摘要
目的了解内蒙古呼和浩特市2008年6月-2010年5月致婴幼儿腹泻A组轮状病毒的流行特征及病毒基因亚型特点。方法收集内蒙古妇幼保健医院<5岁全部住院腹泻患儿粪便标本730份,进行轮状病毒抗原检测,对检测阳性标本用巢式反转录聚合酶链式反应(RT-PCR)法进行分型鉴定。结果 730份标本中,酶联免疫法(ELISA法)检出阳性标本298份,阳性率为40.8%,对298份轮状病毒抗原阳性标本进行RT-PCR检测,其中G血清型分出亚型的有292份,占98.0%,P基因型分出亚型的有254份,占85.2%;同一份标本G、P分型方法均分出亚型的有250份,占83.9%,同时分出98份G亚型组合型,11份P亚型组合型。结论 G1,G3,P〔8〕是流行的优势亚型,G1+G3组合亚型又是主要的组合流行型;呼和浩特市轮状病毒感染高发季节是10月至次年2月,流行优势毒株发生了从G1到G3的漂移。
Objective To investigate epidemic characteristics and genotypes of group A human rotavirus in infants and young children with diarrhea in Hob_hot from June 2008 to May 2010. Methods Totally 730 stool specimens were collected from children under 5 years old and with diarrhea. Enzyme-linked immunosorbent assay(ELISA)was used to detect rotavirus antigen. The ELISA positive samples were detected with nest reverse transcription-polymerase chain reaction (RT-PCR) to determine the G and P genotypes of rotavirus. Results Among the samples ,298 were rotavirus antigen positive (40.8 % ) ; 292 were G genotype positive(98. 0% ) ;254 were P genotype positive(85.2% ) ;and 250 samples had G and P genotypes (83.9%). Couclusiou G1, G3 and P[ 8 ] were the predominant genotypes and G1 + G3 was the predominant mixture subtype for the epidemic of group A rotavirus in Hohhot and there was a drift of predominant genotype from G1 to G3 from 2008 to 2010.
