Accurate Identification of Salmonella enterica in Calves

Abstract

Salmonella enterica is a bacterium that can cause serious infections in humans and animals, especially cattle. The identification and differentiation of S. enterica serotypes in cattle is important for epidemiological surveillance, disease prevention and control, and public health protection. However, the current methods and techniques for S. enterica detection have various challenges and limitations, such as low sensitivity and specificity, high cost and complexity, and the need for viable and pure bacterial cultures. Therefore, there is a need for further research and development of novel and improved methods and techniques that can overcome these challenges and provide reliable and accurate information on S. enterica serotypes in cattle. Such information can help to improve the understanding of the epidemiology, pathogenesis, and transmission of S. enterica in cattle, as well as to design and implement effective strategies for its prevention and control. This chapter reviews the current methods and techniques for S. enterica detection, such as culture-based methods, biochemical methods, molecular methods, phage-based methods, and biosensor methods, and discusses their advantages and disadvantages, as well as their future trends and perspectives.
