From 1984 to 1988 one thousand serologic investigations of laboratory animal colonies originating from 10 different European countries were performed. The most prevalent infections in mouse stocks were caused by Mouse hepatitis virus (MHV), Minute virus of mice (MVM), Theiler's encephalomyelitis virus (TEMV), Reovirus type 3 (Reo3), Sendaivirus, and Pneumonia virus of mice (PVM). In mice no infections with Lymphocytic choriomeningitis virus (LCM), Polyomavirus, Mouse adenovirus, and K-virus were recorded. Only two colonies were infected by Ectromelia virus. The first six virus infections of mice were also found in rat colonies as well as the rat-specific Coronaviruses (Sialodacryoadenitisvirus--SDA, Rat corona virus--RCV) and Parvovirus (Kilham rat virus--KRV, Toolan H-1 virus) being endemic. Antibodies to Bacillus piliformis were detectable in about 50% of rat stocks screened. This is in contrast to the mouse, where only about 10% of the colonies were found to be positive. A similar picture was seen for M. pulmonis which is primarily an infection of the rat. In mice no case was detected during the last two years. The number of investigations performed from guineapig, hamster and rabbit colonies was relatively low. Nevertheless, antibodies against the following antigens were detectable: In guineapig stocks: Reo3, PVM, Sendai, Simian virus 5 (SV5) and B. piliformis; in rabbits: Reo3, Sendavirus, SV5, and B. piliformis; in hamsters: PVM, LCM and B. piliformis. The overall contamination rate showed a continuous decrease until 1988. Nevertheless, about 50% of mouse and rat stocks still exhibited antibodies to one or more viral infections.

From 1988 to 1997, a total of 69 mouse colonies and 36 rat colonies were examined for the presence of antibodies to 14 indigenous viruses of mice and rats. Among mouse viruses, high positivity rates were observed with mouse hepatitis virus (MHV), Theiler's encephalomyelitis virus (THEMV), minute virus of mice (MVM), Sendai virus and pneumonia virus of mice (PVM); the prevalence rates were high in rats with Khilam's rat virus (KRV), THEMV, Toolan's H-1 virus, Sendai virus, Parker's rat coronavirus (RCV/SDA) and PVM. During the last decade, the prevalence of some agents such as MHV, Sendai virus, THEMV, PVM and MVM has apparently decreased although they were still present in 1997 (except for PVM). Another point is the constant increase of colonies found free of viruses through this decade, demonstrating the efforts of the French research community to increase the quality of hygiene in laboratory animals.
