Diarrheal feces from three sambar deer and one waterbuck in a wild animal
habitat and one white-tailed deer on a wildlife farm in Ohio contained
coronavirus particles which were agglutinated by antiserum to bovine
coronavirus (BCV) in immune electron microscopy. Three coronavirus strains
were isolated in human rectal tumor cells from the feces of the sambar and
white-tailed deer and the waterbuck, respectively. Hemagglutination,
receptor-destroying enzyme activity, indirect immunofluorescence,
hemagglutination inhibition, virus neutralization, and Western blot
(immunoblot) tests showed close biological and antigenic relationships
among the isolates and with selected BCV strains. Gnotobiotic and
colostrum-deprived calves inoculated with each of these isolates developed
diarrhea and shed coronavirus in their feces and from their nasal passages.
In a serological survey of coronavirus infections among wild deer, 8.7 and
6.6% of sera from mule deer in Wyoming and from white-tailed deer in Ohio,
respectively, were seropositive against both of the isolates and selected
BCV isolates by indirect immunofluorescence tests. These results confirm
the existence of coronaviruses in wild ruminants and suggest that these
species may harbor coronavirus strains transmissible to cattle.
