Expert Solution

Answer 6. Phagocytes. These are the cells that endulf foreign particles and injest, digest and kill most bacterial particles. RBC help to carry oxygen, reticulocytes are immature RBCs and resistant cells are cells that show resistance to certain drugs and chemicals.

Answer 7. LD50 also known as lethal dose 50 or lethal concentration 50(LC50 ). This is the required dose given to a test population that kills 50% of the population to study the virulence of the pathogen.

Answer 8. Exotoxins is the correct answer. These toxins are released by pathogens during normal growth. Endotoxins are released only during death of the pathogen cell.

Answer 9. Correct answer is Bacteremia. It is the condition when bacteria are shed in the bloodstream and when distributed to other body parts do not reproduce in the blood.

Answer 10. Correct answer is Systemic infection. In systemic infection the pathogen spread throughout the body from the affected part. Septicemia is a condition where pathogens from bacterial infected region enter blood and can spread throughout the body.

Thank you. Please provide a Thumbs up.
