الملخص EN

Twenty two of P.

aeruginosa were isolated of patients suffering from burn، wound and urinary tract Infections، was determind Minimal Inhibitory Concentration (MIC) towards Four antibiotics، Amikacin، Gentamycin، Rifampicin and Ciprofloxacin.

The results showed high resistance to Gentamycin and Ciprofloxacin at the MIC values were (64-210)μg\ml (32-70)μg\ml respectively.

Whereas some isolates showed susceptible to Amkacin and since the MIC values were (7-25)μg\ml and (4-20)μg\ml respectively.، Rifampicin The isolates showed ability to produce extracellular slime substance and the amount of slime layer were estimated by spectrophotometer.

The results showed relationship between the slime layer ، quantity and an increasing in the MIC value ,the optical density of the slime layer of resistant isolates was (0.5-1.5) compared with sensitive isolates was (0.3-0.4).
