Effect of sub inhibitory concentrations of antibiotics on adherance of Pseudomonas aeruginosa

الملخص AR

Susceptibility of various isolates of P.

aeruginosa to various antibiotics was tested.

Ciprofloxacin was found to be the most effective antibiotic.

Minimum inhibitory concentrations for ciprofloxacin, Gentamicin, piperacillin and cefotaxime, were specified and ciprofloxacin was found having the lowest MIC as compared with others .

The effect of sub MIC ( ¾ , ½ , ⅓ and ¼ ) of these four antibiotics on adhesion capability of the isolates was tested.

Cefotaxime was uneffective as comparied to gentamycin, ciprofloxacin and piperacillin.

¾ MIC of ciprofloxacin was found the most effective concentration for attenuation of adherence capability.
