Abstract
A combination therapy of clindamycin phosphate (CLDM) with ceftazidime (CAZ) was used in 2 cases of acute odontogenic infections. In the first case, 2 isolated bacteria strains were Peptostreptococcus micros and β lactamase-producing Prevotella oralis. In the second case, 4 isolated strains were Streptococcus constellatus, P. micros, Porphyromonas gingivalis and, β lactamase-producing Bacteroides capillosus. β lactamase-producing bacteria in two cases were highly sensitive to combination therapy of CLDM with CAZ. In conclusion, combination therapy of CLDM with CAZ is useful for speeding recovery and effective in oral suppurative mixed infections with β lactamase-producing bacteria.
