MARTINEZ, PEDRO  y  MATTAR, SALIM. Posible clinical isolate of Staphylococcus cohnii resistant to vancomicyn. Infect. [online]. 2006, vol.10, n.3, pp.175-177. ISSN 0123-9392.

Staphylococcus cohnii, commonly found on the skin and in the gastrointestinal tract of healthy people, occasionally can cause community and hospitalacquired infections. In 1987 coagulase-negative Staphylococcus resistant to vancomycin was reported. Since then coagulase-negative Staphylococci isolates resistant to vancomycin have been reported. This report describes the possible first S. cohnii isolate resistant to vancomycin (MIC = 64 µg/ ml) in Colombia, from a pleural liquid obtained from a 5 year old patient with pleural empyema, pneumonia, and sepsis. Besides, this report describes the failure to detect vancomycin-resistant Staphylococci spp. by semi-automated susceptibility and disk diffusion methods.

Palabras clave : Staphylococcus cohnii; pleura; pneumonia; bacteremia; resistence; vancomicin.
