Study on Sensitivity of Pseudomonas aeruginosa Isolated from Cystic Fibrosis to Different Antibiotics

Antibiotic sensitivity test was carried out to (6) isolates of Pseudomonas aeruginosa isolated from patients with cystic fibrosis in Mosul city. The test was carried out to (15) antibiotics by disc method , the isolates were sensitive to Tobramycin and Amikacin (100%) , followed by Gentamicin and Ciprofloxacin (83.3%), while they were resistant to the rest of the antibiotics tested. Two-fold dilutions were prepared from Tobramycin , Amikacin, Gentamicin and Ciprofloxacin to determine the Minimum Inhibitory Concentrations (MICs). Tobramycin and Amikacin had (MICs) values in the range of (20-25) g/ml,while (MICs) values for gentamicin were in the range of (12.5-80) g/ml and for Ciprofloxacin in the range of (12.5-320) g/ml.
