The density and duration of pneumococcal carriage are considered to affect the likelihood of transmission and invasive disease. Because of its importance in both spreading and causing disease, carriage has been suggested as an endpoint in future vaccine studies. Culture is the current gold standard for detection, but may not be sensitive enough to detect changes at low density. Healthy adult vo...

BACKGROUND Within the past 10 years, methicillin-resistant Staphylococcus aureus (MRSA) has not only been a hospital pathogen but also a community pathogen. To understand the carriage rate of methicillin-resistant Staphylococcus aureus (MRSA) among the adult patients visiting emergency department (ED), we conducted this study. METHODOLOGY/PRINCIPAL FINDINGS From May 21 to August 12, 2009, a t...

Infections caused by Methicillin-resistant Staphylococcus aureus (MRSA) is a growing problem. Medical students are at risk of getting infected by MRSA during their training due to exposure with infected patients and may be a source of transmission for other patients. Therefore it may be important to know nasal carriage of MRSA among medical students going for clinical posting. This prospective ...

BACKGROUND Pathogens in the nasal cavity during nasal surgery could lead to a systemic infectious condition, such as bacteremia, nosocomial infection, or toxic shock syndrome. However, there is no research about the prevalence of nasal carriage in patients with nasal bone fracture. METHODS This was a prospective, double-blind, randomized study about the rate of nasal carriage in 200 patients ...

Two topical MRSA eradication regimes were compared in hospital patients: a standard treatment included mupirocin 2% nasal ointment, chlorhexidine gluconate 4% soap, silver sulfadiazine 1% cream versus a tea tree oil regimen, which included tea tree 10% cream, tea tree 5% body wash, both given for five days. One hundred and fourteen patients received standard treatment and 56 (49%) were cleared ...

PURPOSE Staphylococcus aureus is a common cause of invasive infections, yet most assessments of prevalence are based on health care-based samples. We computed population-based estimates of nasal carriage of S aureus and risk factors for carriage, as well as population-based estimates of nasal carriage of methicillin-resistant S aureus (MRSA). METHODS We used the National Health and Nutrition ...

The nasal carriage of Staphylococcus aureus in 808 Australian medical students was studied. Five groups of students experienced varying degrees of clinical exposure in a hospital environment ranging from 0 to 42 months. The overall percentage of carriers among the five groups did not vary. However, with increasing clinical exposure there was a decrease in the percentage of isolates sensitive to...

OBJECTIVES Determining Staphylococcus aureus nasal carriage, antibiotic susceptibility and association with potential risk factors in residents from the Hogar Asilo de Ancianos San Pedro Claver nursing-home in Cartagena during the second semester of 2007. METHODS Nasal swabs were taken from each person participating in the study after they had signed an informed consent form. Staphylococcus a...

BACKGROUND So far it remains unclear what the optimal screening method for detection of S. aureus nasal carriage in patients on haemodialysis is with regard to number of cultures performed, culture interval, and necessity of a broth-enrichment procedure. METHODS A prospective, uncontrolled study was performed at the renal unit of a tertiary care centre, including all haemodialysis patients (n...
