Abstract
Chronic suppurative otitis media (CSOM) is the most common cause of hearing impairment in the developing countries and it is associated with increased incidence of intracranial and extra cranial complications. To isolate, identify and characterize the Bacterial organisms and detect the antibacterial susceptibility pattern of the isolates by using microbiological methods from specimens of clinically proved cases of chronic suppurative otitis media. A total of 245 patients with CSOM were studied. Swabs were collected from each patient and cultured for bacteria and fungus. Standard methods for isolation and identification of bacteria and fungus were followed. Antibiotic susceptibility testing was done by Kirby-Bauer’s disc diffusion method. Out of the 245 samples studied for bacterial and fungal isolates, 225 samples showed growth of pathogens, 20 samples did not show any growth, 201 samples showed bacterial growth, The most predominant organism was Staphylococcus aureus, 24 samples showed fungal growth, Aspergillus sps being the predominant isolate. Antibiotic sensitivity of organism altered over time, with needs for periodic bacteriological examination. Staphylococcus aureus being most common organism isolated is highly sensitive to cloxacillin and cephelexin. Patients would be benefited by accurate diagnosis of type of infection and the appropriate drug that will be sensitive for the infection can be administered to them.
Keywords: Chronic Suppurative otitis media, bacterial and fungal isolates, Staphylococcus aureus, Aspergillus species.
