BACKGROUND: Chronic rhinosinusitis (CRS) significantly lowers the quality of life of patients. The common use of broad spectrum antibiotics for its treatment may alter the pathogens that promote the persistence of this condition. However, the data concerning the distribution of bacteria species. in patients with CRS are not consistent. OBJECTIVE: To isolate the common aerobic and anaerobic bacteria from the middle meatal aspirates of adult patients with CRS and determine their antibiotic sensitivity patterns Methods: This was a case-control study of adults with diagnosis of CRS. Middle meatal aspirate and swab were obtained from cases and control respectively for bacteriological studies. Data analysis was done using Statistical package for social sciences (SPSS) version 17 Result: Forty one aerobic bacteria were cultured. Sixty one percent of the aerobic bacteria isolated were gram positive (staphlylococcus.aureus was the most frequently found) organisms while the remaining 39% was gram negative. Fifteen peicent of the cultured isolates yielded mixed growth of both aerobes (Gram positive and gram negative).3(6%) isolates of Bacteroides species were cultured Conclusion: The present study found that Staphylococcus aureus, streptococcus pneumoniae, Proteus mirabilis, Klebsiella spp, Escherichia coli and Bacteroides spp) were the common bacterial flora in the paranasal sinuses of patients with CRS.
