Opis:
The studies were carried out in Kosewo Górne in the Mazurian District (North-East region of Poland), in September 1995, September 1996 and between May 1997 and June 1998 each month. The animals were trapped in live traps, and after study they were marked and released. The infection of trypanosomes was detected using microhaematocrit centrifugation technique and in blood smears. The intensity of infection had the range from 50 to 150000 individuals in 1ml of blood. The maximal prevalence of infection was in August and September and there were 45% and 38% of infected voles respectively. The infection was detected also in May 1998, in other months the prevalence had low level. There were no individuals of bank vole infected in succecding months. The females of bank vole are more often infected with trypanosomes than males.

Opis:
Fragmentation of the environment by natural barriers (lakes, mountain ranges) and human activities (towns, major roads, agriculture) can lead to isolated subpopulations of hosts. The study was carried out in Mazury Lake District in North−East of Poland, the region rich in forests, lakes, rivers and canals, which are able to create passable such barriers. Population of bank voles (Myodes glareolus) and yellow−necked mice (Apodemus flavicollis) — dominant woodland rodents — showed local differences in helminth communities in fragmented forest habitat. The sites were chosen on the basis of the similarity of their habitat structure and type, and isolation from one another. The impact of nematode (Heligmosomoididae) infections on co−occurrence and dynamic of Cryptosporidium parvum infection was studied in both rodent species Myodes glareolus (n=781) and Apodemus flavicollis (n=302) from three different habitats. Presented results clearly revealed that natural nematode invasion could facilitate the presence of chronic infections of Cryptosporidium parvum in wild rodent populations. Also, the intrinsic (host sex and year) as well as extrinsic (season and year of study) factors have obvious effect on dynamics of infections with both groups of parasites. However, there are also some evidences that steroids hormones associated with stress and reproduction may mediate trade−offs between physiology and immune function and can affect co−occurrence of both groups of parasites.

Opis:
The prevalence and abundance of Cryptosporidium parvum were studied over a three year period (1997-1999) in three species of rodents sampled from forest and abandoned fields in the Mazury Lake District, Poland. The overall prevalence was consistently higher in voles compared with Apodemus flavicollis (70.6% in Clethrionomys glareolus, 73.0% in Microtus arvalis and 27.8% in A. flavicollis). The prevalence and abundance of infection also varied across the 3 years of the study with 1998 being the year of higher prevalence and abundance of the parasite. Fewer older animals carried the infection, and their infections were relatively mild. We found no consistent pattern of seasonal changes despite the significance of seasonal differenccs. Host sex did not influence either the prevalence or abundance of infection with C. parvum. A great proportion of recaptured voles developed chronic infections between consecutive trapping sessions and only a small number of animals recovered. However, yellow-necked mice seem to be much more resistant to infection that became self-limiting. Our results firmly establish that the common woodland and grassland wild rodents in the Mazury Lake District constitute a significant and hazardous reservoir of C. parvum for animals and humans.

Opis:
The maintenance of Borrelia burgdorferi s.1. in the environment is dependent on the zoonotic cycle involving tick vectors and certain reservoir hosts. It is well known, that the same species of wild rodents, as well as the vector Ixodes ricinus, are often co-infected with at least two genomospecies of B. burgdorferi s.1.: B. afzelii and B. garinii. The ticks collected from two rodent species: Clethrionomys glareolus and Apodemus flavicollis were examined for the presence of B. burgdorferi s.1., as well as for B. garinii and B. afzelii. In this study, an immunofluorescent antibody assay (lFA) and polymerase chain reaction (PCR) protocols were used. The high level of infestation in rodents (90% for C. glareolus and nearly 100% for A. flavicollis) shows that wild rodents are important hosts of the immature stages of I. ricinus. A high percent of Borrelia positive ticks collected from bank voles and yellow necked mice; above 7% determined by 1FA and 2% determined by PCR, elearly revealed that these species of animals are competent zoonotic reservoirs of B. burgdorferi s.l.
