Plesiomonas shigelloides exports a lethal cytotoxic-enterotoxin (LCE) by membrane vesicles
Braz. j. infect. dis; 20 (6), 2016
ABSTRACT Plesiomonas shigelloides isolated from water in Brazil was previously described as a hemorrhagic heat-labile cytotoxic-enterotoxin producer. We purified this toxin from culture supernatants using ion metallic affinity chromatography (IMAC) followed by molecular exclusion chromatography. The pure...

Local circulating clones of Staphylococcus aureus in Ecuador
Braz. j. infect. dis; 20 (6), 2016
ABSTRACT The spread of pandemic Staphylococcus aureus clones, mainly methicillin-resistant S. aureus (MRSA), must be kept under surveillance to assemble an accurate, local epidemiological analysis. In Ecuador, the prevalence of the USA300 Latin American variant clone (USA300-LV) is well known; however, t...
