Cranberry versus UTI
It has long been claimed that cranberries help prevent, or even cure, urinary tract infections (UTIs). Cranberry supplementation is available in the form of fresh fruit, dried fruit, juice, and tablets.
Could the cranberry have a role in preventing a UTI? While results have been promising in animal studies, those in humans have been less conclusive. We do know that cranberry products can prevent the adhesion of uropathogens to the epithelium of the genitourinary tract, at least in the laboratory. However the variation in composition and dosage of cranberry products has posed challenges in extrapolating a lot of the data to humans. In some populations, using certain forms of cranberry, the data for reduction in occurrence of UTIs appear promising. For young and middle-aged women, cranberry may be effective in preventing recurrent UTIs. Data do not support effectiveness in older women, particularly those in nursing homes.
There is no evidence that cranberry products treat an active UTI. Antibiotic therapy is the recommended form of treatment. Additionally, cranberry interacts with many medications so their use should be discussed with a pharmacist or provider.
Q. Finding an effective preventive agent could be seen as a particularly pressing need for this particular infection. Why is that?

Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward
