Development of multiplex real-time PCR for detection of clarithromycin resistance genes for the group.

The molecular identification and its drug-resistance profile are important to choose the correct therapy. This work developed a multiplex real-time PCR (mqPCR) for detection of clarithromycin resistance genes for the group. Isolates received by Adolfo Lutz Institute from 2010 to 2012, identified by PCR restriction enzyme analysis of a fragment of the 65 gene (PRA-65) as type 1 (=135) and 2 (=71) were used.

Evaluation of drug susceptibility in nontuberculous mycobacteria using the SLOMYCO and RAPMYCO sensititre plates.

Background: Non-tuberculous Mycobacteria (NTM) cause different forms of diseases. According to recent guideline by ATS/ERS/ESCMID/IDSA, drug susceptibility test (DST) is an important requirement to choose adequate treatment. The minimum inhibitory concentration (MIC) test is the recommended method.
