Cryptosporidium is an intestinal protozoan parasite prevalent in a wide range of mammals. Although it has been recorded in many hosts, its impact on endangered species is poorly understood. Here we present a preliminary study of four populations of the highly threatened spotted souslik (Spermophilus suslicus), living in the westernmost part of the species range. The populations inhabit fragmented habitats and suffer from loss of genetic variation. An IFA test revealed that 35.9% of sampled animals (41/114) was infected with Cryptosporidium and none with Giardia. The prevalence and infection intensity differed among the populations. In areas grazed by cattle it was about 3 folds higher, which suggests a possible transmission route. To the authors best knowledge the present study is the first report of Cryptosporidium infections in S. suslicus.

The aim of this study was to evaluate the distribution of intestinal protozoa Cryptosporidium spp. and Giardia spp. among the sled dogs taking part in an international competition during the Dryland World Championship IFSS, in Lubliniec, Poland, April 2005. Fecal samples (n = 80) were collected during the race and during two time periods: 2-4 weeks and 6-8 weeks after the race. The immunofluorescent assay (IFA) MerIFluor Cryptosporidium/Giardia was used for the detection of parasite dispersal stages in condensed samples. The influence of a range of factors on the prevalence and the intensity of cyst/oocyst production was estimated. Giardia spp. infections were identified in four studied countries with overall prevalence of 36%. Cryptosporidium oocysts were detected in samples from 2 of 4 countries with an overall prevalence of 12.5%. For both intestinal protozoa an identical dynamics of infection was noted, with the peak in prevalence and cyst/ oocyst production 2-4 weeks after WC, which supports the hypothesis of the enhanced risk of parasite transmission during the race. The number of dogs in kennels, dog sex, and age affected the Giardia infections in sled dogs. The prevalence or intensity of cyst production were higher in kennels with more than 10 dogs, in males compared to females, and in young (<2 years old) dogs. Cryptosporidium infections were more common among males and young dogs, and the prevalence was low among Husky breeds. The co-infections with both parasites were common and the presence of Giardia or Cryptosporidium infection was significantly connected with the presence of diarrhea in dogs. Consequently, it seems that protozoan infections may affect the physical condition and performance of sled dogs and contribute to zoonotic diseases in dog owners.

Wolf scats collected during ecological studies in Mazury lake district in NE Poland were analysed for intestinal micro- and macroparasites. Five nematode species were identified: Ancylostoma caninum (Ercolani, 1859), Uncinaria stenocephala (Railliet, 1884), Trichuris vulpis (Froelich, 1789), Toxocara canis (Werner, 1782) and Toxascaris leonina (von Linstow, 1902). Among cestode species there were identified infections with Dipylidium caninum (Linnaeus, 1785). The overall helminth prevalence was 63.5% and average intensity was 15.4 ± 8.0 eggs /1g of sample. The most prevalent parasite was T. vulpis (38.5%) and the most abundant infections were by T. canis. Almost 55% of samples (28/51) were positive for C. parvum oocysts and 46.7% (14/30) for Giardia spp. cysts. The pack factor affected the distribution of some of macro- and microparasites. The identified parasite fauna of wolves in Mazury lake district consists of several micro- and macroparasites of interest for public health.

Secondary geodiversity (represented by anthropogenic landforms, which can be considered a significant part of geoheritage of certain area) can be seen as an important resource for geotourism and geoeducational activities within urban areas. Brno city (Czech Republic) is rich in these landforms as well as numerous urban areas. Some of them (especially old quarries and underground spaces) are already used for recreation, tourism and leisure or they serve as excursion localities for the university students, some of them are unique from the geoscience point of view and they have also certain added values (historical, archaeological or ecological). However, in some cases, their potential is not fully recognised. The article describes the main anthropogenic landforms within Brno city and analyses their suitability for geotourism and geoeducational activities.

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.
