Mark O Martin is TWiM-adjacent for this discussion of a Fusobacterium nucleatum clade that dominates colorectal cancer, and surface colonization by Flavobacterium johnsoniae promotes its survival in a model microbial community.

TWiM reveals a study showing that positive interactions among bacteria are far more common than previously thought, and how acquisition of a single gene enabled Yersinia pestis to expand the range of mammalian hosts that sustain flea-borne plague.

TWiM continues its food arc with an examination of the effect of peroxyacetic acid spray on the microbiome and sensory properties of beef, and explores asymmetry of the cell division machinery during sporulation.
