OBJECTIVE To identify the clinical variables that differentiate MRSA (Methicillin-resistant Staphylococcus aureus) from MSSA (Methicillin-sensitive S. aureus) infection. METHODS Cases having culture isolates of Staphylococcus species were recruited. Baseline and other laboratory parameters were compared between MSSA and MRSA sub-groups to identify the predictors for MRSA. RESULTS Out of 98 ...

Between January 1997 and December 1999, bloodstream isolates from 15,439 patients infected with Staphylococcus aureus and 6350 patients infected with coagulase-negative Staphylococcus species (CoNS) were referred by SENTRY-participating hospitals in the United States, Canada, Latin America, Europe, and the Western Pacific region. S. aureus was found to be the most prevalent cause of bloodstream...

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is resistant to most antibiotics and is an important pathogen of nosocomial infections. The prevalence of community (CA-MRSA) and hospital acquired methicillin-resistant S. aureus (HA-MRSA) infection is increased. In this study we investigated the frequency of MRSA colonization and its antibiotic susceptibility in students of Rafsan...

INTRODUCTION Staphylococcus aureus produces a range of virulence factors such as toxic shock syndrome toxin-1. METHODS In this cross-sectional study of 345 clinical S. aureus isolates, the presence of the tst gene was assessed by polymerase chain reaction (PCR). RESULTS The study revealed 53/345 (15.4%) isolates were positive for the tst gene. The tst gene was present in 18.1% of methicilli...

BACKGROUND Methicillin-Resistant Staphylococcus aureus (MRSA) is a major pathogen in the hospital and community settings. Rapid methods to diagnose S. aureus infections are sought by many researchers worldwide. The current study aimed to utilize a phenotypic method of turanose fermentation to identify methicillin-susceptible and resistant S. aureus. OBJECTIVES The current study aimed to assay...

Prophylactic parenteral antibiotics have contributed to the present low rate of surgical site infections following hip and knee arthroplasty. Over the past decade, there has been a change in the pattern of methicillin-resistant Staphylococcus aureus infections from hospital-acquired to community-acquired. The findings of recent studies on screening programs to identify carriers of methicillin-r...

Inmates of Rikers Island jail potentially introduce Staphylococcus aureus into New York State prisons upon transfer. In this study, methicillin-resistant Staphylococcus aureus isolates (n = 452), collected from infected inmates (2009 to 2013), were characterized. spa type t008 was the predominant clone identified, accounting for 82.3% of the isolates, with no evidence of mupirocin or chlorhexid...

Methicillin resistance in Staphylococcus aureus Staphylococcus aureus is renowned for countering almost any antibiotic challenge. Its history since the advent of penicillin is one of increasing resistance to antibiotics. Methicillin was the first semisynthetic penicillin resistant to penicillinase to be derived from the penicillin nucleus and was a major advance in the treatment of staphylococc...

Background: Staphylococcus aureus is one of the most common causes of nosocomial infections that cause a broad spectrum of diseases. Increasing antibiotic resistance among S. aureus isolates is a serious concern in the treatment and control of staphylococcal infections. The knowledge of S. aureus prevalence and the current antimicrobial resistance profile is necessary in selection of appropriat...

Staphylococcus aureus (SA or S. aureus) is a common pathogen that leads to local and systemic infections in communitarian and hospitalised patients. Staphylococcus colonizing nasal or pharyngeal sites can become virulent and cause severe infections. In this study, we collected 322 pharyngeal exudates and 142 nasal exudates from hospitalised and outpatients for screening purposes. The carriage r...
