LEARNING OBJECTIVES
After reading this chapter, you should be able to:
• Explain why defects in the immune systems resulting from many forms of
damage (secondary immunodeficiencies) are not uncommon in domestic
animals.
• Describe how the most significant causes of secondary immunodeficiencies are
viral infections.
• Describe the pathogenesis of FeLV- and FIV-induced immunodeficiencies.
• Summarize the data indicating that some environmental toxins and drugs are
immunosuppressive.
• Explain how malnutrition due to starvation, vitamin deficiency, or obesity can
significantly impair immune functions.
