What is Salmonella Typhi?

Salmonella is the president of many species of Salmonella. Salmonella is a major killer that causes food poisoning. It belongs to the Enterobacteriaceae family and can cause diseases in humans, poultry, mice and livestock, and can also contaminate human food. Salmonella can multiply in large numbers and contaminate food sources. Typhoid Salmonella only infects humans, damaging the liver, spleen, stomach and bone marrow. Let’s take a look at the specific content of Salmonella Typhi.

Salmonella typhi, which infects only humans and damages the liver, spleen and bone marrow, sickens 16 million people and kills 600,000 each year, a situation that is likely to get worse as more strains become resistant to antibiotics. Salmonella typhimurium is not very picky about its living environment and can infect almost all living things that walk or crawl on the ground. The symptoms it causes in humans are generally food poisoning (people who like to eat raw eggs should be careful), which does not sound as scary as typhoid.

But some scientists believe that it poses a greater threat. The actual number of food poisoning incidents caused by it may be 30 times more than the reported number. Hundreds of millions of people are infected every year, and the death toll is twice that of typhoid Salmonella, mainly infants, young children and the elderly.

The Cambridge SANGER Center - the same center, and even the project leader is the same person as the plague bacillus mentioned above - obtained a strain of Salmonella typhi from Vietnam that is resistant to multiple antibiotics. Sequencing revealed that there are more than 200 pseudogenes in its genome.

They once served a purpose but were discarded as the bacterium adapted to living in the human body—and this may have forced it into an evolutionary dead end. Scientists hope that this single taste will make it easier to deal with, and that by blocking the pathway by which it infects humans, the disease may be eradicated.

The above is some relevant content about Salmonella typhi. Food poisoning caused by Salmonella is no different from ordinary food poisoning. Salmonella is not easy to reproduce in water, so the protection of food is particularly important. It can be stored in a low temperature place and heated to kill Salmonella, so as to prevent food poisoning.
