Proposal of a Taxonomic Nomenclature for the Bacillus cereus Group Which Reconciles Genomic Definitions of Bacterial Species with Clinical and Industrial Phenotypes

Abstract: The Bacillus cereus group comprises numerous closely related species, including bioterrorism agent B. anthracis, foodborne pathogen B. cereus, and biopesticide B. thuringiensis. Differentiating organisms capable of causing illness or death from those used in industry is essential for risk assessment and outbreak preparedness. However, current species definitions facilitate species-phenotype incongruences, particularly when horizontally acquired genes are responsible for a phenotype. Using all publicly availabl… Show more

“…The virulence and antibiotic resistance genes were annotated using BTyper version 2.3.3 (default settings) (Carroll et al, 2017) and insecticidal toxin-encoding genes were annotated using BTyper3 version 3.0.2 (Carroll et al, 2020). CRISPR-Cas genes were detected using CRISPRCasFinder (Couvin et al, 2018) (Supplemental Table 3).…”

“…The first set (Supplemental Table 5) comprised up to five strains of B. cereus or B. thuringiensis selected from differentiated clades in BCSL_114 and B. thuringiensis phylogenetic trees from previous population structure analyses (Bazinet, 2017, Gillis et al, 2018. The second set comprised 1) the closest genomes to our strain identified using the phylogeny reconstruction of the first dataset (underlined in Figure 5), 2) 121 strains closely related to those according to phylogeny analysis of B. cereus group strains from Carroll et al (2020), and 3) B. thuringiensis YBT-1518 type strain as outgroup (Supplemental Table 6). To ensure the assembly quality of both datasets, only genomes with an N50 size over 20 kbp were selected.…”

“…483 Furthermore, to find the closest genomes to our strain, we performed a focused 484 analysis using the obtained similar strains to HER1410. These strains belong to 485 the same cluster within the phylogeny analysis of B. cereus group from a recent 486 work on its population structure (Carroll et al, 2020). Thus, we selected the 126 487 strains included in this cluster, with the addition of HER1410, and B. thuringiensis Interestingly, as reported here for HER1410, entomocidus has been suggested 512 to harbor cry genes within the chromosome (Carlson and Kolsto, 1993).…”
