Background: Antibiotic resistance currently challenges infectious disease management, specifically in combating biofilm formation. Biofilm might be developed on urinary catheter, in which stroke patients with urinary tract problem have higher risk of catheter associated urinary tract infection and problems related to antibiotic resistance. Aim: This study describes the microbe types from catheter isolates, measuring the antibiotic susceptibility and biofilm formation, especially in stroke patients at Bethesda Hospital, Yogyakarta. Method: This is a cross-sectional study, describing findings of specimens from stroke patients at Bethesda Hospital, since December 2018 to January 2019. The isolates were identified with standard method, the antibiotic susceptibility were tested with antibiotic disc on MHA medium, and the biofilm formation were assessed using tissue culture plate method. All procedure were done in Microbiology Laboratorium, FK UKDW. Result: Thirty three microbes were isolated from 30 specimens of urinary catheter (63,3% male, 36,3% female). There is 76% isolates incapable of developing biofilm, while 15% is moderate biofilm producer and 9% is strong biofilm producer. The susceptibility test showed 100% resistancy of ampicillin-sulbactam, tetracyclin, ketoconazole, itraconazole, and terbinafine. Around 50% of E. coli and 57% of K. pneumonias isolates is MDR, and 75% of A. baumanii is XDR. Conclusion: Isolated microbes from urinary catheter of stroke patients at Bethesda Hospital is dominated by E. coli, K. pneumoniae, and A. baumanii. Some of the microbes could form strong biofilm, and some of the antibiotics could not be used in the future due to their 100% resistancy on all specimens.

Objective: The main aim of this study is to prevent biofilm formation by impregnating an antimicrobial on urinary catheter.Methods: Catheter segments were immersed in the antimicrobial compound for impregnation. After 2 h, the segments were removed, sterilized and dried after which mechanical and antimicrobial properties of the catheter segments were determined. The shelf life of the impregnated segments was also ascertained as well as anti-biofilm assay. Spectral analysis (UV & FTIR) was also performed.Results: Impregnation was achieved by immersing catheter segments in antimicrobial compound ensuring it does not affect the catheter texture. The impregnated antimicrobial catheters were able to prevent colonization by common uropathogens Escherichia coli, Proteus, Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella, and Candida albicans for up to 12 weeks. Antibiotic impregnation of the catheters did not affect the mechanical properties and did not render it as unfit for insertion. The antimicrobial-impregnated catheter offers a means of reducing biofilm formation and subsequently reducing the infection in long-term urinary catheter users. Spectral analysis was done by UV-Vis and FTIR.Conclusion: Antibiotic impregnation of the catheters did not affect the mechanical properties and did not render it as unfit for insertion. The antimicrobial impregnated catheter offers a means of reducing biofilm formation and subsequently reducing the infection in long-term urinary catheter users.
