Pseudomonas aeruginosa - Touch or taste? which one should it like before infecting us?

Pseudomonas aeruginosa
Pseudomonas aeruginosa is a common bacterium that leads to a variety of diseases in plants, animals, and humans and is relatively impervious to antibiotics. For years, scientists remained perplexed at how a single species of bacteria was able to infect such a wide array of hosts. Typically, bacteria use chemical signals to “taste” their environment; if bacteria detect they are in a good place for their survival, they will infect and thrive. Bacteria also rely on “quorum sensing,” the ability to determine how many of their kind are present before mounting an infection. Researchers at Princeton have discovered for the first time that Pseudomonas aeruginosa relies on touch (not taste) for infection. It doesn’t necessarily matter if they’re “tasting” the right environment or not; it just matters if they are on any environment at all. Once attached to any host surface, the bacteria initiate quorum sensing before rapidly overwhelming nearby organisms, including the host.
