Isolation of a Feline Virus Associated with Intranuclear Inclusion Bodies

Abstract
A viral agent cytopathogenic for feline kidney tissue culture was isolated from a cat with a respiratory infec tion. It was shown to be capable of producing the illness in susceptible kittens with the development of specific neutralizing antibodies. Intra nuclear inclusions were demonstrated in both tissue culture preparations and kittens in which the disease was reproduced. The agent survived lyophilization and storage in tissue culture fluid for at least 3 months at -60[degree]C.
