Viewing: What is Salmonella

Salmonella bacteria is a type of bacteria that can cause a disease in the digestive tract of humans and animals called Salmonella infection. Although rare, the harmful effects of salmonella can be transmitted from the intestines to the bloodstream and to other places in the body.

Salmonella infection is an infection of Salmonella bacteria in the stomach and intestines. This disease is similar to gastritis. Most patients with mild infections clear up on their own in 4 to 7 days without treatment. Salmonella bacteria, also known as typhoid bacteria, include S. typhi and S. paratyphi A, B, C all strains are capable of causing typhoid.

Typhoid bacteria enter the body’s digestive system, after death, it will release endotoxins. The more Salmonella bacteria die, the more toxins they release to attack the infected person’s body. The endotoxins of salmonella bacteria cause very bad effects in the intestines, the endotoxins will damage the intestinal lining (irritation of the intestines causing abdominal pain, bleeding, or possibly perforation). The endotoxin released by salmonella bacteria enters the bloodstream to the central nervous system, causing nervous system damage and systemic toxicity.

Salmonella bacteria have good vitality and resistance. This bacterium is cold tolerant, in ice water for 2-3 months, in plain water for > 1 month, in vegetables for 5-10 days, in feces for 1 to several months. Salmonella bacteria are killed at a temperature of 55 degrees C/30 minutes, alcohol at 90 degrees C/several minutes, common disinfectants kill bacteria easily (chloramin 3%, phenol 5%).

In rare cases, Salmonella infection can be fatal if the person is not treated promptly and correctly. However, there are some people who are infected with Salmonella, but because the body already has antibodies, the number of bacteria is small and the virulence of the bacteria is weak, so they may have digestive disorders for a few days and then go away on their own. A very small number of them become carriers of the bacteria, which can last for many months.
