[Antimicrobial activity and frequency of spontaneous gentamicin-resistant mutants in bacteria related skin infections].

Gentamicin is used in an ointment form for the treatment of skin infections. To investigate the effect of gentamicin used as an ointment, the antimicrobial susceptibilities against Staphylococcus aureus, coagulase-negative staphylococci, Streptococcus pyogenes, and Pseudomonas aeruginosa isolated from community and medical settings were studied and compared with other antibacterial agents such as fradiomycin, chloramphenicol, and bacitracin used as active ingredient for each ointment. Gentamicin showed antibacterial activities for all standard bacteria tested, but fradiomycin and chloramphenicol showed no such activities for St.
