How ‘Hot Tub Rash’ Bacteria Kills the Competition

A common bacterium fights offِ competitors byِ injecting themِ with toxic proteins a usingِ needle-like puncturing device, scientists haveِ found.
This mechanism givesِ the bacterium, Pseudomonas aeruginosa, anِ advantage inِ its environment andِ helps itِ inِ its quest toِ infect humans byِ eliminating otherِ bacteria, including onesِ helpful forِ human health, according toِ theِ researchers.
In thisِ case, itِ isِ the machinery toِ deliver toxic proteins thatِ attack theِ rival’s protective barrier, called a cell wall causing theِ cell toِ burst.
