Can broccoli be the answer to antibiotic resistant pathogens?

Could a phytochemical derived from vegetables like broccoli be the answer to antibiotic-resistant pathogens?

Israeli researchers say they have found a suitable candidate.

Antibiotic-resistant bacterial pathogens are increasingly playing a role in rising illness and preventing wound healing, especially in hospitals.

While more and more pathogens have developed biofilms that protect them from being eradicated by antibiotics, fewer classes of antibiotics are being developed.

Researchers from Israel decided to go in a different direction and investigated a phytochemical derived from cruciferous vegetables such as broccoli that breaks down the biofilm.

Phytochemicals are chemical compounds made by plants.

The phytochemical 3,3′-diindolylmethane (DIM) successfully broke down the biofilms protecting two different important pathogens including Acinetobacter baumannii and Pseudomonas aeruginosa – enabling their eradication 65% and 70% of the time, respectively. Combined with antibiotics, that number jumped to 94%.

Prof. Ariel Kushmaro, Dr. Karina Golberg and his team together with Prof. Robert Marks, chronicled their findings in the peer-reviewed journal Pharmaceutics recently.

Additionally, when they introduced DIM into an infected wound, it sped up the healing process significantly, the team found.

“Our findings show promise for other avenues of research in addition to known classes of antibiotics,” says Prof. Kushmaro.
