Overview
Historical Perspective
Salmonela was initially isolated from the intestines of pigs, by Salmon, an American veterinary pathologist. The bacteria was first associated with hog cholera by Theobald Smith in 1885. However, the disease was later discovered to be associated with a viral infection, with secondary infection due to Salmonella.
Typhoid fever was confused with typhus prior to the 19th century. It was only in 1829 that P. Luis, in Paris, after the studying the spleen and intestinal lymph nodes was able to distinguish typhoid from other types of fever. Additionally, P. Luis described the hemorrhage, intestinal perforation and rose spots related to the disease.
William Jenner, in 1850, was the first to question the difference between typhoid fever and typhus in the english literature. According to him, typhoid was associated with enlarged mesenteric lymph nodes and Peyer's patches.
