目的掌握2004—2012年北京出入境口岸食品和饲料中沙门菌的血清型分布。方法对65株分离自2004—2012年北京出入境口岸食品及饲料中的沙门菌以及13株中国医学细菌菌种保藏管理中心(CMCC)的参比菌株,共78株沙门菌进行血清分型鉴定。结果 65株沙门菌分离株中有4株沙门菌未能鉴定血清群,其他61株沙门菌分属于9个群,38个血清型,其中B群和C1群较多,分别占29.2%(19/65)和26.2%(17/65)。分离出7株阿贡纳沙门菌,占分离株的10.8%(7/65);2株肠炎沙门菌,占分离株的3.1%(2/65)。本实验室首次分离出1株斯特拉福德沙门菌。结论北京出入境口岸食品及饲料中的沙门菌血清群及血清型众多且分布广泛,开展沙门菌血清型监测,为预防北京市食源性疾病提供科学依据。
Objective To understand the serotype distribution of Salmonella in food and feed at Beijing Exit-Entry Port during 2004-2012. Methods A total of 78 strains of Salmonella isolated from Salmonella in food and feedstuffs from Beijing Port of Entry and Exit Control and 13 strains of Chinese Medical Bacterial Culture Collection (CMCC) from 2004 to 2012 were identified by serotyping . Results Four out of 65 Salmonella strains failed to identify serogroups, and the other 61 Salmonella strains belonged to 9 groups and 38 serotypes, of which, group B and group C1 accounted for 29.2% (19 / 65) and 26.2% (17/65). Seven strains of Salmonella Agaric were isolated, accounting for 10.8% (7/65) of the isolates and two strains of Salmonella enteritidis, accounting for 3.1% (2/65) of the isolates. For the first time, this laboratory isolated a Stratford salmonella. Conclusion The Salmonella serogroups and serogroups in food and feed at Beijing Exit-Entry Port are numerous and widely distributed, and the surveillance of Salmonella serogroups is carried out to provide a scientific basis for preventing foodborne diseases in Beijing.
