In the current scenario, bacteria have found ways to evolve and overcome the antibiotics that inhibit them. One such new mechanism is communication between them helping them to resist antibiotics.
Researchers from the University of Copenhagen and the University of California Irvine conducted a study on Pseudomonas aeruginosa. The researchers mimicked an environment similar to the respiratory tract where the bacteria usually multiply. By doing so, they saw growth and multiplication of the organism. Such organisms, when counter-attacked with antibiotics, were observed to begin a new method of communication between the organisms.
These organisms usually swim freely around the medium. However, when one of them gets hindered either by an antibiotic or bacteriophage, they seem to send signals to other organisms. Therefore, leading other members to swim around it and not getting hindered or dead. This naturally occurring communication will help them from inhibiting them. This can possibly explain why this bacterium is resistant to most of the antibiotics.
Pseudomonas aeruginosa is on the top of the list of critical organisms on the WHO’s list. The organism is resistant to most of the antibiotics in the world. Therefore, new antibiotics are in the need to treat this infection. Also, one should note that these organisms are responsible for respiratory tract infections that cause wide mortality, due to their resistance. With this fresh, new finding, researchers could possibly find ways to tackle resistant bacterium. This will also give us leads into understanding new mechanisms of resisting antibiotics. Lastly, this may also help us in finding a newer generation of antibiotics.
