Abstract

Objective:-Studying the effect of acetic acid against different types of bacteria causing chronic otitis media.Methods:-Eighty isolates were obtained from (120) ear swab samples suppurative otitis media. They were inoculated directly onto enrichment and selective media for the isolation of the causative microorganisms (bacteria and fungi).The isolates were identified using different microscopically and cultural characteristics and biochemical tests. Final identification of some gram negative bacteria were performed by using api 20 E system. Results: - Pseudomonas aeruginosa was the most common isolated bacteria 48 isolates (40%), followed by Proteus mirabilis and Staphylococcus aureus. which constituted 17 (14.17%) and 15 (12.5%) of the total isolates respectively. Sensitivity of the isolates to antibiotic leveled high resistance to Ampicillin, Amoxicillin, Piperacillin, cefotaxime, Gentamicin and Tobramycin. To less extent was the resistance to Amikacin, Ofloxacin and Ciprofloxacin. All the isolates of pathogenic bacteria were found to be highly sensitive to 2% and 3% of acetic acid solutions. Conclusion: - The study shows that acetic acid has higher effect as a treatment to these bacteria. Key words: - chronic otitis media, resistance of antibiotic, acetic acid.
