Toxigenicity in Staphylococcus aureus and Coagulase-Negative Staphylococci: Epidemiological and Molecular Aspects
Representatives of the Staphylococcus genus are the most common pathogens found in hospital environments, and they are etiological agents for a large variety of infections. Various virulence factors are responsible for the symptoms and severity of infections caused by Staphylococcus aureus. Among them are staphylococcal enterotoxins (SEs), which cause staphylococcal food poisoning, and toxic sh...
متن کاملMethicillin-resistant Staphylococcus aureus and methicillin-resistant coagulase-negative staphylococci from conjunctivas of preoperative patients.
To evaluate the incidence and characteristics of carriers of conjunctival methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococci (MRCNS) among preoperative patients at an eye clinic, bacterial growth was studied in 978 conjunctival specimens of 628 preoperative patients without signs of ocular infection. Specimens were evaluated for growth ...
متن کاملAntibiotic Resistance of Staphylococcus Aureus and Coagulase-negative Staphylococci Isolated from Bovine Mastitis
The antibiotic susceptibility test was carried out on 103 Staphylococcus aureus and 136 coagulase-negative staphylococci (CNS) strains. Only 35 of the isolates were susceptible to all antibiotics tested, while the remaining 204 isolates were resistant at least to one of the antibiotics. Among staphylococci, 18 isolates of S. aureus and 31 isolates of CNS were found phenotypically resistant to m...
متن کاملDiversity and evolution of blaZ from Staphylococcus aureus and coagulase-negative staphylococci.
OBJECTIVES To elucidate the diversity and evolutionary history of plasmid- and chromosomally-located blaZ, to detect indications of frequent exchange of blaZ between human and bovine staphylococci and to estimate the frequency of transfer of blaZ between coagulase-negative staphylococci (CoNS) and Staphylococcus aureus of bovine origin. METHODS blaZ was detected in 143 strains of penicillin-r...
متن کاملRegulation of agr-dependent virulence genes in Staphylococcus aureus by RNAIII from coagulase-negative staphylococci.
Many of the genes coding for extracellular toxins, enzymes, and cell surface proteins in Staphylococcus aureus are regulated by a 510-nucleotide (nt) RNA molecule, RNAIII. Transcription of genes encoding secreted toxins and enzymes, including hla (alpha-toxin), saeB (enterotoxin B), tst (toxic shock syndrome toxin 1), and ssp (serine protease), is stimulated, while transcription of genes encodi...
