Question 1

Which type of culture media supports the growth of most non-fastidious bacteria?

Accepted Answer

General purpose (nutrient) media

Answer

General purpose media like nutrient agar or tryptic soy agar provide basic nutritional requirements to support the growth of most non-fastidious bacteria.

Question 2

Endotoxins are components of which bacterial cell structure?

Accepted Answer

Gram-negative outer membrane lipopolysaccharide (LPS)

Answer

Endotoxins are lipopolysaccharide (LPS) molecules found in the outer membrane of Gram-negative bacteria, released upon cell lysis and causing fever and septic shock.

Question 3

Which sterilization method is most suitable for heat-labile pharmaceutical solutions?

Accepted Answer

Filtration through 0.22 μm membrane

Answer

Membrane filtration through 0.22 μm filters removes microorganisms from heat-sensitive solutions without exposing them to high temperatures.

Question 4

MIC (Minimum Inhibitory Concentration) is defined as the lowest concentration of an antibiotic that:

Accepted Answer

Prevents visible bacterial growth

Answer

MIC is the lowest concentration of an antimicrobial agent that inhibits visible bacterial growth in a standardized susceptibility test.

Question 5

Which immune cells are primarily responsible for cell-mediated immunity against intracellular pathogens?

Accepted Answer
