The Synthetic Killer Microbes That Have Been Created to Treat

Question

The synthetic killer microbes that have been created to treat Pseudomonas aeruginosa infections
A) respond to the quorum-sensing molecules produced by P.aeruginosa.
B) encode bacteriophage that lyse the pathogenic bacteria.
C) constitutively produce a compound that is toxic to P.aeruginosa.
D) secrete an antibiotic through membrane transporters.
E) have been engineered to produce a stronger toxin than is naturally produced.

Accepted Answer

The synthetic killer microbes have been designed to respond to the quorum-sensing molecules produced by P. aeruginosa, which are used by the bacteria to coordinate their behavior and virulence. By recognizing and responding to these signals, the synthetic microbes can selectively kill the pathogenic P. aeruginosa without harming other beneficial bacteria.
