title: A serological survey on 15 murine pathogens in mice and rats.
abstract: A serological survey for 15 murine pathogens was performed on 269 mouse sera collected from 21 conventional and 12 barrier colonies, and on 376 rat sera collected from 21 conventional and 23 barrier colonies. Animals having an antibody against at least one of the antigens were contained in 81.0% of conventional and 16.7% of barrier mouse colonies and also in 81.0% of conventional and 43.5% of barrier rat colonies. Main contaminants were mouse hepatitis virus and Sendai virus in mice, and Sendai virus and pneumonia virus of mice in rats. Results also indicated that antibodies to Toolan's H-1, minute virus of mice and PVM were positive in mice from a considerable number of colonies and those to Kilham rat virus, Mycoplasma pulmonis and Toolan's H-1 were sometimes detected in rats, suggesting prevalences of these pathogens in mice and rats in Japan.
