Microbiological study of orofacial infections of odontogenic origin in Iraqi patients and their sensitivities to cefotaxime

Abstract

Background: This study was carried out to evaluate microbial flora of odontogenic infection in Iraqi patients and togain further information on the types of micro-organisms in odontogenic infection, and to determine the value ofCefotaxime as an alternative drug in the treatment of odontogenic infection.Materials and methods: The bacteriology of 20 dento-alveolar abscesses was studied using optimal techniques tocollect, transport and processing specimen. All specimens yielded bacterial growth when cultured for aerobes andanaerobes. Anaerobes were isolated in all patients.Results and Conclusions: Among the aerobic bacteria, streptococci dominated and among the anaerobes theGram negative rode, bactericides ruminicola and fusobacterium nucleatum were most frequently isolated followedby Gram positive cocci. All anaerobic isolate were resist to cefotaxime. The results generally showed that Cefotaximemost effective drug against Gram negative rods and less active against Gram positive cocci and this being relatedto the laboratory results of culture and sensitivity
