Prevalence of three plasmid-mediated quinolone resistance determinant qnrA, qnrB, qnrS and extended spectrum Cephalosporins determinant blaCMY, among eighty-five isolates of Salmonella spp. collected in the community between 2008 and 2010 was determined by PCR. Not only qnr genes but also bla genes were positive in twenty-four different isolates. PCR assay detected that 22 of 85 (25.8%) Salmonella spp. carried the qnrA, 1 (1.17%) of 85 isolates harbored the qnrB, 1 (1.17%) of them contained the qnrS, 1 (1.17%) isolate carried all the three qnrA, qnrB, qnrS genes, 24 of 85 (28.2%) Salmonella carried blaCMY and 5 (5.88%) isolates carried qnrA and blaCMY. Antimicrobial susceptibility patterns of isolates were as follows: 49 (57.6%) exhibited resistance to Nalidixic acid and none of them to Ciprofloxacin. 33 (38.82%) isolates exhibited resistance to Cephalosporins and 2 (2.35%) of them exhibited ESBL phenotype and 12 (14.1%) isolates resistance to Ampicilin. These results were confirmed by MIC determination test as well. Having detected qnr and bla genes suggested that these genes spread antibiotic resistance among pathogenic bacteria.

老年人的泌尿道感染很常见,它给临床医师带来一系列问题。诊断所有年龄组病人的泌尿道感染均经清洁中段尿定量培养而确诊。一次培养的细菌数≥10~5/ml者有80％的感染可能性,两次尿培养的同一细菌数均为≥10~5/ml,感染可能性达95％。这... 详细信息

老年人的泌尿道感染很常见,它给临床医师带来一系列问题。诊断所有年龄组病人的泌尿道感染均经清洁中段尿定量培养而确诊。一次培养的细菌数≥10~5/ml者有80％的感染可能性,两次尿培养的同一细菌数均为≥10~5/ml,感染可能性达95％。这个统计数字对老年妇女是有异议的,Moore-Smith比较了老年住院妇女(平均79岁)中段尿和耻骨上穿刺尿培养的结果,发现30％中段尿培养阳性,而耻骨上穿刺尿仅13％阳性,故中段尿假阳性率为17％。另一些报告老年妇女中段尿定量培
