Antibiotics for culture-positive asymptomatic bacteriuria in pregnant women can prevent pyelonephritis.

Abstract

Asymptomatic bacteriuria, occurring in 2-15% of pregnancies, is generally defined as at least one urine culture showing >100,000 colony-forming units (CFUs)/mL in the absence of fever or symptoms of urinary tract infection.1 Escherichia coli is the most commonly associated pathogen, comprising up to 80% of isolates.
