salmonellosis. In salmonellosis. S. choleraesuis causes blood poisoning in some hogs but is latent in others, which act as carriers. Apparently healthy pets—e.g., dogs, cats, and turtles and other reptiles—can, through close contact, transmit salmonellosis to humans.
During his first 2 years at BAI, Smith discovered a new species of bacteria (Salmonella enterica, formerly called Salmonella choleraesuis), which he thought was the cause of hog cholera.
Since then, as a result of experiments indicating a high degree of DNA similarity, all Salmonellaisolates were classified in a single species, Salmonella choleraesuis(42, 51, 135). This species was subsequently subclassified into seven subgroups based on DNA similarity and host range (51, 135).

Starting from the outside of the cell, one of first characteristics of Salmonella is the flagella. This is a long tail-like structure, seen in Figure 1 2, that enables the cell to move about in...
Salmonella choleraesuis infection: An infection caused by bacteria from the Salmonella genus which mainly causes gastroenteritis. Infection is caused by consuming contaminated food or drinks. Infection is caused by consuming contaminated food or drinks.
CHARACTERISTICS: Salmonella enterica is one of two Salmonella species (enterica and bongori) and a member of the Enterobacteriaceae family (1, 2). Salmonella enterica spp. is subdivided into 6 subspecies (enterica (I), salamae (II), arizonae (IIIa), diarizonae (IIIb), houtenae (IV) and indica (VI) ).
Overview Salmonella infection (salmonellosis) is a common bacterial disease that affects the intestinal tract. Salmonella bacteria typically live in animal and human intestines and are shed through feces. Humans become infected most frequently through contaminated water or food.
Salmonella, (genus Salmonella ), group of rod-shaped, gram-negative, facultatively anaerobic bacteria in the family Enterobacteriaceae. Their principal habitat is the intestinal tract of humans and other animals. Some species exist in animals without causing disease symptoms; others can result in any of a wide range of mild to serious infections termed salmonellosis in humans.
Initially, Salmonella Choleraesuis was thought to be the causative agent of hog cholera, so Salmon and Smith named it "Hog-cholerabacillus". The name Salmonella was not used until 1900, when Joseph Leon Lignières proposed that the pathogen discovered by Salmon's group be called Salmonella in his honor.
