sheep it would be advisable to establish whether the sheep have been in contact with white-tailed deer, the normal host.
