Staphylococcus (S.) aureus is a common infectious agent of bovine chronic mastitis, a disease that is difficult to eradicate. The abilities of staphylococci to be internalized and form a biofilm can contribute to host immunological defence evasion that subsequently impairs antimicrobial therapy. The invasive capability of six S. aureus field isolates with different biofilmforming profiles was c...

A rapid, in situ thermonuclease test that identifies colonies of Staphylococcus aureus among staphylococci isolated from swimming pool water by membrane filtration recovery on various selective and differential media is described.

Molecular methods for the rapid identification of methicillin-resistant Staphylococcus aureus (MRSA) are generally based on the detection of an S. aureus-specific gene target and the mecA gene. However, such methods cannot be applied for the direct detection of MRSA from nonsterile specimens such as nasal samples without the previous isolation, capture, or enrichment of MRSA because these sampl...

Methicillin-resistant staphylococci (MRS), and methicillin-resistant Staphylococcus aureus (MRSA) in particular, have become a public and veterinary health concern. The search for MRS reservoirs outside human hospitals is needed in order to understand the reasons for their persistence and to control their spread. MRS have been isolated from rats, but little is known about their occurrence in fo...

Numerous investigations have attempted to define those factors responsible for the virulence of Staphylococcus aureus.'" Almost all of the enzymes and exotoxins produced by staphylococci have at some time been purported to be responsible for their pathogenicity but none has been clearly demonstrated of paramount importance.'" The relation of coagulase and alpha hemolysin to the pathogenesis of ...

Nosocomial bloodstream infections are important causes of morbidity and mortality. In this study, concurrent surveillance for nosocomial bloodstream infections at 49 hospitals over a 3-year period detected >10,000 infections. Gram-positive organisms accounted for 64% of cases, gram-negative organisms accounted for 27%, and 8% were caused by fungi. The most common organisms were coagulase-negati...

The most common pathogens in surgical site infections after total hip and knee arthroplasty are methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), and coagulase-negative staphylococci. Patients colonized with MSSA or MRSA have an increased risk for a staphylococcal infection at the site of a total hip or knee arthroplasty. Most colonized individuals who ...

BACKGROUND Dalbavancin is a long-half-life (9-12 days) glycopeptide, now in Phase 3 development. Its pharmacokinetics may facilitate home intravenous therapy, early discharge and long prophylaxis. METHODS Dalbavancin and comparators were tested in vitro against staphylococci and streptococci to determine (i) activity and (ii) the comparability of agar dilution MICs by the BSAC and the NCCLS m...

Tryptic soy broth (TSB)-grown cells of Staphylococcus aureus isolated from acute and chronic bovine mastitis bound mainly 125I-fibronectin (Fn) [corrected], whereas strains of nine species of coagulase-negative staphylococci showed a predominant interaction with 125I-collagen (Cn) [corrected] type I. A particle agglutination assay (PAA) was used to examine the interaction of coagulase-negative ...

Gram-positive cocci are common causes of bloodstream and nosocomial infections, and their multi-drug resistance is an increasingly serious problem. The present study aimed to assess the prevalence of multi-drug-resistant Gram-positive cocci in a Chinese population. In this retrospective study, data about Gram-positive cocci from in-patients (January 2006 and December 2013) at the Second Hospita...
