Application of biosensors to detection of epidemic diseases in animals

Epidemic diseases are the leading cause of animal mortality, resulting in significant losses to the agricultural economy. These economic impacts have generated a strong interest in advancing methods for the diagnosis and control of epidemic diseases in animals. Conventional methods are often time-consuming (typically result is available in 2-10 days), expensive, and require both large-scale equipment and experienced personnel. However, the advent of biosensor technology has ushered in a new and promising approach for the diagnosis of animal diseases. With advantages that include simplicity, real -time analysis, high sensitivity, miniaturization, rapid detection time, and low cost, biosensor technologies are under active development for the diagnosis of epidemic diseases in animals. Here, we summarize recent developments in biological sensing technologies used to detect infectious viral, bacterial, and parasitic diseases. Additionally, we discuss research challenges and future prospects for this field of study.
