In pregnant women, the rectovaginal colonization by Streptococcus agalactiae (GBS) is related with geographic area of origin (6.5% to 36%). It was analysed GBS carriage in pregnant women in 2012-2014 in our hospital. Observational retrospective study about GBS isolates from rectovaginal samples (RVS) and urine cultures of Spanish and immigrant pregnant women in 2012-2014. It was considered only a single isolation for patient. There were excluded women with GBS in urine samples of RVS study. A total of 4,648 Spanish and 1,405 immigrant women were analysed. GBS was detected in urine samples in 231 Spanish (5%) and 106 immigrant (7.6%). A total of 5,716 RVS were analysed, GBS was detected in 10.5% of Spanish women and in 18.9% of immigrant women. The overall colonization in immigrant women is higher than in Spanish with the exception of Asian women. Cases of GBS detected in urine samples might serve as a possible explanation for the high rate of GBS carriage.
