Analysis of antibiotics resistance and virulence of multidrug resistant S. maltophilia

对采自某大学医院的66株嗜麦芽窄食单胞菌的遗传多样性、耐药谱及毒力相关酶活性的产生进行了研究。PFGE和MLST分析表明，存在各种不同的图谱。对毒力因子的研究表明，这些菌株没有很强的毒力因子。这些结果表明，所研究的临床分离株是社区获得的菌株，由于其多重耐药性而留在医院。

The diversity within the genetic and antibiotic resistance profiles and the production of virulence-associated enzymatic activities of 66 Stenotrophomonas maltophilia strains collected from a university hospital were studied. PFGE and MLST analysis indicated that there were a variety of profiles present. The study of virulence factors indicated that these strains did not have strong virulence factors. Those results suggested that clinical isolates studied were community-acquired strains and stayed in a hospital because of their multiple drug resistances.
