Abstract:
Salmonella is an important foodborne pathogen and one of the main causes of diarrhea. Every year, about 550 million people suffer from diarrhea due to Salmonella infection, of which about 230 000 die. It has become a major global public safety issue. The application fields of Salmonella detection involve food safety, water quality monitoring, animal husbandry, public health monitoring, and medical diagnosis. The detection requirements mainly come from three aspects: pathogen identification, serotype identification, drug resistance and virulence identification. In recent years, the detection technology for Salmonella has made rapid progress, especially the emergence and development of emerging molecular detection technologies, providing new perspectives for Salmonella detection in different scenarios. However, due to the diversity of Salmonella serotypes and the complexity of detection scenarios, existing detection technologies still have some pain points (such as long detection time, cumbersome operation steps, low scene adaptability, etc.). This article will elaborate on the application of several emerging molecular detection technologies with distinct characteristics, such as CRISPR Cas technology, digital PCR technology, sequencing technology, and microfluidic technology, in Salmonella detection. It aims to provide a reference for the development and improvement of Salmonella detection technology and the establishment of infection warning and control systems.
