conclusion: the outcome of this study show that spa and coa typing are suitable meth­ods for mrsa isolates typing because it is easy to use and interpret them, and that these methods can be useful in infection source detection and its control especially in epidemic situations. result: pcr results showed seven different patterns for staff and five different patterns for patients based on spa gen...

OBJECTIVES Development of antibiotic-resistant strains of coagulase-negative staphylococci has complicated the management of infections associated with the use of invasive medical devices, and innovative treatment and prophylactic options are needed. Honey is increasingly being used to treat infected wounds, but little is known about its effectiveness against coagulase-negative staphylococci. T...

In this study, the enterotoxigenic potential of Staphylococcus strains (n = 574) isolated from raw milk samples (n = 140) was determined for their capacity to produce staphylococcal enterotoxins. In addition, the relationship between the presence of enterotoxins, coagulase, and thermonuclease (Tnase) was assessed. The results showed that 19% of Staphylococcus was enterotoxigenic, being able to ...

The coagulae-positive staphylococci comprise a very homogeneous, readily identifiable species (Evans and Niven, 1950; Shaw et al., 1951) that includes all of the proven pathogenic and enterotoxin-producing strains of staphylococci. As a result of the clinical and public health significance of these organisms, a selective medium for their isolation and enumeration would have considerable value. ...

conclusions there were diverse phenotypic changes among vancomycin-non-susceptible s. aureus isolates. this may be due to the variety of related regulatory systems. the diversity of phenotypic expression may result in its misidentification in routine laboratory checks. materials and methods a total of 130 methicillin-resistant s. aureus (mrsa) isolates were studied, including 49 vssa, 28 hvisa,...

We evaluated the Roche LightCycler Staphylococcus M(GRADE) kits to differentiate between Staphylococcus aureus and coagulase-negative staphylococci in blood cultures growing clusters of gram-positive cocci. Testing 100 bottles (36 containing S. aureus), the assay was 100% sensitive and 98.44% specific for S. aureus and 100% sensitive and specific for coagulase-negative staphylococci.

The characterization of 556 Micrococcaceae isolates from various clinical sources has been presented. The incidence of coagulase-negative mannitol-positive staphylococci was 3.2% and that of coagulase-positive mannitol-negative staphylococci was 1.6%. There appears to be insufficient justification for the routine reporting of staphylococcal variants from a general bacteriology laboratory, and b...
