History of Vet Pathology
Veterinary pathology has a long history dating back to ancient Greece where animal dissection was used to further the understanding of human anatomy and disease, laying the foundation for the field. Rudolf Virchow, considered the father of modern pathology, studied disease through visits to abattoirs and implemented meat inspection by early veterinary pathologists. While the 1800s saw greater progress in human pathology, pioneers in Germany and Austria began establishing veterinary pathology as a legitimate field through systematic necropsy procedures and descriptive guides of animal disease.

Veterinary General Pathology
Another feature of the book is that wherever considered appropriate aspects of human pathology have been narrated side by side. The text will therefore act as a useful exercise in comparative pathology. As such the book may serve as a good reference for medical dentistry and zoology students. In fact it should prove useful to workers in all branches of science who wish to learn about the basic disease processes.
