BIOLOGY 113 - MICROBIOLOGY Lecture 37: Microbial Diseases of the Urinary and Reproductive Systems __________________________ Genital and urinary tract infections - Physiological defenses of the urinary tract - mechanical flushing action, acidic pH of urine, phagocytes in the urinary tract, immunoglobulins produced by cells in the bladder and kidneys - Normal urinary tract flora present only in the distal urethra, usually related to GI tract flora - Cystitis - bladder infection, quite common = May be asymptomatic, revealed only by presence of bacteriuria = Women more susceptible than men for anatomical reasons = Accurate diagnosis requires quantitive determination of bacterial counts in urine - Kidney infections = Pyelonephritis usually results from ascension of bladder infection, a good reason for prompt treatment of cystitis = Glomerulonephritis usually results from deposition of immune complexes - Gonorrhea, infection by Neisseria gonorrheae , a microaerophile = Neisseria gonorrheae does not invoke an effective immune response
