Do Bacteria Communicate and Fight? New Research Reveals Their Hidden Social World

Dr. Eran Bosis and Dr. Dor Salomon, who are Israeli researchers from the ORT Braude College of Engineering and the Faculty of Medicine at Tel Aviv University, studied how bacteria interact with one another and with different bacterial species. They reached a fascinating conclusion, that much like humans, bacteria also “choose” their companions, “fight” their enemies, and possess their own kind of “language” with clear behavioral codes.

Their study, published in the scientific journal Nature Communications, revealed that bacteria that battle their rivals have developed sophisticated “tools” to eliminate them. For example, they use a specialized protein secretion system that functions like a toxic arrow.

These proteins carry toxins known as “effectors,” which, true to their name, are highly effective in attacking and neutralizing competing bacteria.

How do these proteins not harm the bacteria themselves? The answer lies in an incredibly advanced internal system that allows them to protect themselves. With the help of additional proteins, the bacteria build a protective barrier that separates them from their own toxins.

According to the researchers, bacteria are also capable of “communicating” with other bacteria they identify as friendly and non-threatening.

What Is the Purpose of This Research?

As with many studies of this kind, the primary goal was to better understand bacterial behavior in various situations, with the hope of developing new types of antibiotic treatments.

If successful, future antibiotics may be able to target only harmful bacteria, rather than destroying both harmful and beneficial bacteria indiscriminately. This would allow for more precise and effective treatment of specific infections.
