The influence of selected viral pathogens on rats that were previously infected with Corynebacterium kutscheri was investigated. A series of three separate experiments were performed to test the effect of sialodacryoadenitis virus, Sendai virus and rat virus. In each experiment, weanling rats were divided into three groups (C. kutscheri-inoculated, virus-inoculated and C. kutscheri plus virus-inoculated). Two groups were inoculated oronasally with C. kutscheri to establish subclinical infections. Two weeks later, two groups were inoculated intranasally with virus. At 5 weeks, the prevalence of C. kutscheri recovery from oral cavity and submaxillary lymph node and the prevalence of overt pseudotuberculosis was compared between treatment groups. Seroconversion of rats to C. kutscheri was measured by microagglutination and viruses by indirect immunofluorescence assays. Infection of rats with sialodacryoadenitis virus, Sendai virus or rat virus had no discernable effect on C. kutscheri-infected rats.
