English Abstract
Catheter associated urinary tract infections are one of the most common nosocomial infections.
This study aims to isolate, identify and biofilm forming ability of bacteria attached to urinary catheters particularly catheters that had been in place for prolonged periods in preventing catheter-associated infections caused by hospitalized ICU patients.
Urinary catheters from (Clinical center of University Kebangsaan Malaysia) were used, one from Acute Vascular Rejection patient (Urinary catheter B), and two from Benign Prostate Hyperplasia patient (Urinary Catheter C and D).The urinary catheters and urine evaluated quantitatively and qualitatively used colony-forming unit and bacteriological assessment, respectively for each portions of urinary catheter for identifying infections.
Bacterial population on agar plates showed varying density for all parts of three urinary catheters and urine samples.
Altogether 100 isolates including 96 bacterial isolates and 4 yeast isolates have been successfully obtained from the three urinary catheters.
Pathogens were Proteus 22 isolates followed by E.coli 5 isolates, Enterobacter 4 isolates, Klebsiella 3 isolates, Pseudomonas 1 isolates For UC(B), while in UC(C and D) which represent the catheters to same diseases were Pseudomonas 23 isolates showed the highest isolates followed by E.coli 16 isolate, Proteus 10 isolates, Enterobacter 7 isolates, Klebsiella 4 isolates, Candida 4 isolates, Bacillus 1 isolate.
Results of biofilm forming on microtiter plate and sterile Foley catheter revealed that these isolates possess a high capacity for biofilm formation on the both surfaces at different degrees with delay in the initiation of biofilm formation on silicone coated Foley catheter compared to polystyrene microtiter plate.
It is concluded that Gram-negative bacilli were responsible for UTI infections in our patients and almost all of the isolates have the abilities to form visible growing biofilms on both surfaces.
