Isolation,Identification and Drug Resistance Analysis of Salmonella Mastitis from Dairy Cows in Urumqi Area
In order to understand the prevalence and drug resistance of Salmonella mastitis in dairy cows in the surrounding areas of Urumqi,this study collected 300 milk samples of dairy cows with mastitis from 5 farms,isola-ted and cultured Salmonella,identified by fluorescent PCR method,and analyzed the drug resistance of the positive strains by disk diffusion method.The results showed that 12 strains of Salmonella were isolated from milk cow mas-titis samples,and the isolation rate was 4%.The drug resistance analysis showed that the resistance rate of isolated Salmonella to ampicillin,tetracycline,doxycycline and streptomycin was over 50%,and the sensitivity to amtro-nam,norfloxacin,polymyxin B and ceftazidme was over 70%.In addition,four Salmonella isolates were multidrug resistant.This study provided the basis for the prevention and treatment of cow mastitis in this area.
