Exploration of pathogenic potential Coagulase-Negative Staphylococci (CoNS), in human as well animals,gained the importance during past two decades. Emergence Methicillin-Resistant Coagulase-NegativeStaphylococci (MRCoNS) bovine milk poses to be a major public health concern. Presence mecA gene isone most common reasons reported for methicillin resistant bacteria. Since scientific data concerni...

Staphylococcus aureus (including Methicillin-resistant S. aureus) and coagulase negative Staphylococcus spp (including methicillin-resistant coagulase negative) permanently or transiently colonize humans and act as sources of complicated skin and soft tissue infections, bacteraemia and infective endocarditis. They also cause chronic infection of indwelling medical devices. Treatment of these in...

Molecular typing of twenty-five Pasteurella multocida isolates has been assessed by restriction fragmentlength polymorphism (RFLP) of a species-specific PCR assay. Amplification was based on the gene ompH, encoding a major outer memberane protein. RFLP analysis of the 1.2 kb ompH-amplification usingEcoRI, HindIII and CfoI endonucleases produced 7 different patterns for the twenty fi...

INTRODUCTION Nosocomial infections are normally hospital acquired. Nasal carriage of Staphylococcus aureus (S. aureus) is very common and may be transmitted via a hand-to-nose route. The objective of the present study was to screen healthcare workers for the colonization of their nasal cavities with MRSA. METHODOLOGY The study group included hospital staff such as nurses, doctors, and technic...

On occasion, a patient may have two or more clinical cultures yielding a coagulase-negative staphylococcus If these multiple isolates have the same phenotype, one might conclude that the same strain was reisolated from the patient, indicating its persistent and pathological presence. We examined the validity of this conclusion when we applied a number of characterizing systems to a collection o...

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,...
