AN ANALYSIS OF BACTERIAL INFECTION IN CHRONIC SUPPURATIVE OTITIS MEDIA

ObjectiveTo investigate the distribution of pathogen flora in chronic suppurative otitis media(CSOM) and provide the evidence for the treatment.MethodsUsing anaerobic culture incubator,and anaerobic environment was created by using palladiu catalysis.Sixty-five samples with CSOM were collected and cultured for anaerobic and aerobic bacteria separately.(ResultsPathogens) were found in 62 of 65 samples(95.4%),in which,35.4% showed aerobic positive,20.0% anaerobic positive,and 40.0% both positive.The detection rate of anaerobic and aerobic was 60.0% and 75.4%,respectively.The total 109 strains were isolated,including 45.0% anaerobes and 55.0% aerobes,with an average of 1.76 stains in one sample.Conclusion(Aerobic bacteria) were commonly seen pathogens in chronic suppurative otitis media,while anaerobes had a relatively high detection rate,and mixed infection was frequently encountered as well,which suggest of anaerobic bacteria play an important role in this(disease.)
