Urinary Tract Infection
the most common bacterial infections during pregnancy
asymptomatic bacteriuria is the most common
symptomatic infection includes
cystitis, it may involve the renal calyces, pelvis,
and parenchyma—pyelonephritis
Organisms that cause urinary infections are those from the
normal perineal flora.
Approximately 90 percent of Escherichia coli strains that
cause nonobstructive pyelonephritis have adhesins such as
P- and S-fimbriae. These are cell-surface protein structures
that enhance bacterial adher- ence and thereby, virulence
(Foxman, 2010; Hooton, 2012). These adhesins promote
binding to vaginal and uroepithelial cells through
expression of the PapG gene that encodes the
