CORIA, María del Pilar et al. Urinary tract infections due to Streptococcus agalactiae and Staphylococcus saprophyticus and pregnancy. Acta bioquím. clín. latinoam. [online]. 2018, vol.52, n.4, pp.423-428. ISSN 0325-2957.

Several authors differ in the greater or lesser prevalence of urinary tract infections (UTI) due to Streptococcus agalactiae and Staphylococcus saprophyticus in pregnant women (PW) and non-pregnant women (NPW). A retrospective, comparative, cohort study was carried out with the objective of evaluating the frequency of UTI by S. agalactiae and S. saprophyticus in asymptomatic PW from primary care centers of the Municipality of La Plata (PCC) between 2008 and 2016 and comparing it with symptomatic NPW in a fertile age, not hospitalized women, who attended the "San Roque" Hospital (HSR) between 2014 and 2017. A total of 2,378 urine samples from PW assisted at the PCC were processed. Two hundred and one were positive (8.5%); 10.4% of them (n: 21) corresponded to S. agalactiae and 10.0% to S. saprophyticus (n: 20). Escherichia coli was isolated in 54%. The total of urine cultures in the population of NPW of the HSR was 2,281 and 526 were positive (23.1%): 7 corresponded to S. agalactiae (1.3%), 18 to S.saprophyticus (3.4%) and 78% to E. coli. In conclusion, the frequency of isolation of S. agalactiae and S. saprophyticus was significantly higher in the population of PW belonging to the PCC than in the NPW studied in the HSR.
