| association between the cfxa gene and transposon tn4555 in bacteroides distasonis strains and other bacteroides species. | the bacteroides genus, the most prevalent anaerobic bacteria of the intestinal tract, carries a plethora of the mobile elements, such as plasmids and conjugative and mobilizable transposons, which are probably responsible for the spreading of resistance genes. production of beta-lactamases is the most important resistance mechanism including cephalosporin resistance to beta-lactam agents in species of the bacteroides fragilis group. in our previous study, the cfxa gene was detected in b. distaso ... | 2007 | 17486409 |
