Abstract
A number of cat colonies in The Netherlands, in which upper respiratory tract disease (U.R.D.) was endemic, were examined for the presence of feline herpes virus (H) and feline calici virus (C) infections. In total 108 cats were examined. In 59% of the cases feline calici virus was isolated and feline herpes virus in 39% of the cases. Mixed infections were found in 26% of the cats. The virus isolates were all neutralised by anti-sera against attenuated strains of feline herpes virus and feline calici virus which are incorporated in a newly developed combined C-H vaccine against U.R.D. in cats. Intranasal application of this vaccine induced a distinct increase in resistance against experimental challenge with virulent C and H, as soon as 24 hours after vaccination.
