경부심부감염에서 동정균 및 항생제 감수성 고찰

Abstract

Background and Objectives：The incidence of deep neck infection has decreased after the introduction of antibiotics and improvement of oral hygiene, but they still may be lethal especially when life-threatening complications occur. The purposes of this study are to find out common organisms, rates of antimicrobial resistance in the deep neck infection. Subjects and Method： We have conducted a retrospective study of 76 patients with the diagnosis of deep neck infection that had been seen between January 1998 and December 2003. Results：The most common pathogens found were Streptococcus viridans (34%), followed by Klebsiella pneumoniae (19.4%), Streptococcus Group F (11.9%), β-hemolytic streptococci (11.9%) and Peptostreptococcus (7.5%). Staphylococcus species was not found. Of the aerobes found, 74.1% were sensitive to all antibiotics. All Streptococci, with one exception, were not resistant to any antibiotics. All Klebsiella pneumoniae were resistant to ampicillin. Klebsiella pneumoniae were cultured in 50% of DM patients. Conclusion：The most common pathogens were Streptococcus viridans (34%). Of these aerobes, 74.1% were sensitive to all antibiotics. All isolated microorganisms were sensitive to ampicillin/sulbactam (Unasyn??) used before the results of bacterial cultures.
