Coagulase-Negative Staphylococci Clones Are Widely Distributed in the Hospital and Community

Abstract: Coagulase-negative staphylococci (CoNS) may be considered contaminants when isolated from clinical specimens but may also be a cause of true infection. This study aimed to compare the clonality and SCCmec type of a collection of CoNS isolated from blood cultures of inpatients, nasal swabs of healthy individuals, and patients with chronic wounds, all from the same community, using SCCmec typing, pulsed-field gel electrophoresis (PFGE), and MLST. Staphylococcus epidermidis, exhibited high clonal diversity, but h… Show more

“…Warneri is a coagulase-negative Staphylococcus (CNS) commonly present in human mucous membranes and epithelial microbiota. This microorganism has been considered a potential new pathogen in non-oral severe infections [ 36 , 37 ]; but has rarely been studied in periodontology. The epidemiology and the pathogenesis of S. warneri are still unclear [ 38 , 39 ].…”

“…S. epidermidis is part of the normal human flora, predominantly colonizing the adult skin [ 20 ], and on many occasions it is wrongly identified as a contaminant, despite causing many serious infections [ 14 ]. In recent years, it has become an important opportunistic pathogen causing nosocomial infections, and it tends to be multidrug-resistant [ 18 ].…”

“…In recent years, CoNS have attracted a lot of attention as pathogenic causes of infections in humans—particularly in immunocompromised, critically ill, or long-term hospitalized patients, and those with invasive medical devices, such as catheters. They have been connected to infections such as urinary tract infections, bloodstream infections, and infections caused by intrusive devices [ 14 ]. While distinguishing between harmless and pathogenic CoNS remains challenging, breakthroughs in diagnostic methods have increased our understanding of pathogenicity’s molecular mechanisms.…”

“…S lugdunensis has been identified in regions of the body rich in apocrine glands and has recently been implicated in infections in both healthy and immunosuppressed individuals. 5 Several studies have explored the relationship between skin flora composition and hidradenitis suppurativa. Guet-Revillet and colleagues 4 classified patients into 2 profiles: one of mixed anaerobes and another of S lugdunensis.…”
