<p>Horizontal numbers on the top of the figure represent de year and month of sampling. Vertical numbers correspond to the 47 vehicles identification.</p

Molecular characterization of 72 MRSA isolates from public buses and 21 MRSA isolates from human carriage (hands and nasal).

<p>HA – Healthcare associated; CA – Community-associated.</p><p>ST – Sequence type.</p><p>nt – non-typeable.</p

Characterization of representative MRSA isolates and comparison with MRSA pandemic clones.

<p>From left to right: (i) dendrogram, showing the estimated relationships of PFGE types based on Bionumerics analysis, including representatives of two international pandemic MRSA clones (EMRSA-15 and Pediatric clone); (ii) list of isolates; (iii) isolation date; (iv) PFGE type; (v) <i>spa</i> type; (vi) MLST sequence type (ST); (vii) SCC<i>mec</i> type; (viii) antibiotype (ATB); and (ix) antibiogram. R - resistance, I - intermediate susceptibility, S - susceptibility; Antibiotic abbreviations: OX – oxacillin, AMP – ampicillin, FOX – cefoxitin, AMC - amoxicillin-clavulanic acid, CIP – ciprofloxacin, E – erythromycin, AZM – azithromycin, IPM – imipenem, K – kanamycin, TOB – tobramicin, CN – gentamicin.</p
