No abstract - Introduction: Cranberry (Vacinicum macrocarpon) is traditionally used in folk medicine for treatment of urinary tract infections. In a recent study, we established that in addition to the antiadhesion effects, concentrated cranberry juice had a direct antimicrobial effect in vitro. We were also able to confirm a direct antimicrobial activity in vitro against a strain of Klebsiella
pneumoniae, in the urine of subjects after ingestion of a commercial cranberry product. While bacteria are the most common cause of urinary tract infections, frequent or prolonged antimicrobial therapy, use of catheters, severely ill patients, high plasma glucose, and invasive procedures can often lead to candiduria. A review of the literature identified one study (Swartz and Medrek 1968), which reported that cranberry juice (40%) in Sabouraud’s dextrose agar had minimal effect on the growth of Candida albicans compared to 0.087% benzoic acid. In this study, we evaluate the anti-Candida activity of urine specimens after ingestion of cranberry.
