Many species of tapeworms of the family Taeniidae are of great importance for human and veterinary medicine, while rodents are important intermediate hosts for some of the species. The role of rodents in the tapeworm’s transmission dynamics depends on various external and internal factors. This study aimed to determine the presence of larval forms of tapeworms in rodents and molecular detection of the species, as well as to examine the relationship between different morphological, parasitological, and physiological characteristics of the host. In the period from 2013 to 2021, a total of 770 individuals belonging to the species: Apodemus flavicollis, Apodemus agrarius, Apodemus sylvaticus, Myodes glareolus, Microtus arvalis, and Microtus subterraneus, collected from 42 different localities in Serbia, were examined. Cysts and visible lesions in the body cavity and various organs were detected in a total of 47 individuals. Using the mitochondrial marker 12S rDNA, three species were identified: Taenia taeniaeformis, Taenia martis and Taenia crassiceps. In the entire sample, of all host species, the difference in the percentage of infected individuals depending on the sampling site was proven (χ2=66.7, p=0.007). In addition, diference between rodent species in spleen size, body length and weight, and body condition (BCI) were also significant (Kruskal-Walis test, all p <0.001). In A. flavicollis, males showed higher body length (p=0.024), body mass (p=0.003) and BCI (p=0.003), while in other host species sex did not differ in mentioned parameters (Mann-Whitney test, all p>0.05). In A. flavicollis, spleen and BCI were statistically significantly higher in individuals with tapeworm larvae (p<0.005). Regression analysis in this host showed a positive correlation between spleen size and leukocyte count (WBC) (r=0.221; p=0.014). No difference was found between infected and uninfected individuals for WBC. In M. arvalis, females being more infected than males (χ2=3.884, p=0.049). Regression analysis showed a significant positive correlation of spleen size with body mass (A. agrarius: r=0.669; p<0.001, A. flavicollis: r = 0.668; p<0.001, A. sylvaticus: r = 0.753; p<0.001, M. arvalis: r=0.562; p = 0.005, M. glareolus: r = 0.546; p = 0.004) and BCI (A. agrarius: r=0.608; p <0.001, A. flavicollis: r=0.663; p<0.001, A.sylvaticus: r=0.652; p=0.001, M. arvalis: r=0.481; p=0.020, M. glareolus: r=0.550; p=0.004), except in M. subteraneus. This research represent the preliminary results of molecular analysis of taeniid species in rodents in our country and their relationship with morpho-physiological characteristics of host.
