Staphylococcus aureus subsp. aureus ATCC 25923 is commonly used as a control strain for susceptibility testing to antibiotics and as a quality control strain for commercial products. We present the completed genome sequence for the strain, consisting of the chromosome and a 27.5-kb plasmid.

The CLSI M100-S19 document has recommended the disuse of vancomycin disks for staphylococci and informed that studies on the action of teicoplanin in disk-diffusion testing should be performed. We describe the comparison of two methods, disk diffusion and broth microdilution, for determining teicoplanin susceptibility in clinical isolates of staphylococci. Overall results showed an aggregation ...

One thousand and thirty-five clinical isolates of the genus staphylococcus were used to compare the coagulase test with the deoxyribonuclease (DNase) and heat-stable nuclease tests as methods for identifying Staphylococcus aureus. Conflicting results were obtained with 65 isolates when the coagulase test was compared with the DNase test but with only one isolate when the coagulase test was comp...

conclusions the remarkable rates of biofilm production ability among clinically isolated staphylococci emphasize the necessity of more effective infections control policies to prevent biofilm formation on medical devices and hospital environmental surfaces. background biofilm formation capacity is recognized as an important virulence factor in staphylococci that makes the organisms more resista...

background and objectives: staphylococcus aureus is an important agent in hospital and community-associated infections, causing high morbidity and mortality. introduction of the new antimicrobial classes for this pathogen has been usually followed by the emergence of resistant strains through multiple mechanisms. for instance, resistance to clindamycin (cli) can be constitutive or inducible. in...

background staphylococcus aureus is a major pathogen in hospital setting and in the community and causes a wide range of diseases. mrsa infection has recently become a serious problem in anti-microbial chemotherapy. the aim of the study was to detect and analyze the antibiotic diversity and isolation of methicillin resistance gene (meca) of s. aureus isolated from tehran hospitals as a rapid an...
