| Popis: | The purpose of the research is to study the parasite fauna in laboratory rats and mice in SPF-status and open-type vivariums and to compare the infection rate depending on the maintenance type within each type of samples.Materials and methods. The studies were conducted using life-time diagnosis (flotation method and Scotch-tape test), and the material were fecal samples from laboratory rodents and litter samples. Ten percent of the vivarium population and all newly arrived mice and rats in quarantine were examined. Fifty-four individual samples from pure line mice, and 24 litter samples were examined. A total of 234 samples were collected from the laboratory rats: 93 individual samples, 55 combined samples, and 17 sawdust samples; 69 samples were examined by Scotch-tape test.Results and discussion. Twenty six percent of the laboratory SPF vivarium mice were found to have protozoa: Giardia muris (11.1%) and Trichomonas sp. (20.4%). Nematodes Aspiculuris tetraptera (51.0%) and Syphacia obvelata (20.6%), and cestode Rodentolepis nana (12.0%) were recorded in the open-type vivarium mice. The laboratory open-type vivarium rats were found to have nematodes S. muris (up to 60.9%), A. tetraptera (5.4%), Trichosomoides crassicauda (1.8%), cestode R. nana (27.3%), protozoa Eimeria sp. (7.2%) and Giardia sp. (9.0%). The compared infection of individual with combined mouse fecal samples showed statistically significant differences for all parasites in general and for individual species. Pairwise comparisons of the infection showed that the combined sample detected R. nana statistically significantly more often versus the individual sample (27.3 vs. 5.4%, P < 0.001). The comparison of the infection depending on the type of rat maintenance within each sample type did not show statistically significant differences. |
