Abstract
We subtyped Brazilian Yersinia pestis strains by pulsed-field gel electrophoresis (PFGE). This was done with 22 Brazilian Y. pestis strains: 17 from an outbreak and 5 from endemic routine surveillance. The strains were divided into 2 groups (I and II), 8 subgroups (A-H) and 19 PFGE profiles or pulsotypes. PFGE did not separate outbreak from non-outbreak strains, as identical pulsotype patterns were found among outbreak strains and strains obtained from surveillance. However, it was able to detect intraspecific genetic diversity among Brazilian strains. This PFGE technique was able to differentiate a homogeneous group of Brazilian Y. pestis strains. © FUNPEC-RP.
