BACKGROUND Clinical significance of Staphylococcus aureus colonization has been demonstrated in hospital settings; however, studies in the community have shown contrasting results regarding the relevance of colonization in infection by community-associated MRSA (CA-MRSA). In Colombia there are few studies on S. aureus colonization. The aim of this study was to determine the molecular and epidem...

coagulase-negative staphylococci (cons) have been identified as a major cause of nosocomial infections. nasal carriage of cons in nurses and physicians is known to be an important risk factor for potential hospital infections. this study was carried out to investigate the prevalence of nasal carriage of uncommon coagulase-negative staphylococci among nurse and physician staffs of tehran univers...

Staphylococcus aureus and MRSA are important clinical pathogens representing a serious public health problem. This study aimed to determine the prevalence of S. methicillin-resistant (MRSA) nasal carriage among dental students, identify factors that influence this carriage, characterize MRSA. A 25.2% 0.86% was estimated, respectively, SCCmec Type VI, identified in all isolated The low colonizat...

Nasal carriage of Staphylococcus aureus represents a well-defined factor of risk involving community and hospital-acquired infections. Recently a significance of several host factors has been pointed out and, in particular, of immune determinants in nasal S. aureus colonization. Therefore, this study aimed at analysis of manifestation involving manifestation in the nasal secretions of important...

Nasal colonization of Methicillin-resistant Staphylococcus aureus (MRSA) is a potential source spread and prerequisite for staphylococcal infections. MRSA colonization, which causes infection in people living with HIV (PLWHIV), could lead to longer hospital stay, increased medical costs, prolonged antibiotic administration. This study aims determine the nasal rate, associated risk factor...

Objective Analyze nasal colonization by oxacillin-sensitive and oxacillin-resistant Staphylococcus aureus in people with HIV/AIDS (PWHA) at days 1 and7 of hospitalization. METHOD A prospective observational study conducted in a hospital in the countryside of the state of São Paulo. Nasal swab samples were collected and analyzed through microbiological identification, at days 1 and 7 of hospit...

objective one of the prominent microorganisms in several reports of nosocomial infections is staphylococcus aureus (s. aureus) which is carried by several health care workers (hcw) many times throughout the day. the present investigation was conducted to assess the nasal and hand carriage rate of s. aureus amongst medical personnel of loghman hakim hospital's toxicological intensive care unit (...
