Isolation,Identification and Antibiotics Sensitivity of Intestinal Salmonella of Non-human Primates

A total of 384 fecal samples were collected from 13 zoological gardens and examined for intestinal Salmonella.153 strains of Salmonella were isolated and identified by series of tests,including isolation of bacteria,biochemical tests,etc.The separation rate was 39.84%.According to the CLSI,antimicrobial susceptibility test,against 22 kinds of common antibiotics and other antibiotics,was carried out for the 153 strains of Salmonella.Our results indicated that the 153 strains of Salmonella showed varying degrees of drug resistance.They were of the highest resistance to carbenicillin(drug resistance rate,95.42%).They had the highest sensitivity to imipenem(sensitivity rate,90.20%).The phenomenon of multiple drug resistance occurred in all strains of Salmonella.One of these strains was resistant to 18 kinds of antibiotics.123 strains,80.39% of all strains isolated,were indentified to be resistant to 2 to 12 kinds of antibiotics.Variance analysis of resistance to 22 kinds of common antibiotics was conducted,and the results suggested that there were differences in drug resistance among the Salmonella strains collected from 13 zoological gardens.
