Host range comparisons of five serotypes of caliciviruses

Two new serotypes of San Miguel sea lion virus (SMSV), designated SMSV-4 and SMSV-5, were studied in vivo and in vitro. The host cell spectrums were compared with SMSV-1, SMSV-2, and vesicular exanthema of swine virus type A-48. Based on the result of these broad host spectrums, a numerical scoring system was devised for ranking each virus on the basis of its potential for infecting terrestrial mammals, including the important domestic species.
