MreB, the bacterial actin homologue, plays a vital role in determining cell shape, but the mechanisms by which it actually functions have remained largely mysterious. Recent studies now shed new light on MreB, demonstrating that it associates with many cell-wall synthesis enzymes, including a newly identified family of proteins that mediate teichoic acid synthesis in Gram-positive bacteria. Fur...

PURPOSE To evaluate different methods of oxacillin susceptibility testing of ocular isolates, considering polymerase chain reaction (PCR) as the 'gold standard', and to compare the in vitro susceptibility to oxacillin with that of other antimicrobials used in ophthalmologic practice. METHODS The Vitek gram-positive identification card was used to identify ocular coagulase negative Staphylococ...

M ethicillin-resistant Staphylococcus aureus (MRSA) first emerged as nosocomial pathogens in the early 1960s are of great concern to public health and highly reported in human clinical samples (1). There are major international concerns about rising levels of MRSA and multi-drug resistant S. aureus owing to the difficulties of treating infections and the ease with which MRSA spreads within hosp...

Coagulase-negative staphylococci (CoNS) represent an important etiology of nosocomial bloodstream infections (2, 4, 6). The introduction of empirical treatment has been a crucial step in reducing morbidity and mortality caused by such infections and in controlling the spread of resistant strains (1, 6). It has been advocated that the cefoxitin disk would be more sensitive than the 1g oxacillin ...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Editorial The neonatal period is the time when a human being is most vulnerable to bacterial infections such as Staphylococcus au-reus, which is a major pathogen causing neonatal morbidity and mortality. Staphylococci, aerobic or facultative anaerobic gram-p...

Pospíšil: resistance to antibiotics in Strains of Staphylococcus spp., Enterococcus spp. and Escherichia coli Isolated from rectal Swabs of Pigs. acta Vet Brno 2008, 77: 103-1100. The study aimed at determining the level of resistance of selected bacterial species (Staphylococcus spp., Enterococcus spp., E...

Staphylococcus aureus is an ubiquitous bacterium that is frequently part of the human microflora, causing disease when the immune system becomes compromized. Although S. aureus can be found in different parts of the body, anterior nares are the main ecological reservoir in humans [1]. This versatile pathogen is responsible for a wide variety of diseases, including superficial, systemic and life...

Methicillin-resistant Staphylococcus aureus (MRSA) remains one of the leading causes of nosocomial infections worldwide, although several different epidemiological lineages are now recognized. A recent emerging lineage of MRSA is livestock-associated methicillin-resistant S. aureus (LA-MRSA). First isolated from a bovine milk sample in Great Britain (1), these pathogens have now been isolated f...

Methicillin-resistant Staphylococcus aureus (MRSA), often referred to as the "deadly superbug" by the media, is currently a major epidemiological threat on a global scale. The adaptability of S. aureus to antibiotics led to the emergence of MRSA in 1961 in a hospital ward in the United Kingdom. S. aureus developed resistance to β-lactam antibiotics through the acquisition of the mecA gene, whic...

The incidence of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) continues to increase in many countries worldwide. Rapid identification of MRSA from clinical specimens and screening of high-risk patients for MRSA colonization have been found to be cost-effective measures for limiting the spread of the organism in hospitals (1, 6). Several screening media for the enhance...
