Host-Parasite Relations In Initiation Of Infection: I. Occurrence Of Listeriosis In Arctic Mammals, With A Note On Its Possible Pathogenesis.

A lemming colony maintained at Fort Churchill was examined for the possibility of the presence of L. monocytogenes in latent form, but the organism was not isolated. Following transfer of the lemmings from Churchill to Kingston, L. monocytogens was isolated. In speculation on the pathogenesis of Listerosis, the author suggests that an upset carbohydrate metabolism may be involved in the trigger mechanism. The isolation of L. monocytogenes from a seemingly ill Arctic fox caught at Fort Churchill is reported for the first time.
