Cystitis presents with (5)
dysuria frequency urgency suprapubic pain WBCs (not casts) in urine
Cystitis is primarily caused by what?
Males?
Elderly?
Ascension of microbes from urethra into bladder
Males: infants with congenital defects and vesicoureteral reflux

Predisposing factors of UTI (6)
Obstruction kidney surgery catheterization** GU malformation diabetes pregnancy
Diagnostic markers of UTI:
leukocyte esterase test +
nitrite test+
leukocyte esterase test + = bacterial UTI
Nitrite test + = gram-NEGATIVE UTI
Leading cause of UTI. Colonies show green metallic sheen on EMB (eosin methylene blue) agar
E. coli
2nd leading cause of UTI in sexually active women
Staphylococcus saprophyticus
3rd leading cause of UTI.
Large mucoid capsule and viscous colonies
Klebsiella pneumonia
Some strains produce a red pigment; often nosocomial and drug resistant (UTI)
Serratia marcescens
Often nosocomial and drug resistant (UTI)
Enterobacter cloacae
Motility causes “swarming” on agar
produces urease
associated with struvite stones
(UTI)
Proteus mirabilis
Blue-green pigment and fruity odor (allegedly)
Usually nosocomial and drug resistant (UTI)
pseudomonas aeruginosa
Signs and symptoms of bacterial vaginosis (3)

Lab findings of bacterial vaginosis (2)
