Zoonotic diseases are mostly caused by bacterial, viral or parasitic agents; even though, unusual agents such as prions could also be concerned in causing zoonotic disorders. Many of the zoonotic diseases are a health concern for the public, but also influence the manufacture of animal source foods. Hence, they can cause difficulties in the global trade of animal-origin goods. The main issue contributing to the appearance of new zoonotic pathogens in human population is the augmented contact between humans and animals. This book gives a helpful insight on zoonosis and will prove beneficial for readers interested in this field.
