Opis:
During long-term (1998-2000) studies on rodent parasite populations in Mazury lake district there were collected and analyzed data on co-occurrence of intestinal protozoa (Cryptosporidium parvum, Giardia spp.) and helminths. There were performed 178 autopsies of common vole Microtus arvalis, 85 autopsies of yellow-necked mouse Apodemus flavicollis and 386 autopsies of bank vole Clethrionomys glareolus. Positive effect of helminth infections was found in C. glareolus. Voles infected with nematode Heligmosomum mixtum showed higher prevalence of C. parvum and Giardia spp. than voles infected with Heligmosomoides glareoli. The host age took part in these interactions and positive effect of co-occurrence was mainly observed in voles older than 3 months. The other intrinsic (host sex) or extrinsic (season and year of study) factors influenced interactions between parasites. Presented results revealed that helminth infections may facilitate chronic infections of intestinal protozoa in rodent populations.

Cryptosporidium
Opis:
Cryptosporidium spp. and Giardia spp. are intestinal protozoan parasites of humans and many other species of mammals. The aim of this article was to summarize the last twenty years of research on the environmental distribution of these parasites, with a particular emphasis on the natural reservoir of invasion and human infections in Poland. The prevalence of Cryptosporidium and Giardia has been studied in different groups of humans, in wildlife, pets and farm animals and in environmental samples. Current knowledge on the distribution of zoonotic and non-zoonotic species/genotypes in reservoir hosts and environmental samples has been summarized. The usefulness of different methods for the detection and identification of the parasites in different types of samples has been presented. Due to the wide distribution and high prevalence of both species in a range of hosts and possible vectors involved in mechanical transmission, the overall risk of outbreaks of cryptosporidiosis and giardiosis in Poland has been assessed as relatively high.

Opis:
Cryptosporidium and Giardia spp. are parasitic protozoa localized in the alimentary tract of many animal species and humans. Each of these parasite species produces very resistant invasive forms (cysts and oocysts) excreted to the environment with feces of infected hosts. Water contaminated with cysts/oocysts constitutes one of the main transmission routes and is responsible for the majority of infections in humans. Cryptosporidium and Giardia spp. were found in many different species of animals, including livestock, pets and free living animals. The aim of our study was to determine the prevalence of these protozoa in selected species of semi−aquatic mammals and to estimate their role in water contamination. In years 1996–98 the prevalence of Cryptosporidium and Giardia infections was high in muskrats (Ondatra zibethicus) (58 and 87%, respectively). The origin of animals (farmed or free living) affected the prevalence of both parasites in European beavers (Castor fiber). The prevalence of infection increased in second period of study and was 4 and 19% for Cryptosporidium and 0 and 8% for Giardia spp. in the two studied periods, respectively. Both parasite species were also identified in water vole (Arvicola terrestris) and rat (Rattus norvegicus).

Opis:
Cryptosporidium spp. and Giardia spp. are wide-spread pathogens of humans and many species of mammals. The ways of transmission are very complex and diffi cult to defi ne. Both parasites occur in similar environments and share a broad host range. However, in Poland there is still little known about the epidemiology of these parasites due to the paucity of data on human cases and only few studies in wildlife. The aim of our study was to determine the distribution of two intestinal protozoa in a few species of protected and game mammals in North-Eastern Poland. Additionally, we wanted to compare prevalence and abundance of these parasites between wild and farm animals, and to determine the species/genotypes of Cryptosporidium. Fecal samples collected from protected species (European beaver – 22, grey wolf – 14, European bison – 55, Polish Konik (horse) – 5) and game mammals (red deer – 52, roe deer – 22, boar – 5) were examined by IFA. We also studied a group of samples collected from farm animals: beaver – 30, red deer – 66, Polish konik – 5. Cryptosporidium oocysts were identifi ed in 5 of 7 studied animal species (prevalence from 9% in roe deer to 36% in wolves), Giardia cysts in 4 of 6 studied species (prevalence from 1.7% in red deer to 7.7% in European beaver). Sequencing analysis of COWP gene fragment revealed that 5 Cryptosporidium isolates from wolves were C. parvum genotype 2 (zoonotic). The results show the important role of examined species in maintaining the natural sources of Cryptosporidium spp. and Giardia spp. infections in the environment.

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.
