مطالعه مقایسه ای انواع باکتریهای بیماریزا ( هوازی ، بی هوازی) و قارچها در بیماران مبتلا به التهاب عفونی گوش میانی و سینوس

Infection of middle ear and infection of sinuses are prevalent diseases in human populations which are caused by various etiological agents. To determine and compare the frequency of different virulent bacteria and fungi, the following study was conducted. 58 Patients with sinusitis and 52 with otitis media, which were candidates for surgery were studied irrespective of age and gender. Tissue samples or samples from local discharges obtained at the operation room were transfered to the laboratory in suitable transport media and were directly studied and subsequently cultured for the presence of aerobic and anaerobic bacteria and fungi. In the sinusitis patients the most prevalent virulent agents were bacteria (65.51%). The most prevalent aerobic bacteria isolated were S. aureus and S. epidermidis (62.92% in total) (P<O.OOO). Also in the patients with otitis media the most prevalent virulent agents were bacteria (71.14%). Considering the results of this comparative study, the frequency of aerobic bacteria was more than that of anaerobic bacteria in the patients of otitis media and the most prevalent aerobic bacteria are Pseudomonas and S. aureus specious (57.13% in toltal) (P<O.OOO).
