Bacillus cereus is an environmental bacterium that is the second most common pathogen found in food-borne outbreaks in France. The use of routine identification techniques by mass spectrometry of this species does not allow it to be precisely discriminated against among 15 other Bacillus species. When isolated from clinical samples, it is often considered as a contaminant. However, we and others have also recently shown the lethal potential of this bacterium in premature infants.
Recently, we collected clinical data and blood culture isolates of B. cereus from 55 premature infants in 16 French cities. The mortality rate was 23%.
In this project we propose to perform a genomic study of these 55 strains after sequencing their entire genomes. We want to obtain high quality genomes by combining sequencing Illumina and Nanopore long reads technology. The objective is to accurately characterize the strains studied at the species level and to analyse their resistance to antibiotics and virulome. We will also compare these genomes with those already available in public databases. The genome analysis will be carried out in collaboration with Raymond Ruimy, researcher and professor of microbiology at the Nice University hospital and Olivier Croce, head of the Bioinformatics department at IRCAN in Nice. In addition, this project will be in collaboration with the Professor Edouard Fournier of the IHU in Marseille.
