Answer:
If an antimicrobial drug does not exhibit selective toxicity, then the host cells will be damaged.
Step-by-step explanation:
Selective toxicity means that the antimicrobial drug can target, bind and damage a particular molecule that is unique to a microorganism responsible for an infection .
The microorganism selective toxic drug does not make any damage to the molecular structure of the host cell due to low or no selectivity. The anti-microbial drugs those targets plasma membrane are non-selective in nature. These non-selective antimicrobial drugs can also damage the membrane of the host eukaryotic cell along with the membranes of the prokaryotic microorganism like bacteria.
