High Prevalence of G12 Human Rotaviruses in Children with Gastroenteritis in Myanmar

抄録

Human rotavirus samples 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 found to be 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 the 54 (22.2%) samples. On P typing, P[4] was found to be 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%) samples. Thus, occurrence of G2 and unusual G12 in high proportions was characteristic of human rotaviruses in Myanmar in this study setting.
