Generic sample from Zalophus californianus
Zalophus californianus
Nasal swabs from two confirmed calicivirus infected California sea lions (Zalophus californianus) (one from 2004 and one from 2006), and a virus isolate from the 2004 swab that was isolated onto BSC40 Vero cells and passaged five times were used for this study. Both animals were from the same managed collection with open water access.  The duration of clinical signs and severity of SMSV infections during 2006 were greater than those during 2004.
