1. What is a true pathogen and who does it typically infect? What is an opportunistic pathogen and who does it typically infect?

Explain the term pathogens.

What is the “iceberg concept of infection.” How does this affect our understanding of the mortality rates of a particular microbe?

What are healthcare-associated infections?

2.1. Explain the characteristics of bacteria and viruses that make them pathogens Explain how pathogens spread between people Explain the characteristics of bacteria and virus that make them pathogens. Explain how pathogens can be transmitted from person to person.

Identify adaptations that have contributed to pathogen success.

Which of the following is a reason that specific pathogens tend to infect specific tissues? Most tissues are resistant to microbial exotoxins   There are chemical and physical differences between tissues.   Microbes preferentially target external tissues, such as skin, as the environment is more favorable for their growth than inside the body.   Tissues with neutral pH are colonized but those with acidic or alkaline pH are not.

Explain the relationship between the infection chain and transmission of infection ?

To combat the virulence and transmission of a disease, health care officials sometimes discuss “disease control methods.”  What are some such methods that we have been seeing recently?

What factors are important in the emergence or reemergenceof potential pathogens?
