Resumo: |
In recent years the number of infections caused by microbacteria non-tuberculous mycobacteria (NTM) has increased mainly due to opportunistic infections in individuals imunocompormetidos and improvement of farming techniques and identification of MTN. Mycobacterium massilienese is an emerging body associated with wound infections, abscesses and pneumonia. An outbreak of infection after videoscopy occurred between 2005 and 2007 in seven hospitals in Goiânia-GO, in central Brazil. The objective of this study was to identify NTM isolated from patients with infection after arthroscopy and lararoscopia by PCR followed by analysis of fragment length polymorphism restrção (PRA-hsp65), compared by gel electrophoresis pulsed-field gel (PFGE), sequencing of the partial rpoB gene and determination of antimicrobial susceptibility in vitro. NTM were recovered from samples (exudate abscess subcutâneio) of 18 patients involved in the outbreak. In the period leading up to this study there was no reported case of infection after videoscopy caused by MTN in Goiania. The 18 isolates were identified as M, massiliene and genotyped as a single clone, indicating that they had a common origin, suggesting a common source of infection for the patients involved in the outbreak. The epidemic isolates were susceptible to amikacin (MIC90 4 micrograms / ml) and clarithromycin (MIC90 <1 ug / ml), but resistance to ciprofloxacin (MIC90 <128g/ml), tobramycin (MIC90 32 micrograms / ml) and intermediate susceptibility to cefoxitin (MIC90 64 ug / ml). In conclusion this study demonstrated the clonality of strains of M. massiliense involved in infections after procedures videoscopes and that they are susceptible to drugs indicated for the treatment |
