The cervical microbiota clustered into three distinct community state types (CSTs): <i>Lactobacillus iners</i>-dominated cervical microbiota (CST I (38.7%, 24/62)), unclassified <i>Lactobacillus</i>-dominated cervical microbiota (CST II (4.8%, 3/62)), and diverse cervical microbiota (CST III (56.5%, 35/62)) with an array of heterogeneous bacteria, predominantly the bacterial vaginosis (BV)-associated <i>Gardnerella</i>, <i>Prevotella</i>, <i>Sneathia</i>, and <i>Shuttleworthia</i>.
The identified microbiomes were classified into four community state types (CSTs): CST I (dominated by L. crispatus), CST II (dominated by L. gasseri), CST III (dominated by L. iners), and CST IV-A (characterized by a low abundance of Lactobacillus, but with proportions of various species previously shown to be associated with bacterial vaginosis).
