中文摘要
与人类阴道相关的微生物区系与人类宿主之间存在着相互关联的关系
并被认为对女性的生殖健康起着重要作用。阴道微生物群落
构成了抵御入侵的非本土生物感染的第一道防线,这些入侵生物会导致
疾病,如性传播的沙眼衣原体。
尽管它们很重要,但令人惊讶的是,利特菲知道阴道微生物的组成和动态
在健康和疾病方面交流。传统的基于邪教的方法提供了有价值的
人类阴道微生物区系的不完整图景。在这项研究中,我们将大规模-平行相结合

英文摘要
The microbiota associated with the human vagina exists in a mutualisfic relafionship with the human host
and is believed to play an important role in women's reproducfive health. The vaginal microbial communities
constitute the first line of defense against infection by invasive non-indigenous organisms that cause
disease, such as the sexually transmitted Chlamydia trachomatis.
Despite their importance, surprisingly litfie is known about the composition and dynamics of vaginal microbial
communifies in health and disease. Traditional culfivafion-based methods have provided a valuable but
incomplete picture of the human vaginal microbiota. In this study, we will combined massively-parallel
sequencing technology with the culture-independent analysis of the 16S rRNA gene sequence to survey the
vaginal microbiota species composifion and abundance in young adults with C. trachomatis infecfion and C.
frac/70/r7af/s-positive women with pelvic inflammatory disease (PID). In addifion, we will establish the
dynamics of the community a subgroup of women sampled longitudinally over one year or more after
treatment. In each of these women, we will use community transcriptomics to identify the suite of genes
expressed by the vaginal microbial community. This combined data will afford a unique view of the vaginal
microbiota dynamics during and after Chlamydial infecfion (i.e., a detailed picture of the metabolic pathways
triggered in response to the infecfions (direcfiy or indirectly)], and will further our model of Chlamydial
infecfion and re-ihfecfion. Because of limitations in using humans as research subjects, guinea pigs are used
as animal model for Chlamydial infections. Similarlly, we will characterize the vaginal microbiota in healthy
and C. cawae-infected female guinea pigs over time. Understand and characterizing the importance of the
vaginal microbiota will contribute greafiy to the development of new approaches based on rafionale and
scienfifically sound principles to manipulate the vaginal microbiota in parallel to treatments.
The genome of more than 200 C.trachomatis or C. caviae isolated from these biological samples will be
sequenced using 454 pyrosequencing. These sequences will represent an unparalleled resource that will be
shared with the research community. The sequence data will be analyzed in correlafion with the vaginal
microbiota and the phenotypes characterized under the two projects of this consortium.
