- Why can Koch’s Postulates NOT be used to determine causative agent of AIDS? How was it determined that HIV causes AIDS?
- Watch the video “HIV Life Cycle” at https://www.biointeractive.org/classroom-resources/hiv-life-cycle. List 3 virulence factors of HIV and explain in which stage of pathogenesis (exposure, adhesion, invasion, infection, and transmission) the virulence factors are used.
Homework Answers
Many viruses do not cause illness in all infected persons, a requirement of postulate #1. Poliovirus, which causes paralytic disease in about 1% of those infected. Infection with the same virus may lead to markedly different diseases, while different viruses may cause the same disease. Postulates #2 and #3 cannot be fulfilled for viruses that do not replicate in cell culture, for that a suitable animal model has not been identified.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
