Answer 2

Answer:

Chemotherapeutic agents should act against the pathogen and not the host.

Explanation:

Selected toxicity -This is the toxicity  of an agent, which has a negative effect on certain class of cells, while excluding others. In application to antimicrobial drugs, it refers to ability of  a drug to selectively kill or inhibit the  the targeted pathogens, while causing little or no  harm  to the cells of the host. it is also applicable in the use of insecticide and weedkillers where the hosts(human, animals or  farm crops) are not really affected, but the targeted insects and weeds  are destroyed.

It works by  disrupting the  specific chemical bonds and neurotransmitters  in the targeted cells of the microorganisms.
