Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The easiest microbial forms to kill or inhibit are
A
vegetative bacteria and fungi
B
endospores
C
prions
D
protzoan cysts
Explanation: 

Detailed explanation-1: -Answer and Explanation: The easiest microbial forms to kill or inhibit are vegetative bacteria and fungi because they are susceptible to many antimicrobial agents and disinfectants. Naked virus lacks the outer envelope that contains lipid and therefore, is less susceptible to disinfectants.

Detailed explanation-2: -Gram-positive bacteria, those species with peptidoglycan outer layers, are easier to kill-their thick peptidoglycan layer absorbs antibiotics and cleaning products easily.

Detailed explanation-3: -Antibiotics are chemicals that kill or inhibit the growth of bacteria and are used to treat bacterial infections. They are produced in nature by soil bacteria and fungi.

Detailed explanation-4: -Moist heat is generally more effective than dry heat for killing microorganisms because of its ability to penetrate microbial cells. Moist heat kills microorganisms by denaturing their proteins (causes proteins and enzymes to lose their three-dimensional functional shape).

Detailed explanation-5: -Antiseptic: destruction of vegetative pathogens on living tissue (not endospores).
