Bacteria choose to swarm based on what happened to their great-grandparents

Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms when millions of bacteria come together on a single surface. The discovery—which has potential applications for preventing and combatting bacterial infections and addressing antibiotic-resistant bacteria—relates to a common chemical element bacterial cells can use to form and pass along these memories to their progeny over later generations.

The discovery of these memorious microbes has implications for the treatment and prevention of bacterial infections and may help combat antibiotic resistance.

A very intriguing study has unveiled a new aspect of bacterial behavior, revealing that bacteria possess the ability to create “memories”

A new study has found that iron levels trigger the formation of a kind of ‘memory’ in bacteria that drives their subsequent behavior. Moreover, the memory is passed on to future generations. The discovery has potential application in the prevention of bacterial infections and addressing the issue…

Scientists have made an astonishing discovery that suggests bacteria contain memories to be passed on to future generations. Researchers at the University of Texas and the University of Delaware found that despite having no brain or nervous system, certain bacteria may be able to form memories and r…

When we think of bacteria, we think of simple single-celled organisms that basically exist to consume resources and reproduce. They don’t think, feel, or remember… or do they? Bacteria …

Pozdravljeni v novi epizodi oddaje Frequenza della scienza, v kateri se bomo spoznavali s spominom. Natančneje, govor bo o raziskavah bakterijskega spomina in diagnostiki ter imunoterapiji Alzheimerjeve bolezni. V prvem delu oddaje se bomo posvetili bakterijskemu spominu. Še preden pa na valovih Radia Študent zajadramo na to razmeroma novo področje raziskovanja, spomin bolj splošno predstavimo.

New study finds bacteria can form memories related to iron levels, influencing behaviors like swarming and antibiotic resistance

Study reveals bacteria’s astonishing memory-passing capabilities

Funded by the National Institutes of Health, the study contributes to a deeper understanding of bacterial behavior, offering potential avenues for developing therapeutics against bacterial infections and antibiotic resistance.

Scientists at The University of Texas at Austin have discovered how some cells within a bacterial swarm will sacrifice themselves so that other cells in the swarm have a better chance of surviving onslaught by antibiotics, in a discovery important for efforts to address antibiotic resistance.

“Dead cells are helping the community survive.”

The chemical cries of dying bacteria alert the rest of an invading swarm.

This study shows that dying cells can release a signal that alerts their kin to the presence of antibiotics and makes them more resistant.

Swarming is a type of collective motion in bacteria. But it turns out that moving isn’t the only thing swarming bacteria do together. They also send signals that turn on antibiotic resistance mechanisms that are specific to swarming bacteria. The surprising thing is that the bacteria releasing the signals are dead. Souvik Bhattacharyya, David M. Walker, and Rasika M. Harshey of the University of Texas at Austin have now figured out how dead swarming release a protein called AcrA when they die ( 2020, DOI: ). This protein is part of the AcrAB-TolC efflux pump, one of many TolC pumps that the bacteria use to pump drugs out of their cells. The AcrA from dead cells interacts with TolC on the surface of live and stimulates several defense mechanisms, including breakdown of reactive oxygen species and increased expression of TolC and other efflux pumps . The researchers find that other
