A. Contamination of organic debris such as blood decrease the effectiveness of the antimicrobial agent.
B. Some agents kill by denaturing microbial cell proteins.
C. Alcohols are most effective at a 50-70% aqueous solution.
D. Biofilms increase the effectiveness of antimicrobial agents.
E. Some agents inactivate microbes by attacking cell membrane lipids.
Question 3
Which of the following statements regarding microbial death is FALSE? Question options: cell walls are targeted by many microbial control agents the effectiveness of an antibacterial agent is a funciton of its microbial death rate the rate at which microbes are killed is termed the microbial death rate all of these statements are TRUE few antimicrobial agents function through the disruption of protein structure under a given set of conditions, the fraction of a microbial population that dies per minute is typically constant over time
Answer to question 1
EXPLANATION.
Virus have machinery in them to replicat and survive there by making them resistance to antimicrobial control agent.They are not easily inactivated by antimicrobial agents.
Answer to question 2
The correct answer is option D. Biofilms increase the effectiveness of antimicrobial agents. Biofilms are thin slimy layers of microorganisms formed when they adhere to wet surfaces. By forming a biofilm, the microorganisms are able to increase their resistance to antimicrobial control agents as well as host defenses and antibiotics.
