Hi Phil;

Yes I think you are probably right - see second sentence in this study. --

The effect of water, ascorbic acid, and cranberry derived supplementation on 
human urine and uropathogen adhesion to silicone rubber.

In this study, urine was collected from groups of volunteers following the 
consumption of water, ascorbic acid, or cranberry supplements. Only ascorbic 
acid intake consistently produced acidic urine. Photospectroscopy data 
indicated that increased water consumption produced urine with lower protein 
content. Surface tension measurements of the collected urine showed that 
both water and cranberry supplementation consistently produced urine with 
surface tensions higher than the control or urine collected following 
ascorbic acid intake. These urine samples were also employed to study 
uropathogen adhesion to silicone rubber in a parallel plate flow chamber. 
Urine obtained after ascorbic acid or cranberry supplementation reduced the 
initial deposition rates and numbers of adherent Escherichia coli and 
Enterococcus faecalis, but not Pseudomonas aeruginosa, Staphylococcus 
epidermidis, or Candida albicans. Conversely, urine obtained from subjects 
with increased water intake vastly increased the initial deposition rates 
and numbers of adherent E. coli and E. faecalis (P < 0.05).
