What does their very own name mean?
There is a lot of confusion in the naming of Salmonella pressures (even the folks who work on Salmonella are confused! ) but in importance, the traces which all of us will cope with here are generally different serovars of Salmonella enterica.
This means that they all belong to the genus Salmonella, a division that groups related, though not really identical bacteria together. These types of bacteria will be named after the scientist who discovered them, Dr . Daniel Salmon. The majority of the components of these types of bacteria will be identical, and at the GENETICS level, they are really between 95% and 00% identical. (As a comparison Elizabeth. coli and Salmonella, that are closely associated with each other, will be about 60-70% identical in the DNA level).
As their identity suggests Salmonella enterica are involved in causing conditions of the intestines (enteric means pertaining to the intestine). Three main serovars of Salmonella enterica happen to be Typhimurium, Enteritidis, and Typhi. Each of these is discussed even more below. These types of distinctions will be are designed to help scientists separate similar bacteria from the other person in papers and when discussing the inherited genes.
To confuse matters, serovars of Salmonella enterica could be subgrouped even more by " phage type". This technique uses the specificity of phage to separate between really closely related bacteria. Generally these bacteria are no difference by other means, and indeed, the reasons intended for the differences in phage specificity are often unfamiliar.
Salmonella enterica serovar Typhi. (Also known as Salmonella Typhi or abbreviated to S. Typhi) This kind of bacterium may be the causative agent of typhoid fever. Though typhoid fever is not really widespread in america, it is very prevalent in under-developed countries, to result in a serious, typically fatal disease. The symptoms of typhoid fever include nausea, vomiting, fever and loss of life. Unlike the other Salmonella discussed under, S. Typhi can only invade humans, with out other host has...
