Abstract

Routine antibiotics susceptibility testing still relies on standardized cultivation-based analyses, including
measurement of inhibition zones in conventional agar diffusion tests.The sensitivity of the bacterial isolates
causing Clinical isolatest results showed that all the isolates subjected to this study showed varying resistance
to the antibiotics used. The effect of nanoparticles combined with different antibiotics was investigated
against multi resistant Clinical isolates bacteria using disk diffusion method. The inhibition zones diameter
(mm) around various antibiotic discs (Trimethoprim, sulphamethaxazol, Azithromycin, Aztreonam,
Ceftriaxone, Gentamycin, Tetracyclin, Nitrofurantoin) with/without nanopatrticles against isolates were
measured. The antibacterial activities of some antibiotics have been increased in the presence of nanoparticle
against all isolates while others showed no effect. The highest antibacterial activities of antibiotics combined
with nanoparticle were observed against E.coli isolates for Gentamycin, Trimethoprim-sulphamethaxazol
,Azithromycin ,Tetracyclin ,Nitrofurantoin. while A. baumanii appeared sensitive to Gentamycin,
Trimethoprim sulphamethaxazol and Azithromycin compared with antibiotics alone. K.pneumoniae became
sensitive to Gentamycin, Tetracyclin and P.aeruginosa to Ampicillin,Trimethoprim sulphamethaxazol,
Azithromycin and Gentamycin. nanoparticle showed no effect on antibacterial activities of all antibiotics
except Gentamycin against gram positive bacteria S.aureus.
