“…The detection of AMR was performed in three reference laboratories (Fundação Alfredo da Matta, Instituto Lauro Souza Lima, and Fundação Oswaldo Cruz) that standardized the molecular technique according to WHO guidelines (29,30). The technique used is a DNA-based direct-sequencing PCR molecular test to detect mutations or single-nucleotide polymorphisms (SNPs) that have been associated with M. leprae resistance to drugs (31). The laboratories conducted the PCR for amplification of M. leprae DNA fragments isolated from a patient's skin biopsy.…”

“…Os resultados inconclusivos (22/40 -55%) ausência de multiplicação bacilar no grupo controle podem ser decorrência de uma limitação da técnica de Shepard 26 ; a alta porcentagem de resultados inconclusivos também tem sido relatada por outros autores 11 -27 " 29 . Uma outra possibilidade poderia ser a ausência de bacilos viáveis no fragmento de biópsia coletado do paciente.…”

“…A concentração de 0,01 g% corresponde, no humano, a dose de 1 OOrng. 3 Muitos anos depois, mesmo com a implantação da PQT, vários relatos de resistência secundária e primária, não somente a DDS como também a RFP, clofazimina (CLO) e ofloxacin (OFLO), foram descritos em vários países [7][8][9][10][11][12] .…”

“…Mutations associated with drug resistance have been identified for the folP, rpoB, and gyrA genes in M. leprae. As PCR testing for Mycobacterium leprae identification has been well established, routine monitoring for these mutations should be implemented during MDT surveillance and after completion of MDT [68][69][70][71][72][73][74][75][76].…”
