Abstract
Bacteria were isolated from the rhinorrhoea of 1060 patients with sinusitis. A total of 1081 bacteria cultures were established using samples taken from 778 patients. The cultures were identified as S. pneumoniae (40.4%), M. catarrhalis (26.4%), and H. influenzae (25.3%). Many of the S. pneumoniae cultures were resistant to AMPC (Amoxicillin), with only 18.3% showing sensitivity.
M. catarrhalis were frequently isolated in samples taken from babies and infants.
In school aged children and younger, the freguency at which M. catarrhalis was isolated decreased to about 10%. On the other hand, the frequency of MSSA increased in patients older than schoolchildren. About 1.7% of the 1081 bacteria cultures were classified as MRSA. MRSA bacteria were resistant to most antibiotics. Only 33.4% of the isolated bacteria cultures were sensitive to AMPC in vitro, 63.4% of the cultures were sensitive to SBTPC (Sultamicillin), and 46.6% of the cultures were sensitive to CAM (Clarithromycin). LVFX (Levofloxacin) was the most effective antibiotic, with 98.0% of the cultures showing sensitivity. CMX (Cefmenoxime), which is often used in aerosol therapies, was also effective, with 96.7% of the cultures showing sensitivity.
