Epidemic CA-MRSA clone in Argentina: Colonization at admission and permanence during hospital stay.

Four isolates belonging to PFGE type I1-ST5-IVa, spat 311, one non-epidemiologically linked isolate, NE/1300 and three from the same patient with active community onset skin and soft tissue (SSTI) infection: one from wound (W-INF) and two from nasal colonization (at admission, ADM-C and at discharge, DIS-C) were analyzed by WGS to investigate their phylogeny. We aimed to determine if the MRSA strains isolated from the wound at admission and those recovered from the nares also at admission and at discharge after 8 days of hospitalization belonged to the same subtype. Thus, the diversity within host and over time was analyzed.
