Generalized parvovirus infection with inclusion-body myocarditis in two kittens.

Two 13-day-old kittens showed a disease characterized by degeneration, inflammatory response and inclusion bodies in intestine, liver and in one case the myocardium. Inclusions contained typical parvovirus particles. Either a generalized parvovirus infection by the causal agent of feline panleukopenia or an infection due to an unknown parvovirus is considered a possible cause of the disease. A possible relationship of the agent to canine parvovirus is also considered.
