ABSTRACT:
[i]Cryptosporidium[/i] spp. and [i]Giardia[/i] spp. have been detected in a range of host species, including rodents. The aim of this study was to determine the distribution of these pathogens and recognition of the reservoir role of rodents in the maintenance of these pathogens in south-western Poland. Additionally, preliminary molecular studies were conducted to elucidate the species and genotypes of [i]Cryptosporidium[/i] and [i]Giardia[/i] identified in this study. Stool samples (n=266) from [i]A. agrarius[/i],[i] A. flavicollis[/i] and [i]M. glareolus[/i], were subjected for analyses. Values of prevalence were 61.7, 68.3 and 68.1%, respectively, for [i]Cryptosporidium[/i] spp. and 41.7, 24.4 and 38.4%, respectively, for [i]Giardia[/i] spp. There was a statistically significant correlation between host species and [i]Giardia[/i] infection where[i] A. agrarius[/i] was the species of the highest prevalence. Statistically significant differences were not found for comparisons made for study sites and occurrence of [i]Giardia[/i] spp. and [i]Cryptosporidium[/i] spp. Due to preliminary nested PCR results, specific amplifications of [i]Cryptosporidium[/i] COWP and SSU rRNA genes were obtained for several isolates taken from rodent host species. One isolate recovered from [i]A. agrarius[/i] (from a semi-aquatic, urban area) was identified as [i]C. parvum[/i] and revealed 100% similarity with sequences obtained from humans. To the best of the knowledge of the authors, this is the first record of the [i]C. parvum[/i] zoonotic species from the striped field mouse. Also recorded were the first findings of [i]C. ubiquitum[/i] from three small rodent species.
