Abstract：Objective To analyze the influence factors of B group streptococcal infection in reproductive tract of perinatal pregnant women and its impact on pregnancy outcome.Methods The perinatal pregnant women who were examined in Jin Coal GroupChengzhuang Mine Hospital from January, 2015 to March, 2018 were studied. All pregnant women were examined by rapid immuno-chromatography (ICA), and 35 normal perinatal pregnant women were selected as the control group, and 41 of them were selected asthe study of B streptococcus infection. The influence factors of B group streptococcal infection in reproductive tract of perinatal preg-nant women and the results of pregnancy outcome were analyzed.Results The incidence of the study group was higher than that of thecontrol group at the age of 35 years above, having a history of abortion, having a history of abortion, having a vaginitis, having nopre pregnancy examination, without using antibiotics, and having no related examination after the birth of a newborn (P＜0.05);the main influencing factors of B streptococcus infection in perinatal pregnant women were old age, vaginitis, history of abortion, noprenatal examination, no antibiotics, and no related examination after birth;the incidence of undesirable pregnancy outcome in thestudy group was 26.83％, and the incidence of bad outcome was 31.71％ in the newborns. The incidence of undesirable pregnancy inthe control group was 8.57％, and the incidence of neonatal adverse outcome was 11.43％. The study group was significantly higherthan the control group.
