Veterinary Immunology and Infectious Diseases Review 2026 (49 Questions) | IMHA, Parvovirus, FeLV, FIV, FIP & Rabies | Veterinary Medicine

This comprehensive veterinary study guide contains 49 expertly verified exam-style questions and answers covering the fundamental principles of immunology and the diagnosis, treatment, and prevention of major infectious diseases encountered in veterinary medicine. Designed as a high-yield review resource, the material provides concise explanations of immune system function, innate and adaptive immunity, antigen-antibody interactions, immunoglobulin classes, immune-mediated disorders, and clinically relevant infectious diseases affecting companion animals. The review begins with the foundations of veterinary immunology, including the protective role of the immune system against pathogens, the distinction between self and non-self recognition, and the mechanisms underlying immune-mediated disease. Students will strengthen their understanding of innate immunity, adaptive immunity, immunological memory, phagocytosis, lymphocyte function, antibody production, and the clinical significance of major immunoglobulins including IgG, IgM, IgA, and IgE. The infectious disease section focuses on conditions frequently assessed in veterinary nursing and veterinary medicine examinations. Topics include the etiology, transmission, clinical presentation, treatment, prevention, and zoonotic importance of canine parvovirus (CPV-2), feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), feline infectious peritonitis (FIP), rabies virus, Babesia infections, and Mycoplasma infections. The document also provides detailed review of immune-mediated hemolytic anemia (IMHA) and immune-mediated polyarthritis, including diagnostic approaches, therapeutic interventions, and potential complications such as thromboembolism. This resource is particularly valuable for examination preparation, rapid revision before assessments, and reinforcement of core concepts taught in veterinary immunology, small animal medicine, infectious disease, and clinical pathology courses. The question-and-answer format promotes active recall and self-assessment, enabling students to identify knowledge gaps and improve retention of clinically important material.
