About the Project

The genus Sutterella encompasses Gram-negative, microaerophilic to anaerobic, bile-resistant bacteria of the Betaproteobacteria that are associated with the mammalian gastrointestinal tract. With the exception of Sutterella stercoricanis (isolated from the canine gut), all member of the genus Sutterella (faecalis, massiliensis, megalosphaeroides, parvirubra, timonensis, wadsworthensis) have been isolated from human faecal samples. Sutterella wadsworthensis is isolated most frequently, but shotgun metagenomic studies have highlighted additional species within the genus Sutterella remain to be characterized. Given the relative ease with which Sutterella spp. can be recovered from intestinal samples – especially from the small intestine, caecum and ascending colon – it is surprising that little to no work has been undertaken to characterize the genomic and/or phenotypic traits of these bacteria. Consequently, host–microbe interactions involving these microbes are poorly understood. Using an in-house collection of Sutterella isolates recovered from human small and large intestine samples over the past 12 years, this project will characterize the genomic diversity of these bacteria, interrogate publicly available datasets to determine the prevalence of Sutterella in human populations, characterize the biochemical and physical characteristics of this interesting but under-explored group of bacteria, and explore the interactions of Sutterella and their metabolic by-products with intestinal cells.

This project would suit a student keen to work in human microbiome research and wanting to develop a mixture of laboratory and computational skills, with full training provided in microaerophilic and anaerobic microbiology and guided learning to develop R- and Linux-based programming skills. You would be part of the Antimicrobial Resistance, Omics and Microbiota (AROM) research group based on the Clifton Campus of Nottingham Trent University (NTU). In addition to attending weekly AROM meetings where you would have the opportunity to present your work, you would be encouraged to present your work at national and international scientific conferences and to publish your research findings in peer-reviewed journals. You would also receive additional relevant training through events and activities organised through NTU's Doctoral School and the School of Science and Technology.
