Day’s Veterinary Immunology: Principles and Practice
- Brian Catchpole and Harm HogenEsch 3rd edition

The legacy of excellence, modernized for the next generation. The 3rd edition of this landmark text remains the premier visual guide to the animal immune system. By bridging the gap between complex molecular pathways and daily clinical reality, it provides a "living" look at how animals defend themselves, how vaccines work, and why the immune system sometimes turns against the body.
