Normal Microbiota of the Urinary and Reproductive Systems • Urinary bladder and upper urinary tract are sterile • Predominant microbes of the vagina: – Lactobacilli • Produce H2O2 and lactic acid • Growth promoted by estrogen by enhancing the epithelial cells to produce glycogen • Glycogen is broken down to glucose which is metabolized to lactic acid (pH 3 8 acid (pH 3.8-4 5) . – Streptococci, anaerobes, some gram-negatives – Candida albicans yeast: asymptomatic in 10-25% of women • Male urethra is usually sterile Bacterial Diseases of the Urinary System Learning Objectives Describe the modes of transmission for urinary and reproductive system infections. List the microorganisms that cause cystitis and pyelonephritis, and name the predisposing factors for these diseases
