Cell sub-journal: The bacterial war did not surrender a said, but can not launch a suicide attack.

Bacteria are aggressive creatures, and they have evolved a series of harsh strategies to kill and suppress competitors.one of the most extreme of these strategies is that cells actively divide and die to release large amounts of toxins to kill other strains.although we know that some bacteria do, it is not known whether this behavior is universal.recently, in a new study published in current biology, researchers from the Department of animal and biochemistry, Oxford University, UK, found that in a bacterial war, in order to defeat its competitors, the warring bacteria will carry out a large number of suicide attacks.this study shows that in some areas of the bacterial battlefield, almost all bacteria kill themselves, resulting in large-scale simultaneous attacks.Image Source: Current Biology suicides are very rare in nature, and it's hard to understand why they evolved.this study shows that millions of bacteria commit suicide at the same time.in addition, this also exists in all well studied bacteria, such as the common intestinal bacterium E.coli.this finding has striking similarities with the behavior of social insects, bees and ants, which can also launch large-scale suicide attacks on invaders.Image Source: Dr. ELISA granato, lead author of the current biology study and Department of animal and biochemistry, Oxford University, said: "the number of bacteria killed in these attacks is surprising.but our study explains why they do this: when cells are killed by a competitor's toxin anyway, they go for a suicide attack.this is the last attack of cells, a powerful counterattack launched before death."in this study, the researchers used 3D time-lapse fluorescence microscopy to observe the bacterial battlefield in the laboratory.they used a method that allowed cells to change color when they committed suicide.this allows researchers to track specific cells on the front line of the battlefield over time, observing the time and number of attacks they make with competitors.Image Source: Professor Kevin foster of the Department of animal and biochemistry, Oxford University and Research Associate of current biology, said: "bacteria like E.coli can be both lethal pathogens and protective symbionts that live in our bodies.therefore, whether these bacteria can win the war will determine whether you have good health or have destructive diseases. therefore, the study of bacterial warfare may help us both to repel pathogens and to promote so-called "friendly" bacteria. "researchers hope that through a broader understanding of the laws of bacterial warfare, probiotics can be designed to promote our health and treat infections. article link: this official account is hosted by the Microbiological Resource Center of the Institute of Microbiology and the big data center of the Chinese Academy of Sciences.
