Answer 1

1. The correct answer is A) Infectious Dose. The infectious dose is the number of microbes that will cause infection in a host.20. The correct answer is C) Adhesion-Process by which microorganisms attach themselves to cells. This statement is incorrect because adhesion is not a process by which microorganisms attach themselves to cells, but rather a process by which they attach to surfaces or other cells.21. The correct answer is B) False. Endotoxins are secreted only by gram-negative bacteria, not gram-positive bacteria.22. The correct answer is B) False. Antibody variation is called antigenic variation, not when a pathogen alters its surface antigens to escape attack by antibodies and immune cells.23. The correct answer is C) Viruses. Viruses are not a source of antibiotics.24. The correct answer is E) All of the above are related. All of the listed mechanisms are related to the action of antibiotics.25. The correct answer is B) False. Bactericidal compounds kill bacteria, not just inhibit their growth.26. The correct answer is A) True. The antimicrobial spectrum of an antibiotic refers to the range of microorganisms it can kill or inhibit.27. The correct answer is A) True. Antibiotic synergy refers to the phenomenon where two or more antibiotics work together to produce a more potent effect than if each antibiotic were applied individually.28. The correct answer is A) True. Microbial contamination in medicine is a significant concern during pharmaceutical manufacturing.29. The correct answer is D) All of the above are related. All of the listed options are related to control procedures in pharmaceutical manufacturing.30. The correct answer is C) Microbiological Limit Test. This test is used to determine the presence and quantity of microorganisms in drugs that do not have to be sterile.
