Salmonellae are commonly occurring and are prevalented all through the world. They are closely related to escherichia.

They get differenced in enteritis-salmonellae and typhus / paratyphus salmonellae. Typhoid Salmonellae only occure in human-beings and not in animals.
Similar to other intestinal infections salmonellosis causes disorders in the application of food, which result in heavy economic losses for animal husbandry.

Seeing that salmonellae could attack the health of human beings and animals, they belong to zoonosis.
As a rule salmonellae effect diarrhea and are verifiable in dried feces for more than 2,5 years.
