PFGE dendrogram with molecular characterization of nasal and oral MRSA isolates from HIV-infected patients. PFGE cluster was assigned to isolates having ≥80% similarity from the dendrograms. Isolate number indicates the strain number, in which the last letter N and O represent nasal and oral isolates, respectively. Isolates with an identical strain number irrespective of N or O were from the same patient. CIP, ciprofloxacin; Gen, gentamicin; H, hospitalizations; Het, heterosexual; HIV, human immunodeficiency virus; I, intermediate; IDU, intravenous drug user; MRSA, methicillin-resistant S. aureus; MSM, men who have sex with men; P, in jails or prisons; FFGE, pulsed-field gel electrophoresis; PVL, Panton-Valentine leukocidin; R, resistant; S, susceptible; ST, sequence type determined by multi-locus sequence typing; SXT, trimethoprim/sulfamethoxazole (co-trimoxazole); Trans, transmission route of HIV in indicated patient.
