| Summary: | <i>Cryptosporidium</i> spp. and <i>Giardia duodenalis</i> are zoonotic food- and water-borne protozoa of veterinary importance. They are one of the main causes of diarrhea in domestic dogs (<i>Canis familiaris</i>). Wild canids, such as red foxes (<i>Vulpes vulpes</i>) and raccoon dogs (<i>Nyctereutes procyonoides</i>), can act as natural reservoirs for these parasites. The aim of this study was to estimate the prevalence of these pathogens and analyze possible factors that may affect the infection in wild and domestic canids. A total of 373 domestic dog, 219 red fox, and 78 raccoon dog fecal samples were collected and tested for <i>Cryptosporidium</i> spp. and <i>G. duodenalis</i> presence with direct immunofluorescent staining. The dog owners filled a questionnaire on the dog’s habits and lifestyle to identify and analyze potential factors that may affect the occurrence of these parasites in dogs. <i>Cryptosporidium</i> spp. were found in 16.3%, 28.3%, and 28.2% and <i>G. duodenalis</i> in 0.7%, 27.4%, and 30.8% of the examined dogs, red foxes, and raccoon dogs, respectively. The highest prevalence was observed in puppies—15.4% and 18.5% for <i>Cryptosporidium</i> spp. and <i>G. duodenalis</i>, respectively. In all three canid species, infection with <i>Cryptosporidium</i> increases the risk of co-infection with <i>Giardia</i> and vice versa. |
