Analysis of nosocomial Staphylococcus haemolyticus by MLST and MALDI-TOF mass spectrometry.

Coagulase-negative staphylococci (CoNS) are a major component of normal human skin and mucosae flora. However, some species of CoNS can lead to infections in immunocompromised patients and premature newborns. The choice of a rapid and reliable typing method is one of the major problems in the epidemiological monitoring of CoNS, especially Staphylococcushaemolyticus isolates.
