High prevalence of G12 human rotaviruses in children with gastroenteritis in Myanmar

抄録

A total of human rotaviruses from 54 children with acute gastroenteritis in Myanmar in 2011 were subjected to reverse transcription-PCR to determine their G and P types. On G typing, G2 (24/54: 44.4 %) was the most prevalent, followed by G12 (17/54: 31.5%) and G1 (1/54: 1.9%). Mixed cases with G2 and G12 were found in 12 of 54 (22.2%). On P typing, P[4] was the most predominant (29/54: 53.7%), followed by P[8] (17/54: 31.5%) and P[6] (4/54:7.4%). Mixed cases with P[4] and P[8] were detected in 4 of 54 (7.4%). Thus, the detection of G2 and unusual G12 in high proportions was characteristic of human rotaviruses in Myanmar in this study setting.
