Bacteriology of [CSOM] tubotympanic disease and antimicrobials

ABSTRACT

Chronic suppurative otitis media is the inflammation of middle ear by pus producing organisms characterized by discharge and conductive deafness, and is still prevalent around the world. To study the prevalent bacterial pathogens and antimicrobial sensitivity pattern of these isolates. Study of CSOM [tubotympanic diseased] patients at out patient ENT clinic and Microbiology department Sh. Zayed Hospital Lahore. Selection of 100 tubotympanic disease cases from CSOM patients for Bacterial culture and sensitivity. Among Gram positive Staphylococcus aureus represented 34.3% while among gram negative Pseudomonas aeruginosa represented 24.4% and Proteus species were 11.7% of the total isolates. Antimicrobial susceptibility to ciprofloxacin was observed in 92.9% of total isolates followed by sparfloxacin in 92.4%. Septran was the least effective antimicrobial with a sensitivity of only 20.1%. Staphylococcus aureus, Pseudomonas aeruginosa and Proteus species continue to be the major infecting pathogens
