Bacterial pattern of chronic rhinosinusitis FESS candidates and their antibiotic susceptibility in northeast of Iran
Sinusitis is a major cause of illness in the world, an represents a substantial economic burden. Accurate diagnosis and appropriate antibiotics will optimize the chances of achieving and early cure. The main factors in choosing antibiotic therapy are likely infecting pathogens, and the pattern of bacterial antibiotic resistance, endoscopically directed middle meatal aspiration culture is increasingly used in this setting; But studies have not convincingly demonstrated the validity of this technique. So this study was undertaken over a 12-month period to identify causing pathogens of chronic sinusitis and their antibiotic susceptibility pattern in northeast of Iran. Over a 12-month period, a total of 32 samples were taken from 16 patients diagnosed as having chromic bacterial rhinosinusitis. The samples were sent to he laboratory where a pathogen was identified and antibiotic susceptibilities were determined. Most bacteria isolated were aerobic or facultative bacteria. Gram-negative rods as entrobacter spp. (18.5%), klebsiella pneumonia (15.4%), E.Coli (9.23%) and staphylococcus aureaus (15.4%). Although appropriate techniques for anaerobes cultivation were employed, anaerobes were identified in just 3 specimens. The predominant anaerobes isolate was fusobacterium. The results of this study can give practicing physicians vital information about pathogen profiles and susceptibilities within our communities and help them in making appropriate treatment choices for their patients with chronic rhinosinusitis.
