ABSTRACT:   The intentions of the study were to establish a reverse transcription polymerase chain reaction (RT-PCR) for G and P genotyping of rotavirus isolates and to determine the distribution of human rotavirus genotypes in Yangon. This study was done on stool samples collected from under five- year-old children admitted to the Yangon Children’s Hospital for diarrhoea in 2004. After screening for rotavirus by enzyme immunoassay (EIA), 181 stool samples (32%) were randomly chosen from 564 rotavirus positive samples, for genotyping by using RT-PCR. The rotavirus positive samples were genotyped employing multiplex RT-PCR using G and P specific primers. Genotype G3 was the most common type identified (44% of samples) followed by G1 (33.3%). The genotype G1 was the predominant type in the early part of the year, but was replaced by genotype G3 from July to December 2004. The VP7 genotypes G2, G4 and G9 each represented as minor types (total < 13% of samples). Rotavirus P genotyping was attempted in 91 samples and P genotype can be ascertained in only 31 samples of which 74.2% were identified as P(8). There was no apparent pattern of P genotype distribution throughout the year. The common P and G type combinations were G1/P(8) and G3/P (8). Several unusual G and P type combinations were also identified, two of which were G1/P (4), and one sample was G3/P (4) and another belonging to G2/P (8). The distribution of G and P genotype provides important and valuable information for the development and introduction of rotavirus vaccines, the most effective strategy for the prevention of severe rotavirus diarrhoea.
