Out of 70 specimens (ear swabs) collected from patient suffering from CSOM, P. aeruginosa was the dominant bacteria with 28% (21 isolates). P. aeruginosa was the commonest bacterial isolated in adult ages group in larger than 10 years old and the proportion of these isolates were increased with the increasing of age and the highest percentage of isolates were seen in the age groups 51 60 years (50%) and 31 40 years (35%). P. aeruginosa isolated in female (60%) higher them in male (40%). Most of isolates show (100%) multiple resistance to Cefotaxime, Amoxicillin, Naldixic acid, Rifampin and Cephalothin, and highly resistance to Gentamycin, Ceftraxone and Cefotaxime (90.4, 90.4, 95.2) % respectively. While resistance of isolates to Ciprofloxacin and Azithromycin append in (2.3 and 4.7) % respectively. The patterns (Ciprofloxacin, Naldixic acid, Cephalothin, Ceftraxone, Cefotaxime, Cefotaxime, Amoxicillin, Rifampin, Gentamycin) represent the highest degree of multiplicity (42.8%) and the patterns (Naldixic acid, Cephalothin, Ceftraxone, Cefotaxime, Cefotaxime, Amoxicillin, Rifampin) represent the lowest degree of multiplicity (9.5%). The resuts of MIC for chemical disinfactants showed that sekulyse inhibit the bacterial growth at the concentration 2 (76.2 %) and 4 (57.1 %), while minudes stopped the bacterial growth at concentration 1 (38.1 %), 2 (47.6 %) and 4 (71.4 %). Skin sept and detolin inhibit bacterial growth at the concentration of 4 (6.3, 42.9) % and 8 (9.5, 14.3) %, respectively. These results showed that minudes is the best detergent for killing P. aeruginosa since it inhibit growth at the MIC (1).
