Última The accessory gene regulator (agr) controls Staphylococcus aureus virulence in a murine intracranial abscesses model BJID Gong,Jian; Li,Dongzhi; Yan,Jun; Liu,Yu; Li,Di; Dong,Jie; Gao,Yaping; Sun,Tao; Yang,Guang. Background:Intracranial abscesses are associated with high mortality. Staphylococcus aureus is one of the main pathogens that cause intracranial infection. Until now, there is no report to identify the key effectors of S. aureus during the intracranial infection.Methods:The murine intracranial abscesses model induced by S. aureuswas constructed. The vital sign and survival rate of mice were observed to evaluate the infection. Histological examination was used to diagnose the pathological alterations of mouse tissues. The sensitivity of S. aureus to whole blood was evaluated by whole-blood killing assay.Results:In murine intracranial abscesses model, it was shown that the mortality caused by the accessory gene regulator (agr) locus deficient strain was...

Methicillin-Resistant Staphylococcus aureus (MRSA) is responsible for an increasing number of serious hospital and community acquired infections. Virulence gene expression in Staphylococcus aureus is orchestrated by regulators such as the accessory gene regulator (agr). Staphylococcal strains are divided into four major agr groups (agrI-IV) on the basis of agrD and agrC polymorphisms. The purpose of this study was to define the prevalence of MRSA strains in appointed Tehran's hospitals and then to define and compare the proportion of agr I, II, III, IV polymorphisms between MRSA and Methicillin Sensitive Staphylococcus aureus (MSSA) strains. A total of 235 isolates were evaluated by conventional antibiotic susceptibility tests and PCR for agr and mecA...
