When looking at some type of possible bacterial therapy something to keep in mind is
Quorum sensing, what no drug, injection or supplement is capable of.
Bacteria sensing and responding to its environment through communication with other bacteria and the host.
In biology, quorum sensing is the ability to detect and to respond to cell population density by gene regulation. As one example, quorum sensing (QS) enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial.
Quorum sensing allows bacteria populations to communicate and coordinate group behaviour.
This could be both pathogenic and beneficial.
Im looking at this bacterial group right here it includes both Bifido and Propionibacterium.
Early colonizers.
Quorum Sensing: An Under-Explored Phenomenon in the Phylum Actinobacteria
A systematic and coordinated effort is required to screen and exploit the enormous potential that quorum sensing in the phylum Actinobacteria has to offer for human benefit.
