Identification of bovine and porcine rotavirus G types by PCR.
A new seminested PCR typing assay has been extended to identify the important veterinary rotavirus serotypes G5, G6, G10, and G11, as well as the rare human serotype G8. The specificity of the method was evaluated with 30 standard laboratory strains of the G1 to G6 and G8 to G11 types. Rotavirus strain types G6 and G8, not previously recognized in pigs, were identified in field specimens of por...
متن کاملDetermination of bovine rotavirus G and P serotypes in italy by PCR.
Determination of the G and P serotypes of group A bovine rotaviruses from 149 samples of feces or intestinal contents collected from calves showing clinical signs of neonatal diarrhea was performed by a nested reverse transcription-PCR typing assay. The G6 serotype was the most prevalent, accounting for viruses in 55.7% of the samples; viruses of the G10 and G8 serotypes were found in 34.9 and ...
متن کاملDetermination of the G and P types of previously nontypeable rotavirus strains from the African Rotavirus Network, 1996-2004: Identification of unusual G types.
A total of 215 nontypeable rotavirus samples collected from children <5 years of age by members of the African Rotavirus Network were characterized using reverse-transcription polymerase chain reaction analysis and sequencing. The most predominant strain identified was P[8]G1 (46.9%). Genotypes P[8]G10, P[8]G8, P[6]G8, and P[7]G5 were also detected at frequencies varying from 0.5% to 2.3%. This...
متن کاملDetermination of bovine rotavirus G genotypes in Kashmir, India.
Rotavirus ribonucleic acid (RNA) was extracted from ten faecal samples of diarrhoeic calves positive for group A rotavirus by enzyme-linked immunosorbent assay (ELISA). A portion of the extracted RNA was run in polyacrylamide gel to determine the presence of rotaviral RNA and the rest subjected to reverse transcriptase-polymerase chain reaction (RT-PCR) to generate the near full length VP7 gene...
متن کاملMolecular characterization of G and P-types bovine rotavirus strains from Goiás, Brazil: high frequency of mixed P-type infections.
In this study, 331 samples from calves less than one month old from a dairy herd in the district of Piracanjuba, state of Goiás, Brazil were tested for rotavirus. Thirty-three samples (9.9%) tested positive for rotavirus. Out of those, 31 were submitted to G and P characterization by reverse transcription followed by semi-nested polymerase chain reaction. Two samples were characterized as G6P[1...
