Introduction. Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) represents a risk for the spread of bacteria. This study characterized the S. aureus isolated from medical students, who were in their clinical rotation at a hospital in the city of Cali. Materials and Methods. 216 students participated in the study and 63 isolates of S. aureus were evaluated for susceptibility a...

The purpose of this study was to assess the prevalence of Staphylococcus aureus nasal carriage of dairy sheep in farms producing cheeses manufactured with raw ewe's milk. The study showed that 29% of ewes carried S. aureus in their nares. The genetic diversity of the 136 isolates recovered from the anterior nares of the ewes, from the ambient air of the milking parlour and from cheeses was inve...

BACKGROUND A major risk factor for the development of surgical site infections is Staphylococcus aureus carriage. Compared with non-carriers, S. aureus carriers have up to a 14-fold greater risk for post-surgical infections. Pre-operative screening for S. aureus carriage is controversial. Yet, targeted screening in high-risk patients or from clinically relevant sites may be beneficial. We aimed...

background coagulase-negative staphylococci (cons) are opportunistic pathogens. methicillin resistance is common in cons and may play an important role as reservoir of staphylococcal cassette chromosome mec (sccmec) for staphylococcus aureus. objectives the aim of this study was to determine molecular characteristics of nasal carriage of methicillin-resistant coagulase negative staphylococci am...

conclusions the occurrence of multidrug-resistant s. aureus in the elderly cohort indicates their capacity to serve as reservoirs for these strains, which could facilitate the dissemination of mrsa into the community. therefore, decolonization and the implementation of measures to prevent the spread of this organism are necessary. results fifty (21.7%) s. aureus strains were identified among th...

The investigation was conducted between 1956 and 1959 in a small, single-handed general medical practice situated in a pleasant residential area in south Manchester. Thirty-seven families were investigated for periods ranging from 12 to 24 months. Anterior nasal swabs were taken from all members of each household every six weeks-a purely arbitrary interval-while any intercurrent staphylococcal ...
