[Anaerobic bacteria in chronic otitis media].

The work shows microbiological findings of the chronic pus inflammations of the middle ear, emphasising anaerobic bacteria. Samples 170 were examined. 38 patients were under 15 years-of age, and others were between 15 and 60 years-old. Aerobic bacteria were identified by using Cowan's and Steel's conventional methods and Manual's and Sutter's methods were used for identification of anaerobic bacteria. Anaerobic bacteria were found in 23.5% of the samples by improving their cultivation. Findings of cholesteatoma and polyp are the factors that damage aeration so the a good conditions for multiplication of the anaerobes. It is necessary to pay attention to anaerobic bacteria while treating the patients with chronic pus inflammation of the middle ear.
