Background: Coagulase-negative staphylococci (CoNS) are commonly found in human skin as normal flora but are increasingly prevalent in hospital-acquired infec-tions, often exhibiting resistance to methicillin (MRCoNS). Vancomycin is the primary treatment for MRCoNS infections. This study aimed to assess MRCoNS pre-valence in a hospital community and evaluate Vancomycin effectiveness against MRCoNS.Methods: Swabs from 102 hospitalized surgical patients were tested before the surgery for CoNS presence.

Background. Methicillin-resistant coagulase-negative Staphylococci (MRCoNS) is regarded as the repository of mecA gene for methicillin-resistant Staphylococcus aureus (MRSA) and may develop methicillin-susceptible Staphylococcus aureus (MSSA) to MRSA. Therefore, we aimed to explore whether MRCoNS carriage is a risk factor of MRSA colonization. Phenotypic characteristics were performed to further assess the associations between MRSA and MRCoNS.

Swine farming as a source of methicillin-resistant Staphylococcus aureus (MRSA) has been well documented. Methicillin-resistant coagulase-negative staphylococci (MRCoNS) have been less studied, but their importance as pathogens is increasing. MRCoNS are indeed considered relevant nosocomial pathogens; identifying putative sources of MRCoNS is thus gaining importance to prevent human health hazards.

The article presents a comparative assessment of microbiological, clinical, and genetic aspects in patients with atopic dermatitis and ichthyosis. The results of a study in 62 patients with atopic dermatitis and 19 patients with ichthyosis showed that there was a phenomenon of persistence of opportunistic microorganisms Staphylococcus spp. in skin lesion foci. Thus, in the group of the patients with ichthyosis, the development of persistent forms of bacterial infection caused by MRCoNS is noted in 69.2 % of cases, and in the patients with atopic dermatitis, an invasive form of MRSA-associated

Coagulase-negative staphylococci (CoNS) are a group of commensal microorganisms residing on the skin and mucous membranes of both humans and animals. Until recently, they have been regarded as non-pathogenic to livestock and companion animals, but since then, their clinical importance in veterinary medicine has increased with the discovery of their potential pathogenic roles in animals causing skin and soft tissue infections together with spontaneous abortions and mastitis. Scientific data concerning the presence of CoNS in North Cyprus are very limited. Therefore, the purpose of the study rep

ABSTRACT RWJ-54428 (MC-02479) is a novel cephalosporin that binds to penicillin-binding protein (PBP) PBP 2′ (PBP 2a) of methicillin-resistant staphylococci. Its in vitro activity was assessed against 472 gram-positive cocci, largely selected as epidemiologically unrelated isolates with multidrug resistance. The MIC at which 50% of isolates are inhibited (MIC50) and MIC90 of RWJ-54428 for methicillin-resistant Staphylococcus aureus (MRSA) were 1 and 2 μg/ml, respectively, whereas they were 0.5 and 0.5 μg/ml, respectively, for methicillin-susceptible S. aureus.

CoNS are gaining importance due to increase in resistance rates to betalactam antibiotics and multi drug resistance. Although specific virulence factors are not as clearly established, it seems clear that factors such as bacterial polysaccharide components, and ability to form biofilm are involved in attachment and/or persistence of bacteria on foreign materials. Biofilms usually result in persistent infections that cannot be easily resolved with standard antibiotic treatments; therefore, the biofilm formation ability and the resistance to antimicrobial therapy can be intimately related.
