STUDY OF THE EFFECT OF ACETIC ACID ON BIOFILM FORMATION OF PSEUDOMONAS AERUGINOSA ISOLATED FROM DIFFERENT CLINICAL CASES

Abstract

Abstract

In this study, 98 samples were collected from different clinical sources (burns, wounds, urine, blood and sputum) from Baghdad hospitals. After microscopic and biochemical examination, 52 isolates of Pseudomonas aeruginosa were obtained. The ability of bacterial isolates to form biofilm was detected using microtiter plate method, The results showed that 80% of the isolates formed the biofilm in different degrees, 28.9 % Of the isolates, were weak biofilm formation, 24.4 % medium formation and 26.7% strong, A gradual effect of acetic acid (0.009–2.5)% on biofilm formation was also studied, as the acid showed anti-biological activity.
