Bacillus toyonensis

◑ Environmental
Sequenced
Public genome assembly available

Bacillus toyonensis is a spore-forming bacterium in the Bacillus cereus group, used in some veterinary feed additive applications (historically marketed as Toyocerin for livestock). The available research for this organism focuses heavily on agricultural and environmental contexts — biocontrol of plant pathogens, enzyme production, and flocculation — with limited work in the context of veterinary immune-related research in puppies. B. toyonensis is phylogenetically close to B. cereus, a recognized foodborne pathogen; the safety profile for human supplementation requires careful consideration. No human clinical trial evidence was identified for this organism, and it is not a recognized human probiotic strain. These are research topics, not findings; the papers do not establish that this strain treats or prevents any condition.
