Student Learning Outcomes -
  • Know and explain the basic pathophysiology of the common diseases of domestic animals.
  • Identify common ecto- and endoparasites of domestic animals and explain the clinical significance of each to veterinary patients.
Description -
Advanced study of the common diseases of domestic animals with emphasis on the dog and cat. Practical medical microbiology, clinical immunology. Mechanisms of disease; the host-parasite relationship and adaptive and maladaptive responses of the host. Etiology, pathogenesis, clinical signs and clinical management of selected immunological, viral, bacterial, fungal, and parasitic diseases. Etiology, pathogenesis, clinical signs and clinical management of selected developmental, degenerative, nutritional, metabolic, endocrine, immune-mediated, and neoplastic diseases. Principles of vaccination, disease prevention, public health, client education, and zoonosis. Diagnostic techniques, including gross and microscopic identification of common veterinary pathogens. Intended for students in the Veterinary Technology Program; enrollment is limited to students accepted in the program.

Course Objectives -
The student will be able to:
  1. discuss homeostasis and the normal, adaptive response of the host to stress, and the evolution of disease.
  2. describe and integrate principles of homeostasis, inflammation, non-specific host defenses, and specific immunity as the relate to host defense.
  3. discuss the basic principles of specific immunity in relation to vaccination and immune disorders.
  4. demonstrate a sound, basic knowledge of infectious and parasitic diseases of domestic animals, including etiology, mode of transmission, natural history or life cycle, pathogenesis, clinical signs, diagnostic procedures and clinical management.
  5. Know and explain the etiology, pathogenesis, clinical signs and clinical management of selected developmental, degenerative, nutritional, metabolic, endocrine, immune-mediate, and neoplastic diseases.

  7. recognize common signs of disease and clinical syndromes.
  8. memorize and identify common organisms by gross and microscopic examination.
  9. Relate aspects of clinical diseases to the practical clinical laboratory techniques and procedures, and the routine in-house diagnostic tests currently available.
  10. integrate principles of preventative medicine, therapeutics, client education, and public health as they pertain to the animal diseases presented.
  11. demonstrate the ability to use the appropriate vocabulary when relating to other medical professionals compared to laymen.
  12. manifest improvement in oral communication, writing, and library skills.
