Scientists at NovoBiotic, a pharmaceutical start-up, have made a significant breakthrough in the fight against antimicrobial resistance with the discovery of a potent antibiotic called clovibactin. Derived from a bacterium strain found in sandy soil from North Carolina, this new antibiotic could potentially revolutionize treatment options for infectious diseases.
The development of clovibactin offers hope in the face of a global antimicrobial resistance crisis, which has become the third leading cause of death worldwide in 2019 and is predicted to contribute to ten million deaths annually by 2050.
Dr. Kim Lewis, a microbiologist from Northeastern University, expressed enthusiasm, stating, “I think this is the end of the road in the evolution towards resistance avoidance by antibiotics.” However, she also cautioned that this discovery marked the first step in a long journey towards its successful development and availability for medical practitioners.
The unique nature of clovibactin lies in its ability to hinder pathogens from developing resistance. As an antibiotic that binds to phosphate molecules, which are integral to the structure of bacterial cell walls, clovibactin prevents bacteria from altering the structure without facing severe consequences.
In previous research, Dr. Lewis and her team encountered challenges as 99 percent of bacteria species do not grow cooperatively in lab conditions. However, through an innovative technique, they succeeded in extending the incubation period of a sandy soil isolate, leading to the emergence of a previously unidentified species called Eleftheria Terrae Carolina. From this species, clovibactin was isolated.
Markus Weingarth, a chemist from Utrecht University, further explained that clovibactin disrupts the bacteria’s innard-encasing envelope by collecting and binding peptidoglycan molecules. The bacteria then mistakenly destroy their own membrane in an attempt to eliminate this hitchhiker. This unique mechanism of action presents a promising means to combat pathogens.
Initial studies involving mice infected with MRSA and cultured human lab cells have shown clovibactin’s efficacy in treating infections, with no observed instances of resistance. However, further research and clinical trials are necessary to ensure the antibiotic’s safety and effectiveness in humans.
While the path to developing clovibactin into an approved drug is expected to take approximately a decade, this recent discovery offers a glimmer of hope in the battle against drug-resistant bacteria. The findings by Dr. Lewis and her team highlight the potential for long-lasting and effective antibiotics.
The research study detailing the discovery of clovibactin was recently published in the scientific journal Cell.
