[The helminth fauna structure of wild rodents from differential sites of Wrocław area].


The parasite fauna of rodents was studied in the Wrocław area from 2001 to 2005. The first location was irrigation fields (Wrocław Osobowice), the second--a water distribution area (Wrocław Mokry Dwór). Helminthological material was collected during parasitological examination of 447 specimens of wildlife rodents (belonging to 7 species of Muridae). The helminth population and the helminth communities' structure were analyzed, their qualitative and quantitative characteristics were described by parasitological and ecological parameters. Significance of differences was tested by the chi-square test. Prevalence data was analysed by maximum likelihood techniques based on log-linear analysis of contingency tables using Statistica v.7.1. for ecological analysis Estimates was used. A total of 7787 helminth specimens belonging to 32 taxa were found: 16 nematodes, 12 cestodes and 4 digeneans. Any species of Acanthocephala was reported. The prevalence of helminths was 73.8%, mean intensity of infection--23.6 and mean abundance--17.4. In results of this research the new species of fluke Brachylecithum galreoli was described. Four species of nematodes were reported as new for Polish helminth fauna. Seventeen helminth species were found for the first time in Lower Silesia. The study showed qualitative and quantitative differences in the compound community and component community structure of helminths depending on site-specific conditions. A comparison of the helminth communities of Apodemus flavicollis revealed the biggest differences. This research did not reveal a statistically significant influence of host sex on total prevalence of infection. The differences in seasonal activity of small rodents had influence on prevalence of helminths. The parasites occurred proportional more frequently in summer and autumn in rodent populations. Co-occurrence of helminth species in individual host was observed (56.1% of rodents infected). The most frequent co-occurrence was of two species Heligmosomoides polygyrus and Trichuris muris parasitizing the yellow-necked mouse. These relationships were positive and statistic significant.
