a genus of gram-negative, non-lactose fermenting, medium-sized, rod-shaped, bacteria, members of the family Enterobacteriaceae, most species having flagella and pili. The genus contains one species which has been divided into seven subgroups and a very large number of serotypes. Most species pathogenic for warm-blooded animals are in subgroup I (S. enterica). Subgroups IIIa (S. salamae) and IIIb (S. arizonae) include some species occasionally pathogenic for animals and birds. The salmonella include the typhoid-paratyphoid bacilli and bacteria usually pathogenic for lower animals but which are often transmitted to humans. They cause salmonellosis which has a number of manifestations and some are specific causes of abortion.

Salmonella abortusequi
causes abortion in horses.
Salmonella abortusovis, Salmonella montevideo
cause abortion in sheep.
Salmonella arizonae
the name now applied to subgroup IIIa, these organisms cause severe enteritis and septicemia in chicks and turkey poults.
Salmonella bovismorbificans
causes enteritis in cattle and horses.
Salmonella choleraesuis biotype Kunzendorf
causes septicemic and enteric salmonellosis of swine. Called the hog cholera bacillus because of the similarity of the clinical diseases.
Salmonella dublin
causes septicemia, meningitis, enteritis and abortion in cattle and abortion in sheep.
Salmonella enteriditis
a common cause of gastroenteritis in humans. Recorded also in most domestic animal species and fowl.
Salmonella gallinarum
causes fowl typhoid.
Salmonella heidelberg
an occasional isolate in horses.
Salmonella pullorum
Salmonella typhimurium
DT 104 R-types ACSSuT infects all animal species and humans, but particularly cattle and in many countries DT104 (determinant type/phage type 104) has emerged to be the most common phage type of S. typhimurium. Of concern as it is resistant to many of the commonly used antibiotics including ampicillin, chloramphenicol, streptomycin, sulphonamides, and tetracyclines (R-type ACSSuT). Some have also developed resistance to trimethoprim and to quinolone antibiotics (R-type ACSSUTTm and ACSSuTCP). The causative agent of mouse typhoid and of food poisoning in humans. Causes outbreaks of enteritis in most species, often related to rodent infestation. The cause of fowl paratyphoid.
Salmonella typhisuis
an uncommon isolate in pigs.
