Vaginal microbial networks in penicillin allergic (AG) and non-allergic (NG) pregnant women at the genus level. The correlation analysis among vaginal bacteria was executed, and the relationships with r value higher than 0.45 or lower than − 0.35 were kept. The red and black edges represented the negative and positive correlation, respectively. The diameter of the spots was proportional to the relative abundance. a Co-abundance network in pregnant women with penicillin allergy. b Co-abundance network in non-allergic pregnant women
