    Group A rotaviruses (RVAs) are widespread in humans and many animal species and represent the most epidemiologically important rotavirus group. The aim of the study was the identification of the genotype pattern of human RVA strains circulating in Poland, assessment of their phylogenetic relationships to pig RVAs and identification of reassortant and zoonotic virus strains. Human stool samples which were RVA positive (n = 166) were collected from children and adults at the age of 1 month to 74 years with symptoms of diarrhoea. Identification of the G and P genotypes of human RVAs as well as the complete genotype of reassortant and zoonotic virus strains was performed by the use of an RT-PCR method. The G (G1–G4, G8 or G9) and/or P (P[4], P[6], P[8] or P[9]) genotypes were determined for 148 (89.2%) out of 166 RVA strains present in human stool. G1P[8] RVA strains prevailed, and G4P[8] (20.5%), G9P[8] (15.7%) and G2P[4] (13.3%) human RVA strains were also frequently identified. The full genome analysis of human G4P[6] as well as pig G1P[8] and G5P[6] RVAs revealed the occurrence of porcine–human reassortants and zoonotic RVAs. Detection of G4P[6] in pigs confirms their role as a reservoir of zoonotic RVAs.
