Speciation and Detection of Virulence Factors of Coagulase Negative Staphylococci Isolated from Various Clinical Samples

Coagulase negative Staphylococci (CoNS), more commonly accounted as contaminants are now considered as a important potential pathogens with increase in use of implants and with the increase in frequency and number of severely debilitated patients. More than 30 species of CONS are recognised but only a few are commonly incriminated in human infections. Although CoNS were long considered nonpathogenic and having few virulence factors, new factors have lately been determined in the period of gradual clarification of pathogenesis. The majority of known factors are incorporated into the biofilm formation (Longuaerova, 2006). Production of biofilm by coagulase negative Staphylococci especially in higher incidence by S.
