摘要
目的 研究南京地区5岁及以下腹泻患儿人类杯状病毒感染的分子流行病学特点。方法2009年7月至2010年6月在南京儿童医院共采集1-59个月的腹泻患儿粪便标本300份,采用多重RT-PCR方法检测人类杯状病毒(诺如病毒、札如病毒)。结果300份标本中71份检出人杯状病毒,检出率23.67%。其中,诺如病毒67份,其中58份为GⅡ/4基因型(2006b亚型),8份为GⅡ/3基因型,1份为GⅡ/12基因型;扎如病毒4份,其中2份为GⅠ/1基因型,GⅠ/2和GⅡ/1基因型各1份。结论人类杯状病毒是南京地区腹泻婴幼儿中的主要病原体之一,主要的流行优势株是诺如病毒GⅡ/4基因型(2006b亚型)
Objective To study molecular epidemiological characteristics of human caliciviruses among infants and young children aged 0-5 years old with acute diarrhea in Nanjing. Methods Stool specimens were collected from 300 infants and young children less than 5 years old admitted with acute gastroenteritis to Nanjing Children's Hospital from July 2009 to June 2010. Human caliciviruses (including noroviruses and sapoviruses) were detected by RT-multiplex PCR. Results Human caliciviruses were identified in 71 cases from the 300 specimens and the detection rate was 23.67%. Out of these 71 positive samples, 67 cases were Norovirus including 58 of GⅡ/4 (2006b strain), 8 of GⅡ/3 and 1 of GⅡ/12; 4 cases were Sapovirus including 2 of GⅠ/1, I of GI/2 and 1 of GⅡ/1, respectively. Conclusions Human calicivirus is one of the main pathogens of diarrhea in infants and young children in Nanjing. Norovirus GⅡ/4 genotype (2006b strain) was the most predominant strain.
