What Are the Signs of Salmonella Food Poisoning?

Salmonella is an important genus in the family Enterobacteriaceae. Salmonella is a gram-negative bacillus, which is aerobic or facultative anaerobic, and most of them have perianal flagella and can move. There are currently more than 2,300 serotypes in the world, and more than 200 have been found in China. According to the differences in the structure of the O antigen, Salmonella is divided into A, B, C1, C2, C3, D, E1, E4, F, etc. Among them, Salmonella that is pathogenic to humans only accounts for a few. The host specificity of Salmonella is very weak, it can infect both animals and humans, and it is easy to cause human food poisoning. The most pathogenic are Salmonellacholerae swine, followed by Salmonellatyphimurium and Salmonellaenteritidis ^[1] .
