turicibacter turicibacter turicibacter is a genus in the bacillota phylum of bacteria that has most commonly been found in the guts of animals. the genus is named after the city in which it was first isolated, zurich (latin = turicum), switzerland. turicibacter turicibacter sp. h121 cells under microscope turicibacter sp. h121 colonies scientific classification domain: bacteria phylum: bacillota class: erysipelotrichia order: erysipelotrichales family: turicibacteraceaeverbarg et al. 2020 genus: turicibacterbosshard, zbinden & altwegg 2002 type species turicibacter sanguinisbosshard, zbinden & altwegg 2002 species t. bilis maki & looft 2022 t. sanguinis bosshard, zbinden & altwegg 2002 phylogeny the position of turicibacter within the bacillota could not be resolved using 16s rrna gene-based analyses. however, it was tentatively placed in the class bacilli, then the class erysipelotrichia. in a tree built using a concatenated protein alignment containing data from two draft turicibacter genomes, the group was placed at the base of the class bacilli. later analyses that also included amino acid sequences predicted by a complete turicibacter genome came to the same conclusion.
