Representatives of the Staphylococcus genus are the most common pathogens found in hospital environments, and they are etiological agents for a large variety of infections. Various virulence factors are responsible for the symptoms and severity of infections caused by Staphylococcus aureus. Among them are staphylococcal enterotoxins (SEs), which cause staphylococcal food poisoning, and toxic sh...

We report the case of a 69-year-old female who underwent a Baerveldt implant placement for severe-stage primary open-angle glaucoma and developed a bacterial infection of the conjunctiva and abscess of the scleral patch graft with subsequent tube exposure. The infection was identified 3 weeks postoperatively and a topical antibiotic was immediately initiated. A concurrent systemic staphylococca...

The in vitro activity of WY-49605 (SUN5555) (WY) was compared with those of cefaclor, cefixime, and amoxicillin-clavulanic acid against 2,958 consecutive clinical isolates from five medical centers and 402 respiratory pathogens from 18 other facilities. Most members of the family Enterobacteriaceae were inhibited by WY (MIC at which 50% of the isolates are inhibited [MIC50], < or = 2.0 microgra...

The isolation, molecular identification and genotyping of multiresistant Staphylococcus sciuri and Staphylococcus haemolyticus from skin and soft-tissue infections are reported. Accurate and full identification of three coagulase-negative staphylococcal isolates was achieved using PCR, while the API STAPH method failed to identify an isolate of S. haemolyticus fully. The PCR assay, which detect...

Coagulase negative staphylococci are the principal cause of prosthetic valve endocarditis but are a rare cause of native valve infections. However, the incidence of native valve endocarditis is increasing. Staphylococcus capitis is a coagulase negative staphylococcus with the capacity to cause endocarditis on native heart valves. Two cases of native valve endocarditis caused by S capitis are pr...

bacteria usually cause disease in the gastrointestinal tract by colonization and growth in the gastrointestinal tract, where the micro organisms may invade the tissues of host or secretion of an exotoxin that is performed in food and then ingested by the host, examples of second group include: staphylococcal, bacillus cereus, clostridial (c.botulinum and c.perfringens type a) toxin. in this stu...

BACKGROUND Many SCCmec elements of coagulase-negative staphylococci (CoNS) could not be typed using multiplex PCR. Such a 'non-typable' SCCmec was encountered in a Staphylococcus cohnii isolate. METHODOLOGY/PRINCIPAL FINDINGS The SCCmec type of methicillin-resistant S. cohnii clinical isolate WC28 could not be assigned using multiplex PCR. Newly-designed primers were used to amplify ccrA and ...

Twenty-four Staphylococcus species and their subspecies were examined for their susceptibilities to teicoplanin by disk diffusion (30-micrograms disk) and agar dilution for the determination of MICs. Moderately susceptible and resistant clinical strains were further tested for their susceptibilities to oxacillin and vancomycin. Teicoplanin resistance was not observed in the reference strains of...

The Stethoscope— A Vector of Infection? To the Editor: In the course of investigating a hospital-wide outbreak of methicillin resistant Staphylococcus aureus, 67 physicians' stethoscopes were cultured. Both the bell and the diaphragm were sampled with a sterile cotton swab, and this was immediately streaked onto Columbia Nutrient Agar (BBL), a selective medium for grampositive organisms. The ca...
