| identification of nontuberculous mycobacteria in clinical samples using molecular methods: a 3-year study. | nontuberculous mycobacteria (ntm) are being increasingly isolated in clinical laboratories and present technical and therapeutic challenges. in the present study, we report our experience with the identification of ntm received from 12 lisbon hospitals over a 3-year period using genotype mycobacterium (cm/as) assays (hain lifescience gmbh, nehren, germany). together, the two kits identified 96.6% of all ntm isolates tested. among the 18 ntm species identified, mycobacterium avium complex was the ... | 2010 | 19832711 |
| resistance to bacitracin in streptococcus pyogenes from oropharyngeal colonization and noninvasive infections in portugal was caused by two clones of distinct virulence genotypes. | during 2000-2007 in lisbon, we identified 45 bacitracin-resistant streptococcus pyogenes isolates among 1629 isolates: 24 from oropharyngeal healthy carriers (out of 1026), 21 from patients with noninvasive infections (out of 559) and zero from invasive infections (out of 44). forty-four of those isolates, mainly of colonization, are low-level bacitracin-resistant members of the cmls(b)-macrolide-resistant and tetracycline-susceptible emm28/st52 clone previously detected in europe, but only amon ... | 2009 | 19486163 |
