Apparent competition in the human microbiome

Apparent competition has also been viewed in and on the human body. The human immune system can acts as the generalist predator, and a high abundance of a certain bacteria may induce an immune response, damaging all pathogens in the body. Another example of this is of two populations of bacteria that can both support a predatory bacteriophage. In most situations, the one that is most resistant to infection by the shared predator will replace the other.

Apparent competition has also been suggested as an exploitable phenomenon for cancer treatments. Highly specialized viruses that are developed to target malignant cancer cells often go locally extinct prior to eradicating all cancer. However, if a virus were developed that targets both healthy and unhealthy host cells to some degree, the large number of healthy cells would support the predatory virus for long enough to eliminate all malignant cells.
