摘要

Selection of antibiotics for orofacial infection is usually supported by smear examination of pus and empirical judgement initially. The choice of antibiotics may have to be adjusted according to the results of bacteriologic culture and clinical responses afterward. However, no reports have showed the relationship between this two methods (smear examination, bacteriologic culture). PURPOSE: This study was to investigate the correlation between these two diagnostic methods. MATERIALS and METHODS: Sixty-two specimens were taken from 57 hospitalized patients with abscess or cellulitis in maxillofacial area by swabbing. Gram's stain and bacteriological culture were checked. RESULTS: Forty- three of the specimens showed bacteria in smear. Gram-positive cocci (35/43) and gram- negative bacilli (35/43) were commonly identified. While forty-three of the cultures were positive. Viridans streptococcus (33/53) and Nesseria species (15/53) were most commonly isolated. Strict anaerobes were also present in 16(30.6%) of the specimens. Bacteriodes and Prevotella were usually found. The results showed positive correlation in gram-positive cocci (p＜0.05, Kappa 0.253). CONCLUSIONS: The intrinsic differences in the examination methods, the nature of the bacteria, and technical errors were suggested to explain the discrepancies found in other matchings. The results of this study suggested a need to reevaluate the roles of these two bacterological examination methods in selecting abtibiotics in orofacial infections.
