Abstract

A 5-year (1959–1963) virologic and serologic survey in Kern County, California, revealed that wild mammals had been infected with several arboviruses. Seven strains of virus were recovered from 1,889 blood samples: 2 strains of western equine encephalomyelitis (WEE) virus from 1 and 1 , 4 strains of a Simbu group virus from 3 and 1 , and 1 strain of an adenovirus from . No virus was isolated from ticks or fleas. Based on hemagglutination-inhibition tests, antibodies to WEE virus were frequent in but rare in other species. Antibodies to St. Louis encephalitis (SLE), Powassan, and/or Modoc virus, but not Rio Bravo virus, were widespread. The yearly prevalence of antibodies to any one group B arbovirus varied. Antibody to SLE virus decreased and antibody to Powassan virus increased over the 5-year period. WEE viral antibody rates in paralleled viral infection rates in and immunity conversion rates in sentinel chickens. No such relationship was found for WEE and SLE viral antibodies in rodents.
