About the study: The role of bacterial communities throughout the body in health and disease is being widely studied. Preliminary research shows a possible link between delivery type (vaginal or caesarean delivery) and the bacterial communities found in the gut in early infancy. In Canada 1 in 4 women have a caesarean delivery and there is some evidence of increased risk of conditions such as asthma, celiac disease, and allergies in caesarean-born infants. To date no cause for this increased risk has been identified. Some researchers have proposed that this potential transfer of maternal vaginal bacteria may be prevented by a caesarean delivery. This may result in altering the establishment of the infant’s own bacterial community. However, a clear link between delivery type and the infant’s bacterial community has not been established. This study will use advanced gene-based methods to profile the bacterial communities present in women who deliver vaginally or via caesarean section and connect these to the infant gut bacterial community in the first 3 months of life. This research will lead to a deeper understanding of the potential role of the maternal bacterial community on the infant gut bacterial community.

Project Title: Vaginal Microbiome Group Initiative Principal

About the study: The VOGUE study team is comprised of a diverse group of scientists and clinicians from across Canada who are using genomic methods to study the microbial ecosystem (microbiome) of the vagina in varying states of health and disease. The VOGUE research program comprises 5 sub-studies, each examining the vaginal microbiome of distinct clinical populations: healthy non-pregnant women, women living with HIV, women with recurrent vulvovaginitis, pregnant women at low risk for preterm birth, and pregnant women at high risk for preterm birth. The team is united in their goal of capitalizing on advances in genomic sequencing technology to analyze the composition, distribution, and function of vaginal microbes, and probe the links between these microbes and diseases to guide the development of novel diagnostic tools and interventions to improve women’s health in Canada and around the world.

Study status: Recruitment for all sub-studies is complete. Data analysis, manuscript development, and knowledge translation are ongoing.

Co-Investigators: Dr. Alan Bocking (University of Toronto), Dr. Sean Hemmingsen (National Research Council’s Plant Biotechnology Institute, Saskatchewan), Dr. Janet Hill (University of Saskatchewan), Dr. Gregor Reid (University of Western Ontario), Dr. Tim Dumonceaux (Agriculture and Agri-Food Canada, Saskatoon), Dr. Gregory Gloor (University of Western Ontario), Dr. Matthew Links (Agriculture and Agri-Food Canada, Saskatoon), Dr. Kieran O’Doherty (University of Guelph), Dr. Patrick Tang (Sidra Medical and Research Center), Dr. Julie van Schalkwyk (University of British Columbia), Dr. Mark Yudin (University of Toronto).
