Genotyping methods and their contributions to the study of tuberculosis dynamic...
Castillos De Ibrahim Das Neves, Yasmin; Reis, Ana Julia; Xavier Maio, Nathália; Vianna, Júlia; Perdigão, João; Bastos Ramis, IvyIntroduction: Mycobacterium tuberculosis genotyping has impacted evolutionary studies worldwide. Nonetheless, its application and the knowledge generated depend on the genetic marker evaluated and the detection technologies that have evolved over the years. Here we describe the timeline of main genotypic methods related to M. tuberculosis in Latin America and the main findings obtained. Methodology: Systematic ...
Spread of Mycobacterium tuberculosis in Southern Brazilian persons deprived of ...
Busatto, Caroline; Possuelo, Lia Gonçalves; Bierhals, Dienefer; de Oliveira, Carolina Larrosa; de Souza, Mariana Quaresma; Fanfa, DandaraTo evaluate the genetic diversity and clustering rates of M. tuberculosis strains to better understand transmission among persons deprived of liberty (PDL) in Rio Grande do Sul (RS), southern Brazil. This is a cross-sectional study, including strains of M. tuberculosis isolated from PDL, stored at the Central Laboratory of RS, in the period from 2013 to 2018. The molecular characterization was performed using t...
