As part of a national rotavirus surveillance activity, we collected fecal specimens from 3,177 children with acute diarrhea in 10 regions of China between April 1998 and April 2000 and screened them for rotavirus. Rotavirus was detected in 41% (n = 1,305) of specimens, and in these, G1 was the predominant serotype (72.6%), followed by G3 (14.2%), G2 (12.1%), G4 (2.5%), G9 (0.9%), and G untypeable (0.7%). Among 327 G-typed strains tested for P genotype, 14 different P-G combinations were identified, with the globally common strains P[8]G1, P[4]G2, P[8]G3, and P[8]G4 representing 75.6% of all typed rotavirus strains. Among the uncommon strains, 11 were P[6]G9, and others included P[6]G1, P[6]G3, and five novel P-G combinations (P[9]G1, P[4]G1, P[4]G3, P[4]G4, and P[8]G2). Our results indicate that while the common rotavirus strains remain predominant, the diversity of strains is much greater than was previously recognized.
作为一项全国轮状病毒监测活动的一部分,我们于1998年4月至2000年4月期间,在中国10个地区收集了3177名急性腹泻儿童的粪便标本,并对其进行轮状病毒筛查。41%(n = 1305)的标本中检测到轮状病毒,其中G1是主要血清型(72.6%),其次是G3(14.2%)、G2(12.1%)、G4(2.5%)、G9(0.9%)和无法分型的G型(0.7%)。在327株检测P基因型的G型毒株中,鉴定出14种不同的P-G组合,全球常见毒株P[8]G1、P[4]G2、P[8]G3和P[8]G4占所有分型轮状病毒毒株的75.6%。在不常见毒株中,11株为P[6]G9,其他包括P[6]G1、P[6]G3以及5种新的P-G组合(P[9]G1、P[4]G1、P[4]G3、P[4]G4和P[8]G2)。我们的结果表明,虽然常见轮状病毒毒株仍然占主导地位,但毒株的多样性比之前认识到的要大得多。
