Questions and Answers
What is the main difference between opportunistic and primary bacterial pathogens?
What is the main difference between opportunistic and primary bacterial pathogens?
- Opportunists are usually exogenous, while primary pathogens are usually endogenous
- Opportunists require a larger infectious dose (ID) compared to primary pathogens
- Opportunists only cause disease in compromised hosts, while primary pathogens can cause disease in both healthy and sick individuals (correct)
- Opportunists primarily enter through specific portals, while primary pathogens can enter at a variety of portals
What is the significance of the infectious dose (ID) for pathogens?
What is the significance of the infectious dose (ID) for pathogens?
- It determines the speed at which a pathogen can spread within a host
- It represents the minimal number of pathogens needed to cause disease (correct)
- It indicates the maximum number of pathogens a host can tolerate
- It reflects the resistance of a pathogen to antibiotics
How do portals of entry relate to the ability of pathogens to cause disease?
How do portals of entry relate to the ability of pathogens to cause disease?
- Portals of entry determine the type of toxins produced by the pathogens
- Pathogens that have adapted to a particular portal have a higher infectious dose
- Portals of entry are the same anatomical regions which support normal flora (correct)
- The size of inoculum is not influenced by the portals of entry
