KEY:

ψ: Representative MRSA for SCCmec typing determined by Kondo et al. (2007).

¶Nasal samples of health care workers (HCWs) in one of the hospitals in Lagos (designated as Lagos1).

Geographical region (Nigeria): South-West (Ile-Ife, Ibadan, Iwo and Lagos); North-East (Maiduguri); North Central (Jos).

GTI: Genital Tract Infection; ASOM: Acute suppurative otitis media.

Antibiotics - PEN: Penicillin; OXA: Oxacillin; GEN: Gentamicin; CIP: Ciprofloxacin; MOX: Moxifloxacin; ERY: Erythromycin; CLI: Clindamycin; TET: Tetracycline; FUS: Fusidic acid; RIF: Rifampicin; COT: Cotrimoxazole; *: Inducible resistance (clindamycin).

UNT: Untypeable SCCmec types; NT: Non-typeable; ND: Not determined.

Isolates with spa type t007, t074, t729 and t1603 were assigned STs based on the Based Upon Repeat Pattern (BURP) via the Ridom StaphType software.

**: MLST on representative strains.
