Bacteriological Study of Chronic Maxillary Sinusitis with Special Reference to Anaerobes

Abstract

Abstract Aspirates from 50 chronically inflamed maxillary sinuses were processed for aerobic and anaerobic bacteria. Bacterial growth was present in 48 (96%) specimens. There were 110 bacterial isolates (2.2/specimen). Forty of the isolates were aerobic or facultative organisms (0.8/ specimen). The predominant aerobic or facultative organisms were Staphylococcus aureus, coagulase-negative staphylococcus (CNS), S. pneumoniae, E. coli, H. influenzae and P. aeruginosa. Seventy anaerobes were isolated (1.4/specimen), Prevotella spp, Peptostreptococcus spp., Porphyromonas spp. and bacteroides spp. being predominant. These findings illustrate the presence of polymicrobial aerobic-anaerobic flora in patients with chronic maxillary sinusitis.
