Molecular typing and characterization of macrolide, lincosamide and streptogramin resistance in Staphylococcus epidermidis strains isolated in a Mexican hospital.

Staphylococcus epidermidis is a normal commensal of skin that has become a serious clinical problem because of the combination of increased use of intravascular devices and an increasing number of hospitalized immunocompromised patients. In addition, there is a lack of information pertaining to resistance to macrolide, lincosamide and streptogramin type B (MLS(B)) in developing countries, including Mexico. The aim of this study was to investigate the incidence of resistance to MLS(B) antibiotics in isolates of S.

[Molecular study of methicillin-resistant Staphylococcus haemolyticus in a Mexican hospital].

Objective: To perform the molecular characterization of methicillin-resistant Staphylococcus haemolyticus (MRSH) clinical isolates from patients in a Mexican hospital.

Methods: Sixty three Staphylococcus ssp. isolates collected from September 2000 to October 2002 were analyzed.
