Answer 1

1. Resident biota is absent from the Central Nervous system.

2. An example of an exogenous pyrogen is Endotoxin.

3. Two children attend the same preschool, but one child is at the facility on Mondays and Wednesday, while the other child attends the facility on Tuesdays and Thursdays. Both children become ill with Erythema infectiosum within a day of each other. The transmission is called Fomite transmission.

4. The index case is the first case found in an epidemiological investigation. This statement is True.

5. The ability of a microorganism to cause disease is called Pathogenicity.

6. A mechanical vector is a passive animal transporter of pathogens.

7. Indirect contact transmission occurs when pathogens are spread from one host to another inanimate object inadvertently used to transfer pathogens. These are called Fomite.

8. Bacterial contaminants can grow in food in a closed container. Someone can develop food poisoning after eating food from the container that was opened and heated because bacteria were producing an exotoxin.

9. The degree of a microorganism's capability to cause disease is called virulence.

10. The virulence factors produced by Staphylococcus aureus that enables it to invade the body is immune system.

11. External and physical barriers are the components of the body's first line of defense.

12. Internal components are the components of the body's second line of defense.
