Researchers combine amino acid with colistin to treat resistant infections

Chinese scientists report that adding the amino acid L-arginine restores sensitivity in bacteria resistant to the last-resort antibiotic colistin.

New method reverses drug resistance

Researchers in China found that mixing colistin with L-arginine changes the bacterial cell membrane. This structural change allows the antibiotic to enter the cell and trigger the production of reactive oxygen species. The resulting chemical reaction kills the bacterium effectively.

Animal trials show success

Experiments conducted on mice demonstrated that the combination treated infections caused by colistin-resistant pathogens. These findings suggest a rational strategy to overcome rising rates of resistance in gram-negative bacteria. The approach addresses a critical need as resistant infections rise worldwide.
