“…The observation of a PFGE type with several representatives demonstrates the circulation of a single clone in the hospital and community. Previous studies have shown a higher diversity of S. warneri [ 40 ] and the dissemination of a single clone among health professionals [ 41 ]. The paucity of molecular epidemiology studies involving S. warneri hinders understanding the clonality of this species.…”

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

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 hospital and community clusters were observed. Nosocomial S. epidermidis clones belonged to sequence types ST2, ST6, and ST23. Some Staphylococcus haemolyticus clones were found to circulate in the hospital and community, while Staphylococcus saprophyticus exhibited very high clonal diversity. Staphylococcus lugdunensis, Staphylococcus warneri, and Staphylococcus capitis revealed several isolates belonging to the same clone in the hospital and community. The detection of different SCCmec types within the same cluster indicated high diversity. S. epidermidis was associated with SCCmec I and III, S. haemolyticus with I and II, S. capitis with type V, Staphylococcus hominis with mec complex type A and ccr1, and S. warneri and S. saprophyticus with SCCmec I. The generation of elements and new combinations of cassette genes were highly associated with CoNS isolates, suggesting that SCCmec may not be a good marker of clonality in these bacteria.

“…Recently, the coagulase-negative staphylococci (CNS) have been studied extensively because of their pathogenicity and involvement in some kinds of human and animal diseases (5,20,21,23). Furthermore, the strains of several CNS species (i.e., Staphylococcus epidermidis, S. haemolyticus, S. warneri, S. hominis, and S. saprophyticus) were found to have high levels of resistance to various antibiotics (25,30).…”

Distribution of Staphylococcus Species among Human Clinical Specimens and Emended Description of Staphylococcus caprae

et al. 1998

By DNA-DNA hybridization on microplates, we identified 1,230 strains of staphylococci from human clinical specimens and determined the distribution of species. The 10 Staphylococcus species isolated most often were S. epidermidis(31.3%), S. aureus (23.3%), S. haemolyticus(12.2%), S. caprae (10.7%), S. simulans(4.4%), S. hominis (4.0%), S. capitis (3.9%), S. saprophyticus (3.6%), S. warneri (2.2%), and S. lugdunensis (1.3%). From these results, we realized that S. caprae strains were widely distributed in human clinical specimens. The description inBergey’s Manual of Systematic Bacteriology indicates that no strains of S. caprae produce acid from fructose and mannitol, but all our S. caprae strains produced acid from fructose and mannitol. Consequently, many strains of S. caprae isolated from human clinical specimens have been misidentified as S. haemolyticus or S. hominis by conventional biochemical tests. In this paper, we propose an emended description of S. caprae.

“…Although S. warneri represents only 1% of the skin staphylococci in normal individuals [5], it may be associated with various human infections such as septicemia, endocarditis, meningitis, conjunctivitis, and wound infections [5]- [8]. According to previous reports, S. warneri infections were most frequently associated with indwelling devices in patients with underlying immunosuppressive illnesses [7] [8]. All postoperative patients in ICU are in high-risk conditions with indwelling catheters after severely invasive treatments.…”

Dissemination of <i>Staphylococcus warneri</i> in the Hair of ICU Doctors

This study reports a case of Staphylococcus warneri dissemination in the hair of ICU/ER doctors. Eleven of 23 doctors in the first survey and 11 of 24 doctors in the second survey, which were conducted after 6 months, carried S. warneri, while hair contamination of other coagulase-negative staphylococci was only sporadic. Chromosomal DNA analysis with PFGE revealed that 7 S. warneri strains isolated in the first survey and 7 strains isolated in the second survey showed similar PFGE patterns, suggesting that a cross-infection with a S. warneri strain continued over 6 months among the ICU doctors.
