first detection of okp-a β-lactamase in two serratia marcescens isolates in china. | two strains of enterobacteriaceae producing prodigiosin were isolated from meat in the sichuan province of china in 2010. the strains were identified by vitek system, 16s rdna, rpob, pfs and luxs genes. minimum inhibitory concentrations were determined using the broth microdilution method. the two strains were screened for the presence of β-lactamase genes (blatem, blashv, blaokp, and blactx-m genes). based on pcr amplification and 16s rdna sequencing the analysed strains were identified as serr ... | 2011 | 22143810 |
