Clinical Signs of San Miguel Sea Lion Virus in Debilitated California Sea Lions

Between late May and mid-December 1984, 32 California sea lions (Zalophus californianus) were brought to the California Marine Mammal Center with vesicular lesions of varying severity on the nonhaired regions of the flippers. Later, large, firm raised areas erupted around the mouth and on the chin o...

Description
Summary:Between late May and mid-December 1984, 32 California sea lions (Zalophus californianus) were brought to the California Marine Mammal Center with vesicular lesions of varying severity on the nonhaired regions of the flippers. Later, large, firm raised areas erupted around the mouth and on the chin of five of these animals. San Miguel sea lion virus (SMSV) serotype 13 was isolated from a vesicle on the flipper of one of the sea lions. Lesions on the flippers and lip margins ulcerated and, depending on their initial severity, took up to 9 wk to heal completely. In addition to the skin lesions, all of the sea lions had concomitant severe medical problems, usually leptospirosis. There was no correlation between the severity of vesicular lesions and the severity of other clinical problems.
