Susceptibility of Pseudomonas aeruginosa isolated from urine to some antibiotics

Pseudomonas aeruginosa is a member of genus Pseudomonas that it is Gram – negative , glucose nonfermenting aerobic rod , isolated from chronic UTI . It is resistant to high concentration of salts and dyes , weak antiseptics and commonly used antibiotics. Because of the increasing in drug – resistant of strains of P. aeruginosa especially that which isolated from UTI, this study was done among the patients attending hospitals in Al-Najaf city during January to December 2009 to maintain the susceptibility pattern of organism isolated from urine specimens. A total 72(100%) samples of P. aeruginosa were isolated from urine specimens of patients. The bacteria isolated were identified by colony morphology , microscopy and relevant biochemical tests. Antimicrobial sensitivity pattern was tested using standard guidelines. Almost all of the P. aeruginosa isolates were sensitive to Amikacin(100%) , Norfloxacin(86 % ( Ciprofloxacin(83 %) & Tobramycin(83%) but highly resistant to Doxycycline.
