Besides group A rotaviruses, group B and C rotaviruses have been detected as the cause of diarrheal diseases in pigs. Of a set of 329 faecal samples from pigs, 16 samples were selected in which rotavirus was detected by electron microscopy and at the same time group A rotavirus was excluded by ELISA method. Rotaviruses were assayed using specific primers for detection of group B and C rotaviruses, and RT-PCR and semi-nested PCR methods. In one sample, no rotavirus of group B or C was detected; in the remaining 15 samples rotavirus group C was detected, in two samples together with group B rotavirus. Sequencing of the obtained PCR products and comparison with corresponding gene sequences revealed 80% nucleotide sequence identity between group B rotaviruses and available sequences of porcine isolates. A nucleotide sequence identity of 92% was obtained in group C rotaviruses as compared with the Cowden strain.

Keywords: group B rotavirus; group C rotavirus; nongroup A rotavirus; enteritis; RT-PCR, semi-nested PCR
