Detecção de mutações relacionadas a droga resistência no gene gyrB do Mycobacterium leprae
Detection of mutations related to drug resistance in the gyrB gene of Mycobacterium leprae

No Mycobacterium leprae (M. leprae) a resistência aos antimicrobianos dapsona (DDS), rifampicina (RIF) e ofloxacina (OFLO) se dá, primariamente, pela ocorrência de mutações em sequências conservadas dos genes folP1, rpoB e gyrA. Na rotina do Instituto Lauro de Souza Lima, muitos pacientes que apr...

Oseltamivir-resistant influenza A(H1N1)pdm2009 strains found in Brazil are endowed with permissive mutations, which compensate the loss of fitness imposed by antiviral resistance

Mem. Inst. Oswaldo Cruz; 110 (1), 2015
The 2009 pandemic influenza A virus outbreak led to the systematic use of the neuraminidase (NA) inhibitor oseltamivir (OST). Consequently, OST-resistant strains, carrying the mutation H275Y, emerged in the years after the pandemics, with a prevalence of 1-2%. Currently, OST-resistant strains have been f...
