The isolation, characterization and antibiotic susceptibility studies of Streptococcus pneumoniae strains in malignant ulcers were carried out. The total number of samples that was collected from patients from March toAugust 2007 amounts to One hundred and twenty (120). Eleven (11) different strains of S. pneumoniae were isolated, identified using conventional methods, the antibiotic susceptibility pattern of the isolates and their percentage susceptibility to the different antibiotics was also determined. The Breast and the skin has the highest number of isolates of 5 (45.5%) each. The isolates were 100% susceptible to ciprofloxacin, but were resistant to ampiclox and amoxicillin. The pattern of susceptibility to the antibiotics common to the isolates is ciprofloxacin, streptomycin, pefloxacin and gentamicin. Ciprofloxacin, gentamicin, pefloxacin and streptomycin could serve as potent antimicrobial agent against S. pneumoniae in the study area as revealed by this investigation.
