It has generally been accepted that enterotoxin production is confined to coagulase-positive staphylococci, although the isolation of enterotoxigenic coagulase-negative strain has been reported. 1.2.3.4 Coagulase-positive staphylococci which produce enterotoxins have been found in 96.2 percent, 5 92 percent, 6 44 percent, 7 or 95 percent 8 of the strains isolated from food products involved in ...

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...

Seventeen patients with endophthalmitis due to coagulase-negative staphylococcus were treated over a nine-year period with vitrectomy, intraocular antibiotics, and systemic steroids and antibiotics. Fifteen patients presented with moderate to severe disease and visual acuities from counting fingers to light perception, while two had acuities of 20/60 and 20/200. A final visual outcome of 20/70 ...

Coagulase negative staphylococci (CNS) were a rare cause of native valve endocarditis. However, they are emerging as an important cause of native valve endocarditis (NVE) in both community and healthcare settings. We describe a 64 yrs. old male who developed mitral valve endocarditis caused by coagulase negative staphylococci. There were no predisposing conditions or underlying cardiac disease ...

Staphylococcus aureus and coagulase-negative staphylococcal isolates from various geographic areas in the United States were examined by using a conjugative transfer gene DNA probe in dot-blot hybridization assays. Of 175 S. aureus isolates, 47 (27%) hybridized with the probe, while 24 of 208 (11.5%) coagulase-negative staphylococci hybridized. However, among methicillin-resistant S. aureus 52%...

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 ...

A total of 183 coagulase negative Staphylococcal infected quarters and 64 uninfected quarters were randomly allotted to 4 experimental groups: infected quarters that did not receive any treatment (positive control group; n = 60); infected quarters that received Tylosin (n = 61) or Cefquinome (n = 62) and also uninfected quarters that did not receive any treatment were considered as negative con...
