Which term is used to describe an agent that inhibits bacterial growth but does not kill bacteria?
Bactericidal
Bacteriostatic
Bacteriolytic
Bacteriophage.
The Correct Answer is B
A bacteriostatic agent is an agent that inhibits the growth or reproduction of bacteria, but does not kill them.
This means that the bacteria are still alive, but they cannot multiply or cause infection.
Choice A) Bactericidal is wrong because a bactericidal agent is an agent with the capability to kill bacteria.
This means that the bacteria are no longer alive or viable.
Choice C) Bacteriolytic is wrong because a bacteriolytic agent is an agent that causes the lysis or rupture of bacterial cells.
This means that the bacteria are destroyed and their contents are released.
Choice D) Bacteriophage is wrong because a bacteriophage is not an agent, but a type of virus that infects and replicates within bacteria.
This means that the bacteriophage uses the bacteria as hosts and may kill them or not depending on the type of infection.
