Antibacterial activity of human urine [PDF]
Journal of Clinical Investigation, 1968 The fate of bacteria in human urine was studied after inoculation of small numbers of Escherichia coli and other bacterial strains commonly implicated in urinary tract infection. Urine from normal individuals was often inhibitory and sometimes bactericidal for growth of these organisms.

Hydroxylysine Glycosides in Human Urine
Clinical Chemistry, 1971 Abstract Hydroxylysyl-galactosyl-glucose (HGG) and hydroxylysyl-galactose (HG) were isolated from normal human urine and shown to be identical with hydroxylysine glycosides (OHLG's) whose structure had been elucidated in other laboratories.
