大连市零售猪肉中沙门氏菌的耐药性检测与分析
Antimicrobial Susceptibility Testing ofSalmonella in Retail Pork in Dalian City
摘要
Abstract
Objective]To investigate and understand the contamination situation ofSalmonella existed in fresh retail pork in Dalian city,as well as the drug resistance status.[Methods]78 fresh pork samples in supermarkets were collected,thenSalmonellas were isolated and purified by selective medium. After being identified by invA sequence analysis,the drug resistance of theseSalmonella isolates to 12 kinds of antibiotics was detected by the disc agar diffusion method(K-B).[Results]The results showed that 15Salmonella isolates were obtained with the detection rate of 19.23%. The resistance rate to antibiotics was in a range from 0 to 73.3%. 73.3% of the isolates were resistant toGentamycinsulfate,and the resistance rate of other antibiotics decreased in the following order:norlfoxacin hydrochloride(60%)>Florfenicol、Ciprolfoxacin Monohydrochloride(53.3%)>Amoxicillin(13.3%)>Cephalothin、Cefotaxime、Ampicillin(6.7%)>Ceftriaxone,Ceftazidime,Aztreonam,Imipenem(0),altogether 10 drug-resistance profiles were found.[Conclusion]TheSalmonella contamination was severe in the supermarkets and farmer's markets in the development zone of Dalian city,which also showed multi-resistant pattern. The results indicated sufficient attention should be paid attention to the control ofSalmonella.关键词
