Answer 1

The Salmonella bacterium (The fluid which bacteria prevent itself ) was first described by Theobald Smith (1859-1934) and Daniel Elmer Salmon in 1885 in a strain isolated from pigs with hog cholera, in the paper Investigations on Swine Plague, published in the Second Annual Report of Bureau of Animal Industry. Salmon termed it Hog-cholerabacillus. It is now called Salmonella cholera suis, but is not the real cause of swine plague, which is a viral disease. Salmonella was first discovered by Theobald Smith.

It was the French bacteriologist Joseph Léon Marcel Ligniéres (1868-1933) who, in 1900, suggested that the entire group of bacteria to which the swine pest bacillus belongs, should be termed Salmonella in honour of Salmon.
