Evolving importance of biologies and novel delivery systems in the face of microbial resistance

Abstract

Methods to control infectious diseases in livestock are growing in importance. As the size of the average farm increases-for poultry, dairy and beef cattle, swine, and fish-the risk of rapid spread of infectious diseases increases as well. This increases the need for alternative methods of control of infectious agents. Improvements in specific immunogens, adjuvants, and delivery systems are needed to meet the demand for vaccines to ensure a healthy and safe meat supply. This article explores the challenges, trends, and recent advances in the control of infectious diseases through the use of biologies.
