Epidemiology and Susceptibilities of Methicillin-ResistantStaphylococcus aureusin Northeastern Ohio

Abstract

A retrospective survey was performed on all staphylococcal infections diagnosed by the Ashtabula County Medical Center (Ashtabula, OH) during 2006 and 2007. Of the 1,612 Staphylococcus aureus isolates evaluated for their antibiotic resistances, 947 were methicillin-resistant S aureus (MRSA). In 2007, MRSA infections reached 589 cases per 100,000 inhabitants, a 77% increase compared with 2006. The increase in MRSA infections was noticeable among youth (6-25 years old), middle-aged people (45-50 years old), and elderly people (86-90 years old). MRSA infections increased among inpatients by 58%, among outpatients by 43%, and among nursing home residents by 183%. More than 66% of MRSA infections were found among healthy people in the community with no apparent risk factors. More than 88.7% of the infections belong to only 9 profiles of antibiotic resistance indiscriminately distributed among inpatients, outpatients, and nursing home residents. This report sheds further light on the rapid spread of MRSA across Northeastern Ohio, stressing the need for better education in preventive measures and infection control at the level of community and health care settings.

Nasal Carriage of Epidemic Methicillin-Resistant Staphylococcus aureus 15 (EMRSA-15) Clone Observed in Three Chicago-Area Long-Term Care Facilities

“…Long-term care facility (LTCF) residents are at high risk for MRSA carriage (3). Rates of MRSA infection may increase faster in nursing home residents than in hospital inpatients (4), possibly due to unique associated risk factors, such as greater social interaction and multiple interactions with health care workers, including repeated hospital admissions (5). Recent evidence suggests that infection control strategies in the LTCF, such as identification of MRSA carriage and prevention of disease, could have a long-term positive impact on regional MRSA control (6).…”

Performance of the BD GeneOhm MRSA Achromopeptidase Assay for Real-Time PCR Detection of Methicillin-Resistant Staphylococcus aureus in Nasal Specimens

“…In fact, by 2005 MRSA had a higher mortality rate than tuberculosis, salmonella infection, influenza, and HIV-AIDS combined within the United States (5). Moreover, Delorme and colleagues recently reported an increase of MRSA infections and disease rate in long-term care facility (LTCF) residents between 2006 and 2007 (6). There has been some success reported in the reduction of invasive infection since 2005, but most of the improvement was related to bloodstream infection and may be related to improved central venous catheter management in acute care hospitals (11).…”

Study of antibiotic resistance profiling of Staphylococcus aureus isolated from clinical specimens of the patients attending a tertiary teaching hospital from Chhattisgarh

“…Isolation varied from males to females in different studies. 4,9,10 Wounds and abscesses were considered to be the mostly caused by S. aureus. Similar observation was reveled in the present study.…”
