Michael Pulia of University of Wisconsin/Madison spoke on CA-MRSA
is now the most common pathogen cultured from patients with skin and skin structure infections in emergency departments.
In a previous study in Pennsylvania using electronic health records from 2005 through 2010 from a large health care system, we reported associations between CA-MRSA
infection and residential proximity to high-density livestock operations and the crop fields to which manure was applied (Casey et al.
The epidemiology of CA-MRSA
in Europe differs markedly from that in the United States; >50% of community-acquired S.
is not only of interest to health department sanitarians and hospital infection control personnel, but to housekeeping and environmental services personnel as well.
The Centers for Disease Control and Prevention propose that the CA-MRSA
definition be applied when the MRSA infection occurs in an outpatient setting, or within 48 hours after hospital admission, in an individual who lacks MRSA colonization or infection, hospitalization or residence in a long-term health care facility, surgery, or dialysis in his or her medical history (Nastaly et al.
In summary, we theorize that this patient developed CA-MRSA
bacteremia after incision and drainage of a superficial skin abscess, which resulted in seeding of multiple organs including the heart.
HIV-infected patients are at markedly increased risk for CA-MRSA
7) Distinguishing between CA-MRSA
and HA-MRSA is not always straightforward, since colonization might have been present over a period of time, thus obscuring the source.
Low rates of CA-MRSA
carriage have led to widespread outbreaks of CA-MRSA
disease in atheletic (11) and paediatric populations (12).
10) Over 86% of the isolates were methicillin-resistant, and these MRSA isolates were susceptible to trimethoprim-sulfamethoxazole and clindamycin, consistent with data from CA-MRSA
The investigators compared 586 patients with CA-MRSA
skin and soft tissue infections and 65 patients with invasive disease.
