Different antibiotic regimens for treating pregnant women with bacteria in their urine and without symptoms of urinary tract infection

Between 5% and 10% of pregnant women have bacteria in their urine without symptoms of infection (asymptomatic bacteriuria). If left untreated, women may go on to develop serious complications such as kidney infection or preterm birth.
