Investigation of Drug Resistance of Escherichia coli Isolated from Sika Deer in Shandong and Jilin Provinces
The drug resistance and drug-resistant genes of Escherichia coli(E.coli)isolated from sika deer in Shandong and Jilin Province were investigated.A total of 29 E.coli strains(96.67％)were isolated from 30 fecal samples of sika deer in Shandong and Jilin Province,and the minimum inhibitory concentration(MIC)of the isolated strains was determined.The results revealed varying degrees of drug resistance among the isolates,with multi-drug resistant strains accounting for 48.28％to more than three drugs,with a resistance rate exceeding 50％to tetracycline,ampicillin,etc.Moreover,quinolones qnrS,tetracyclines tet(A),and β-lactam blaTEM resistance genes were detected at rates above 50％,with qnrS being detected as high as 86.21％.Notably,both the drug resistance rate and detection rate of drug-resistant genes in Jilin Province surpassed those in Shandong Province.
