In Situ Aqueous Spice Extract-Based Antifungal Lock Strategy for Salvage of Foley's Catheter Biofouled with <i>Candida albicans</i> Biofilm Gel.

ABSTRACT: Candida forms a gel-like biofilm in the Foley's catheter (FC) causing tenacious biofouling and severe urinary tract infections (UTIs). For the first time, a spice extract-based antifungal lock therapy (ALT) has been developed to inhibit the Candida albicans gel matrix in FC. Aqueous extracts of garlic, clove, and Indian gooseberry were used as ALT lock solutions and tested against biofilm-forming multidrug-resistant clinical isolates of C. albicans. Reduction in the gel matrices formation in the catheter was confirmed by Point inoculation, MTT assay, CFU, and SEM analysis at 12 and 24 h of incubation. Garlic was effective in controlling both C. albicans M207 and C. albicans S470; however, clove and gooseberry effectively controlled the latter. As evidence
