| molecular genotyping of acinetobacter spp. isolated in arizona, usa, using multilocus pcr and mass spectrometry. | acinetobacter spp. are a diverse group of gram-negative bacteria frequently implicated in nosocomial infections. genotypic methods have been instrumental in studying acinetobacter, but few offer high resolution, rapid turnaround time, technical ease and high inter-laboratory reproducibility, which has hampered understanding of disease incidence, transmission patterns and diversity within this genus. here, we further evaluated multilocus pcr electrospray ionization/mass spectrometry (pcr/esi-ms), ... | 2013 | 23741021 |
