Antibiotic resistance in pathogenic microorganisms is a serious threat to successful therapy. The aim of the present study was to determine antibacterial efficacy of condensed cashew apple (Anacardium occidentale L.) against antibiotic resistant urinary tract pathogens. The juice was extracted from ripe cashew apples and concentrated to 1/10th of original volume. Inhibitory activity of condensed cashew apple juice was tested against five urinary tract pathogens by Agar well diffusion assay. Among Gram negative and Gram positive test bacteria, Pseudomonas aeruginosa and Enterococcus faecalis were inhibited to higher extent respectively. Least inhibitory activity was observed in case of Escherichia coli. Antibacterial efficacy of condensed cashew apple juice could be attributed to the presence of inhibitory components present in it. Further studies on separation of bioactive components and determination of their inhibitory activity against uropathogens are to be carried out.
