Pandemic   b. Endemic   c. Epidemic   d. Zoonotic-                      Identify and categorize each of the following by the unique characteristics and identifying traits:o   a. Bacteria   b.  Viruses   c.  Fungi   d.  Protozoa   e.  Helminth-                      Define a prion and explain the characteristics that make this class of pathogens unique.-                      Compare and contrast prokaryotic and eukaryotic organisms.-                      Summarize how to classify bacteria, including by shape, aerobic/anaerobic, and by gram stain.-                      Compare and contrast the differences between gram negative and gram positive bacteria, particularly in regards to cell membranes and cell walls, susceptibility to antibiotics, and endotoxins vs. exotoxins.-                      Compare and contrast the properties of endotoxins vs. those of exotoxins.-                      Summarize the properties of peptidoglycan and relate how these properties affect the susceptibility of some bacteria to antibiotics.-                      Summarize the properties and characteristics of the membrane outside of the cell wall of some bacteria in regards to susceptibility to antibiotics, infection of a host, and resistance to host defenses.-                      Summarize how a bacterial infection can lead to the death of a host via sepsis and septic shock.-                      Explain why a virus is not considered to be a living species.-                      Summarize how viral reproduction occurs.-                      Compare and contrast a retrovirus to a standard virus.-                      Identify the kingdom of life in which fungi are classified.-                      Summarize the key traits of protozoa.-                      Explain how the symptoms diseases caused by helminths differ from many other pathogens.-                      Outline the method by which a prion causes a disease and identify practices that increase the likelihood of a prion infection.-                      Describe the existing treatments and/or cures for a prion disease.-                      Summarize the mechanisms and strategies that comprise each of the following: a. continual forms of nonspecific immunity; b. selective forms of nonspecific immunity; c. specific immunity.-                      Compare and contrast the properties of the three kinds of continual nonspecific immunity, including: a. mechanical; b. physical; c. chemical. -                      Summarize the identifying characteristics of all forms of selective nonspecific immunity, including: a. Phagocytosis  b.  Inflammation  c.  Pyrexia  d.  Protective proteins  e.  NK Cells-                      Summarize the function of interferons and complement proteins.-                      Summarize how specific immunity differs from all forms of nonspecific immunity.-                      Explain how the body uses antigens and antibodies to fight a disease.-                      Identify the key traits that comprise each of the following: a.   Genetic specific immunity    b.  Acquired specific immunity   c.  Nonspecific immunity-                      Summarize the difference between active acquired immunity and passive acquired immunity.-                      Explain how a vaccination works to reduce the rate of contraction of a disease.-                      Identify the key characteristics of each of the following kinds of vaccinations:o   a. Live    b.  Killed/Inactivated   c.  Toxoid   d.  Biosynthetic-                      Define colostrum, and explain why it is a valuable part of a production animal operation.-                      Summarize why adult vaccination is necessary for herd health using examples.-                      Define VCPR and explain why it is necessary for an animal operation.-                      Compare and contrast the function and properties of antibiotics and vaccines.-                      Describe the most common methods by which an antibiotic destroys bacteria.-                      Describe the most common bacterial mechanisms of antibiotic resistance.-                      Summarize the difference between Inherent (natural) Bacterial Resistance and Acquired Resistance.
