Taking fish oil might help reduce antibiotic resistance.



Omega 3 Fish Oil Capsules

For the first time, Australian scientists have confirmed a link between the role common fish oil plays in disrupting the ability of ‘superbugs’ to become resistant to antibiotics.

discovery led by Flinders University and recently published in an international journal. mBioIt was found that the antimicrobial activity of fish oil fatty acids could prove a simple and safe supplement for people taking antibiotics to fight infections more effectively.

“It is important that our study indicates that a key antibiotic resistance mechanism in cells may be negatively affected by dietary fat absorption in omega-3s,” said microbiologist Dr. Bart Eijkelkamp, ​​head of the laboratory. Bacterial adaptation research at Flinders University said.

“In experiments and modeling supercomputers, We found that these fatty acids in fish oil make bacteria more susceptible to many common antibiotics.”

The research is significant in infectious diseases caused by bacteria such as Acinetobacter baumannii, a leading hospital pathogen with unprecedented levels of antibiotic resistance worldwide.

Dr. Felice Adams, another co-author, said: “With the rise of superbugs now, we’ve been able to show that greedy bacteria are unable to differentiate between ‘good and bad’ host fatty acids, and will consume all of them during infection,” said the co-authors. Another from Dr. Felise Adams from Flinders University.

“Our research shows that fish oil fatty acids become part of the bacterial membrane and make the invading bacterial membrane more susceptible to the antibiotic used to attack it.”

“We know that Acinetobacter baumannii is one of the world’s most famous multidrug-resistant pathogens. But the host’s response to stress is poorly understood.”

Professor Anton Peleg, Director of the Department of Infectious Diseases at Alfred Hospital. Melbourne said: “These studies provide new insights into the potential benefits of omega-3 supplements for bacterial infections. especially during antibiotic treatment.
