HA-MRSA isolates carried the SCCmec types I (37%; 7/19), IVa (37%; 7/19) and V (26%; 5/19) while CA-MRSA
isolates carried SCCmec types IVa (73%; 8/11) and V (27%; 3/11).
We used South Korea CA-MRSA
strain HL1 (ST72) and its mutant HLl[DELTA]agr in the skin infection model and the hemolysis study for comparison (JO).
The Infectious Diseases Society of America recommends vancomycin and linezolid as first-line drugs for the treatment of CA-MRSA
infection. In our case, vancomycin (1.0 g Q12 h) was initially used to treat the patient (weight, 60 kg) for 12 days.
Skin-to-skin contact among players with traumatic lesions or abscesses has tentatively emerged as the primary mechanism of CA-MRSA
transmission between athletes, although equipment sharing and poor hygiene have also been implicated in the spread of contagions (Cohen, 2005; Turbeville et al., 2006).
The emergence of CA-MRSA
makes the antibiotic choice more challenging.
The first report of CA-MRSA
was indicated from Australia in 1990, and consequently more reports from countries like: France, Finland, New Zealand, and England.
Results: In our study, 5.0% of the patients were found to be infected with HA-MRSA, 72.8%, with CA-MRSA
, and 22.2%, with HACO-MRSA.
Number of CA-MRSA
and HA-MRSA were separated from MRSA isolates from blood cultures and were reported as frequency and percentage.
MRSA is often sub-categorized as HA-MRSA or CA-MRSA
. MRSA is developed by multiple insertions of SCCmec into successful methicillin-susceptible S.
All the MRSA isolates were categorized into Hospital acquired MRSA (HA-MRSA) and Community acquired MRSA (CA-MRSA
) according to CDC definition.
and HA-MRSA have different in vitro sensitivities to antimicrobials, different virulence factors, and different epidemiologic profiles.
A resistencia a [beta]-lactamicos no MRSA e mediada pelo tipo PBP2a (ou PBP2') e no CA-MRSA
adicionalmente pelo PBP4.
