Serotypes end virulence markers of Shiga toxin-producing Escherichia coli (STEC) isolated from dairy cattle in Sa˜o Paulo State, Brazil. Serotype diversity as drawback in

Upon analysis of PFGE patterns of the 12 MRSA strains isolated from blood cultures, 8 different patterns were observed, 9 (75%) strains were genetic related to nasal secretion

The aims of this work were to evaluate the genetic diversity of 45 type Ia GBS strains isolated in Brazil by pulsed-field gel electrophoresis as well as to evaluate

On the other hand, it has been observed that strains with the same PFGE (pulsed field gel electrophoresis) pattern or belonging to the same clonal group showed differences in
