Flash Chlorination And Typhoid

Here is a basic rundown of how our water treatment process works. When the raw water first enters our plant a coagulant is added to help bond together the solids that are in the water. Also a small amount of fluoride is added, and pre-chlorination occurs. Once the chemicals are added, the water travels through 2 flash mixers that make sure the ...

Jun 10, 2020 Typhoidal and non-typhoidal Salmonelleae NTS cause typhoid fever and gastroenteritis, respectively, in humans. Salmonella typhoid toxin contributes to typhoid disease progression and chronic infection, but little is known about the role of its NTS ortholog. We found that typhoid toxin and its NTS ortholog induce different clinical presentations.
