Background: Chronic rhinosinusitis is an inflammatory-infectious disease involved paranasal sinuses as a common site of microbial pathogens and infections in patients suffering from the disease. The disease is labeled chronic when it lasts for more than 12 weeks. Objectives: As these infections constitute an important cause of morbidity it can be a strong life-threatening factor, in this investigation we examine the bacterial strains involved in development of chronic rhinosinusitis. Materials and Methods: This research was a prospective study of the bacterial strains involved in development of chronic rhinosinusitis in patients referred to Bou-Ali Sina Hospital in Sari, Iran. The study population included 253 patients with chronic rhinosinusitis. Samples were collected from all patients' nasal discharge, which were cultured to investigate the type of microbial infection. The staining methods were Gram staining, Chinese ink staining, acid-fast staining and Papanicolaou staining. Finally, specific tests for detection and differentiation of the strains were performed. Results: Out of 253 patients, 124 (49.1%) were adult male, 49 (19/36%) were adult female and 80 patients (31.62%) were children under 5 years. The most common clinical symptoms including post-nasal drip (40.47%) and headache (32.62%). In general, the most isolated bacteria were Staphylococcus aureus (37.1%) and Pneumococcus (23.53%). Conclusions: In this study, it was found that S. aureus and Pneumococcus contributed the most to development of chronic rhinosinusitis.
