Summary of "Molecular Epidemiology and Resistance Profile of and Strains Isolated from Different Sources in Brazil."

The objectives of this study were to genotype a total of 48 and 39 strains isolated in Brazil from 1995 to 2016 by multilocus sequence typing (MLST) and to determine their resistance profile. The presence or points of mutation in the related resistance genes was verified. By MLST, strains were typed into 36 STs and strains were typed into 27 STs. A total of 70.8% of and 35.9% of were resistant to at least one antimicrobial tested. The gene was detected in 43.7% and in 12.8% . The gene was not detected and one presented the mutation in the 23S rRNA gene. Besides, 58.3% presented the substitution T86I in the quinolone resistance-determining region of and 15.4% presented the substitution T38I. The gene was detected in 97.9% and in 97.4% . The presence of and resistant to some antimicrobial agents of clinical use is of public health concern. The presence of STs shared between Brazilian strains and isolates of different countries is of concern since it might suggest a possible spread of these shared types.
