OBJECTIVE:

To determine the prevalence of asymptomatic bacteriuria, its adequate treatment based on the antibiogram report of pregnant patients who attended prenatal control in a private clinic.

MATERIALS AND METHODS:

Retrospective study of a case series, descriptive and cross-sectional carried out in pregnant women who attended prenatal control in the outpatient clinic of the Hospital Fray Juan de San Miguel de Uruapan, Michoacán, between January 1, 2019 and December 31, 2021. Study variables: mothers' age, weeks of pregnancy, pregnancies, bacteriuria, causative agent, indicated antibiotic and response to treatment. Descriptive statistics, measures of central tendency and simple frequencies were used to interpret the results obtained.

RESULTS:

A total of 227 pregnant women were studied; 49 of them had a positive urine culture. The prevalence of asymptomatic bacteriuria was 21.59. Escherichia coli was the most reported causative agent. Of the control urine cultures 36 of 37 were negative and only 1 of 37 was positive.

CONCLUSION:

The prevalence of asymptomatic bacteriuria in this study was 21.59% and the main etiologic agent was E. coli in most cases, with sensitivity to nitrofurantoin in most cases.
