background and objectives: macrolide, lincosamide and streptogramin b (mlsb) antimicrobial agents are widely used in the treatment of staphylococcal infection. clindamycin is the medicine of choice for some staphylococcal infections, particularly skin and soft tissues infections. erythromycin and clindamycin are two distinct classes of antimicrobial agents which inhibit protein synthesis in bac...

Staphylococci are common causes of healthcare-associated and community-associated infections. However, limited data are available on the prevalence, phenotypes and molecular characteristics of Staphylococci in metro system around the world. 320 surface samples were collected from the Guangzhou metro system to isolate and characterize Staphylococci strains. Of the samples, 75.6% (242/320) were c...

BACKGROUND AND OBJECTIVES Methicillin resistance Staphylococcus aureus (MRSA) and coagulase negative staphylococci (MRCoNS) have recognized as the major cause of nosocomial infections that threat the burn patient's life. The aims of this study were to determine the frequency of MRSA and MRCoNS and their antibiotic resistance patterns among burn patients in a burn center in Ahvaz, Iran. MATERI...

The presence, distribution and antibiotic profile of staphylococci was determined in River Ganga in Uttarakhand region (India). A total of 128 staphylococcal strains were obtained from 32 sites which corresponded to three species namely S. aureus, S. hominis and S. aegilis. S. aureus dominated the staphylococcal population comprising of 68.75% of the total staphylococci. The sensitivity of stap...

staphylococci isolated from 98 mastitic cow’s milk samples were analyzed for the production of alpha,beta and delta-hemolysin on sheep, bovine and horse red blood cells and in vitro susceptibility to several antimicrobial agents. out of a total of 18 isolated strains, 100% demonstrated hemolytic activity either alone or in combined forms. among 8 isolates of s. aureus 3 isolates produced α/β an...

BACKGROUND Staphylococcus aureus strains that are Panton-Valentine leukocidin (PVL) positive cause severe skin and soft tissue infections as well as necrotizing pneumonia. The presence of PVL gene is a marker for methicillin-resistant S. aureus; therefore, survey on prevalence and phylogenetic distribution of PVL is of great importance for public health. The aim of this research was molecular e...

conclusions fortunately, due to its lower virulence as compared to its cousin s. aureus, pji due to cons may display higher remission rates than s. aureus-caused pji after combined surgical and medical management. results the main differences between the pathogens lie in the clinical presentation of pji, the presumed origin of infection, and the presence of a higher proportion of methicillin-re...

Staphylococci and streptococci are leading causes of healthcare community-acquired bacterial infections worldwide. Within each genus, virulent species such as Staphylococcus aureus, Streptococcus pyogenes pneumoniae associated with diverse syndromes superficial infection, invasive infection exotoxin production. less coagulase-negative staphylococci viridans common harmless human commensals but ...

1 2 The cell surface-associated extracellular adherence protein (Eap) mediates adherence of 3 Staphylococcus aureus to host extracellular matrix components, and inhibits inflammation, 4 wound healing and angiogenesis. A well-characterized collection of S. aureus and non5 S. aureus staphylococcal isolates (n = 813) was tested for the presence of the Eap-encoding 6 gene (eap) by PCR to investigat...

Vitek 2 (bioMérieux, Inc., Durham, NC) is a widely used commercial antimicrobial susceptibility testing system. We compared MIC results obtained by Vitek 2 to those obtained by the Clinical and Laboratory Standards Institute (CLSI) broth microdilution (BMD) reference method for 134 staphylococcal and 84 enterococcal clinical isolates. Nineteen agents were evaluated, including all those availabl...
