Washington D.C., Nov. 12 -- : A new study used genetic analysis to reveal how two different strains of a single species of flesh-eating bacteria worked in concert to become more dangerous than either one strain alone.

The work suggests that other difficult-to-treat infections may be polymicrobial and treating only one organism in a polymicrobial infection could be the cause of many secondary infections and chronic infections that resist treatment. The results of the study were published in the Journal Proceedings of the National Academy of Sciences, 2019.

In recent years, scientists have found that serious infections that progress rapidly and resist treatment are often caused by multiple microbes interacting with one another. Very little ...
