J bacteriol: deadly bacteria avoid antibiotic attack by communicating with each other

November 25, 2019 / BIOON / -- bacterial infection is not only an unpleasant experience, but also a major health problem, especially some bacteria have developed resistance to antibiotics As a result, researchers are trying to develop new antibiotics that can fight bacteria, while trying to make the current antibiotic treatment more effective Now researchers have made a breakthrough in Pseudomonas aeruginosa infection, which is notorious for infecting the lungs and causing cystic fibrosis In a new study, researchers found that when bacteria are attacked by antibiotics or phages, they send warning signals to other "peers." In the study, conducted by the University of Copenhagen and the University of California, Irvine, researchers studied the growth and distribution of bacteria in dishes Here, they create an environment similar to the mucosal surface where infection can occur, like the lungs of patients with cystic fibrosis (image source: www Pixabay Com) in this environment, researchers can see not only the normal behavior of bacteria, but also their behavior when they are affected by antibiotics and phages Through research, we found out how bacteria spread and change their behavior so that the entire bacterial population can survive They are almost a unified organism " Pseudomonas aeruginosa bacteria are such a big problem that they are listed as the most important "critical" category in the WHO bacterial list, where new antibiotics are most needed So researchers are happy to find out how the bacteria behave and survive Nina Molin h ø yland kroghsbo, the author of the paper, believes that substances that may prevent other bacteria from receiving signals can be designed, which may make the treatment of antibiotics or phage viruses more effective Source of information: dangerous bacteria communication to avoid antiotics original source: Julia C van Kessel PQS signaling for more than a quorum: the collective stress response protection health Pseudomonas aeruginosa populations Journal of biology, 2019; 201 (23) doi: 10.1128/jb.00568-19
