Colonization of pathogenic bacteria can be the root cause of many urinary tract infections. E.coli and other gram-negative bacteria (Pathogenic Bacteria) adhere to the urogenital tissues in the urinary tract and cause UTI’s. 30% of women will have some sort of urinary tract infection this year. Half the women in the world will have a urinary tract infection (UTI) by the age of thirty. Men are by no means immune.
