Microbiological results and MRSA susceptibilities in patients with skin and skin structure infections.

<p>MRSA denotes methicillin-resistant <i>Staphylococcus aureus</i>; MSSA, methicillin-susceptible <i>Staphylococcus aureus</i>; TMP-SMX, trimethoprim-sulphametoxazole.</p>*<p>From the total of patients with positive cultures; 275 pathogens were isolated from 271 patients; 4 patients had two pathogens isolated, respectively; other pathogens include <i>Proteus mirabilis</i> (n = 2), <i>Citrobacter spp</i> (n = 2), <i>Acinetobacter spp</i> (n = 1), E.coli (n = 1), <i>E. faecalis</i> (n = 1).</p>†<p>A single patient may have more than one type of culture.</p>‡<p>From the total of isolates tested; susceptibilities were determined at each microbiology laboratory following their standards.</p

Molecular characteristics of community-associated MRSA in patients with skin and skin structure infections: pulse fieldtypes, sequence types, <i>mec</i> and <i>spa</i> types.

<p>Numbers within parenthesis indicate the number of isolates belonging to each <i>spa</i> type or SCC<i>mec</i> type.</p><p>ST denotes sequence type; ND, not determined; NT, non-typeable.</p>*<p>A representative proportion of isolates from each pulse field type were studied.</p

Clinical and demographic characteristics in patients with skin and skin structure infections due to community-associated MRSA.
