Screening for methicillin-resistant Staphylococcus aureus (MRSA) carriage in patients at risk was evaluated as part of a control program in a 26-bed medical intensive care unit (ICU) of a university hospital with a high level of endemic MRSA. Control measures included isolation and barrier precautions, skin decolonization with chlorhexidine of patients from whom MRSA was recovered, and mupiroci...

Methicillin-resistant Staphylococcus aureus (MRSA), known as a nosocomial pathogen, has been isolated from community-acquired infections since the 1980s. It has been reported that there are carriers of MRSA in the community although the rate of carriers is low and the most important risk factor of community-acquired carriage is hospitalization or referral to healthcare facilities. We attempted ...

S. aureus is a frequent cause of infections both in hospital setting and outside it. The growing resistance of this pathogen to beta-lactam and other antibiotics complicates the treatment. The aim in this study was to investigate the frequency of nasal carriage of S. aureus among healthy population who can be the source of infection, as well as a share of MRSA colonisation. We analyzed 5.776 th...

background: methicillin resistant staphylococcus aureus (mrsa) nasal carriers play role in development of nosocomial infections and may increase treatment costs and mortality rate. these isolates, in addition to beta lactamase, is resistant to other drugs. carrier frequency and spectrum awareness of drug sensitivity in these isolates will be useful in choosing more effective methods of control ...

background staphylococcus aureus is a major nosocomial pathogen world wide. mupirocin plays a crucial role in strategies designed to control outbreaks of s. aureus. objectives the aim of this study was to determine the frequency of mupirocin resistance in s. aureus strains isolated from nasal carriers among the hospitalized patients at kermanshah hospital, iran. patients and methods a total of ...

BACKGROUND Residents in nursing homes (NHs) always represent potential reservoirs for Staphylococcus aureus and methicillin-resistant S. aureus (MRSA). To our knowledge, there is no epidemiological information up till now that describes the prevalence and molecular characteristics of S. aureus in nursing home residents in Shanghai, China. METHODS Four hundred and ninety-one unique residents f...

BACKGROUND There is a critical need for an effective Staphylococcus aureus vaccine for the prevention of staphylococcal disease. In this study, we investigated the impact of S. aureus conjugate vaccine comprised of capsular polysaccharides 5 and 8 (CP5, CP8) on nasal colonization with S. aureus. METHODS Healthy adults recruited from one academic medical center to participate in a lot consiste...

BACKGROUND People working with pigs are at elevated risk of harboring methicillin resistant S. aureus (MRSA) in their nose, which is attributable to occupational exposure to animals harboring livestock adapted S. aureus. To obtain insight into the biological nature of occupationally related nasal culture positivity, we conducted a longitudinal study of 66 swine veterinarians in the USA. METHO...

background methicillin -resistant staphylococcus aureus (mrsa) is associated with serious infections. having the ability of biofilm-formation decrease their susceptibility to antibiotics. objectives the aim of this study was to determine the prevalence of biofilm formation among mrsa isolated from nasal carriers in the beheshti teaching hospital in kashan, iran. materials and methods a cross-se...

results fifty-three (53%) isolates were simultaneously resistant to erythromycin, azithromycin and clarithromycin (cross-resistance); while 8 (8%) isolates had variable macrolide susceptibility pattern. among the s. aureus isolates, the difference in prevalence of resistance to erythromycin between males and females was significant (p = 0.011). the frequency of erma, ermb, ermc, and msra genes ...
