BioTech With MicroBio

Multidrug-resistant (MDR) Pseudomonas aeruginosa is a bacterium that can cause severe illness in immunocompromised people. As its name suggests, this microbe is resistant to several antibiotics, making it difficult to treat. How then, are we supposed to fight back? Researchers at Yale University, USA, believe they have found an answer in a pond. A bacteriophage – a type of virus that infect bacteria – that attacks MDR P. aeruginosa was discovered in Dodge Pond in Connecticut. The phage latches onto the bacteria’s cell membrane, preventing the latter from producing enzymes that prevent antibiotics from working, which then makes MDR P. aeruginosa more susceptible to drugs again.
