Prevalence and distribution of four serotypes of SMSV serum neutralizing antibodies in wild animal populations

Abstract

Serum neutralizing antibodies to four serotypes of San Miguel Sea Lion Virus (SMSV) were demonstrated in a variety of marine and terrestrial species. These results show a wide geographic distribution of SMS viruses in the marine environment and indicate that certain terrestrial mammals have been infected with these so-called marine viruses. Evidence is presented supporting the theory that unidentified submammalian marine species are a reservoir for SMSV.
