目的为早发现、早预警食源性疾病暴发和食品安全隐患提供科学依据。方法根据GB 4789.4—2010《食品卫生微生物学检验沙门菌检验》和GB 4789.5—2012《食品卫生微生物学检验志贺菌检验》中血清学鉴定的方法,对分离自河南省2013年腹泻病人粪便标本中的67株沙门菌和172株志贺菌进行血清学分型。结果从67株沙门菌中检出24种血清型,主要为肠炎沙门菌,所占比例为32.8%,从172株志贺菌中只检出了福氏志贺菌(B群)和宋内志贺菌(D群)2种血清型,其中又从福氏志贺菌中检出了8个亚型。在所有的型或亚型志贺菌中B2a亚型所占比例最高,为54.1%。结论河南省腹泻人群沙门菌、志贺菌血清学分布有一定的地域特征。
The purpose of early detection, early detection of foodborne disease outbreaks and food safety hazards provide a scientific basis. Methods According to the method of serological identification in GB 4789.4-2010 “Food hygiene microbiology test Salmonella test” and GB 4789.5-2012 “Food hygiene microbiology test Shigella test”, the stool samples from diarrhea patients in Henan Province in 2013 In 67 Salmonella and 172 Shigella serological typing. Results Of the 67 Salmonella strains, 24 serotypes were found, which were mainly Salmonella enteritidis (32.8%). Only Shigella flexneri (group B) and Shigella Shigella (D group) two serotypes, of which again from the Shigella flexneri detected in eight subtypes. B2a subtypes had the highest proportion of all types or subtypes of Shigella, accounting for 54.1%. Conclusions Serological distribution of Salmonella and Shigella have some geographical characteristics in Henan diarrhea population.
