This book is intended to provide an update on recent advances in the field of diagnostics to benefit the scholars’, teachers and scientists working in the area of Molecular Biology. The book is a compilation of invited papers on various aspects of Advanced Diagnostic Techniques in Veterinary Science. The contributors have been chosen based on their expertise in the field. However, owing to the enormity of the field of diagnostics it was rather impossible to include every topic. Nevertheless, sincere effort has been made to include major topics of the recent concern. The articles presented in this book are either original publication of the author or have been compiled from the literatures. This book would serve as the bench top reference for scholars, teachers and researchers of the veterinary science to provide a glimpse of New Horizons in Veterinary diagnostics. We are hopeful that the various chapters covered in this book will be immensely beneficial to the scientific fraternity in general and students in particular.
