[Microbiology of acute exacerbation chronic sinusitis in adults].

The bacterial flora taken by sinus puncture from 115 patients with uni and bilateral acute exacerbation of chronic maxillary sinusitis was analyzed. Germ-free culture was obtained in 49 cases (40%) and in 69 cases (60%) bacteria were isolated from all sinus aspirates. Microbiological evaluation shows, that in majority of cases (90%) of acute exacerbation of chronic sinusitis there were pathogenic bacteria namely aerobic and anaerobic. The most frequent pathogens isolated from the aspirates were; Staphylococcus aureus, Haemophilus influenzae, Escherichia coli, Streptococcus pneumoniae, Staphylococcus hominis, Propionibacterium acnes i Candida albicans. The culture analysis proves that one or more pathogens can be the etiological factor. In the majority of cases (64%) the sinusitis is caused by monoculture.
