The unicellular parasite Giardia duodenalis has been divided to eight assemblages (A-H) from which A and B have the most important zoonotic potential. All remaining genotypes have a strong commitment to various host animals. We present here the first clinical case of a human infection with the dog-specific genotype C of G. duodenalis in Slovakia. The patient, 44-year-old woman, suffered from long-term diarrhoea, abdominal pain, anorexia, weight loss, severe itching and dermatitis in the perianal area. The initial microscopic diagnosis was completed by a nested polymerase chain reaction (PCR) which revealed the first evidence of human giardiasis caused by the dog-specific genotype of G. duodenalis on a European scale. A possible role of dogs in zoonotic transmission of giardiasis and its epidemiological and public health relevance is accentuated.
