上海市肉鸽沙门氏菌的分离鉴定及流行血清型和耐药性分析
Isolation,Identification and Analysis of Serotype and Drug Resistance of Salmonella from Pigeon in Shanghai
摘要
Abstract
The purpose of this study was to investigate the molecular types and antimicrobial re-sistance of Salmonella isolated from pigeon in Shanghai from 201 1 to 2014.A total of 92 fecal samples were collected from markets.XLD plate and Salmonella chromogenic medium were used to isolate suspected Salmonella colonies,and then determined the number of Salmonella through gram staining and biochemical tests.Among them,24 (26.1%)were positive for Salmonella . Kauffmann-White method and the K-B method were used respectively for serotype identification and susceptibility testing.In result,serological identification showed that 24 isolates from pigeon could be divided into 3 serotypes including S .typhimurium (66.7%),S .agona (25.0%)and S .corvallis (8.3%).Drug susceptibility test showed that 75.0% of the isolates were resistant to one antibiotic at least.The highest level resistance were found for tetracycline as well as sulfisox- <br> azole (62.5%),followed by streptomycin (58.3%),nalidixic acid (50.0%)and ampicillin (20.8%).Multi-drug resistant strains accounted for 62.5% (15),in which the largest number of strains (7,1 6.7%)were resistant to four drugs.In addition,isolates were 100.0% susceptible to cefepime,cefotaxime,ceftazidime,imipenem and ofloxacin,but 12.5% were moderately sen-sitive to the amoxicillin/clavulanic acid and ciprofloxacin.The study showed that Salmonella had a high separation rate of pigeon in Shanghai farmers market and performed serious multidrug re-sistance,which would bring great challenges and risks to the prevention and control of Salmonel-la in food,so that the prevalence and drug resistance of Salmonella in pigeon deserved close at-tention.关键词
