RNA-seq analysis of Helicobacter cinaedi ATCC BAA-847 under microaerobic and aerobic culture conditions

Helicobacter cinaedi is an emerging bacterial pathogen of immunosuppressed individuals. The species is traditionally thought to require an H2-enhanced microaerobic atmosphere for growth, although it can proliferate under aerobic conditions when co-cultured with epithelial monolayers or supplemented with certain metabolites (notably, L-lactate). The goal of this experiment was to assess the global transcription changes that occur in the H. cinaedi type strain (ATCC BAA-847) under various media and atmospheric conditions. These include bacterial monoculture, as well as co-culture with Caco-2 intestinal epithelial cells. In total, Illumina mRNA-seq (stranded, paired-end) was performed on H. cinaedi grown under 9 in vitro culture conditions (4-5 biologic replicates per condition).
