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).
