Title: Etiological survey of acute gastroenteritis caused by Norovirus
Abstract: Objective To investigate the main pathogens of acute gastroenteritis outbreak in Tianjin. Methods Stool and well water samples were collected to detect viruses by real-time PCR and RT-PCR. Viruses detection included rotavirus(A, B, C group), Norovirus(GⅠ, GⅡ), sapovirus, adenoviruses and astrovirus. The enteropathogenic becteria were detected in feces at the same time. Sequence analysis was conducted on the positive samples. Results A total of 33 feces specimens were collected from acute gastroenteritis cases. Norovirus GⅠ was present in 15.2 %, GⅡ in 36.4 %, both GⅠ and GⅡwere present in 9.1%. The sequences of the viruses detected from the stool samples of the patients belonged to the norovirus G Ⅰand GⅡ.One strain of GⅠ belonged to GⅠ/14. Among four strains of GⅡ,two belonged to GⅡ/8, one belonged to GⅡ/6, one belonged to GⅡ/2. No rotavirus(A, B, C group), sapovirus, adenoviruses, astrovirus and enteropathogenic becteria were detected. Three well water samples were acute gastroenteritis viruses-negtive. Conclusion This gastroenteritis outbreak was caused by norovirus GⅠ and GⅡ.
