Predatory bacteria could be used as a weapon against the drug-resistant bacteria or ‘superbugs.’ A predatory bacterium can work with the immune system to clear multi-drug resistant Shigella infections in zebrafish.
Researchers from Imperial College London and Nottingam University in the UK successfully used Bdellovibrio – a bacteria virus- as an ‘injected anti-bacterial therapy’ against Shigella. Shigella causes diarrhea and increasing cases of drugresistant shigella are observed.
To study the effect of Bdellovibrio, Zebrafish was infected with shigella and was then given the therapy. There was a significant decrease in the number of Shigella in presence of the bacteriovirus. Such therapies can be developed further to tackle drug-resistant bacteria.
