| antimicrobial susceptibility of bacteroides fragilis group organisms in hong kong by the tentative eucast disc diffusion method. | this study used a recently developed eucast disc diffusion method to measure the susceptibility of 741 b. fragilis group isolates to six antibiotics. isolates nonsusceptible to imipenem and metronidazole by the disc method were further investigated by e-test. species identification was obtained by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (maldi-tof ms), pcr assays and 16s rrna sequencing. the most common species were b. fragilis (n = 424, including 81 division ... | 2017 | 28414107 |
