Vet Tech Immunology Term 1 Exam Questions and Answers 2026 (39 Questions) | Hypersensitivity, Immunoglobulins, Vaccines, Passive Immunity & AIHA | Veterinary Technology

This comprehensive Vet Tech Immunology Term 1 revision guide contains 39 expertly verified exam questions and answers covering the foundational concepts of veterinary immunology commonly assessed in Veterinary Technology programs. Organized in a concise question-and-answer format, this high-yield study resource is designed to strengthen active recall, reinforce lecture content, and improve examination performance for students preparing for immunology assessments and veterinary certification examinations. The material provides an in-depth review of innate and adaptive immunity, emphasizing the cells, proteins, and physiological mechanisms involved in host defense. Students will strengthen their understanding of the roles of neutrophils, monocytes, lymphocytes, plasma cells, erythrocytes, basophils, eosinophils, and natural immune barriers such as the skin and mucous membranes. Core concepts including specific versus non-specific immunity, inflammation, complement activation, interferon activity, phagocytosis, and the distinctions between humoral and cell-mediated immunity are thoroughly explored. The guide also reviews lymphocyte differentiation, including the development of plasma cells and memory B cells, as well as helper, suppressor, and cytotoxic T lymphocytes. Extensive coverage is devoted to immunoglobulins and their clinical significance in veterinary medicine. Students will review the structure and function of antibodies, including IgA as the predominant immunoglobulin of mucosal surfaces, IgE in allergic and anaphylactic reactions, and IgM as the first antibody produced following antigen exposure. The document further examines antigen recognition, antibody production, histamine release, and the role of antibodies in protecting against infectious agents. A major focus of this revision guide is hypersensitivity and immune-mediated disease. Learners will examine Type I hypersensitivity reactions associated with urticaria and anaphylaxis, autoimmune hemolytic anemia (AIHA) as a Type II hypersensitivity disorder, and the use of the Coombs test in diagnosing immune-mediated destruction of erythrocytes. Emergency treatment protocols for anaphylactic reactions, including the administration of epinephrine and diphenhydramine, are also reviewed. The vaccination and neonatal immunity section provides detailed coverage of passive immunity, colostrum transfer, and failures of passive transfer in neonatal patients. Topics include the importance of early colostrum intake, species-specific considerations such as the horse's complete reliance on colostrum-derived antibodies, and factors leading to inadequate passive immunity. Students will also review vaccine classifications frequently encountered in veterinary practice, including modified-live vaccines, bacterins, recombinant vaccines, killed vaccines, and toxoid preparations. Clinical examples include DHPP, leptospirosis, FeLV, rabies, and tetanus vaccines. This study resource is ideal for examination preparation, rapid revision before assessments, and reinforcing the immunological principles essential to Veterinary Technology practice. The question-and-answer format enables learners to identify knowledge gaps quickly and focus on high-yield concepts frequently tested in veterinary curricula.
