Snowshoe hare virus (SSHV) or JCV and various dilutions of deer serum samples were incubated at 37[degrees]C for 1 h in tissue culture media, then added to Vero cell monolayers.
California serogroup (CSG) viruses (family Bunyaviridae, genus OrthobunyaviruS) (1) include the mosquitoborne pathogens Jamestown Canyon virus (JCV),
snowshoe hare virus (SSHV), and La Crosse virus.
CHATV strains have [approximately equal to] 84% aa identity with INKV within the nucleocapsid protein but are more similar to the
Snowshoe hare virus (93% nucleocapsid protein identity) that occurs in the United States.
The titers for the convalescent-phase serum were 1:320 for California encephalitis and 1:180 for the closely related
snowshoe hare virus (Table), which has never been reported in California.
