Is Salmonella and salmonellosis is the same type of foodborne illness?
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 stool (feces). Humans become infected most frequently through contaminated water or food.
What is the common name for salmonellosis?
In humans, Salmonella are the cause of two diseases called salmonellosis: enteric fever (typhoid), resulting from bacterial invasion of the bloodstream, and acute gastroenteritis, resulting from a foodborne infection/intoxication.
What is the difference between the two types of Salmonella?
Salmonella serotypes can be divided into two main groups—typhoidal and nontyphoidal. Nontyphoidal serotypes are more common, and usually cause self-limiting gastrointestinal disease. They can infect a range of animals, and are zoonotic, meaning they can be transferred between humans and other animals.
How does Salmonella cause salmonellosis?
Salmonella is spread by the fecal-oral route and can be transmitted by • food and water, • by direct animal contact, and • rarely from person-to-person. An estimated 94% of salmonellosis is transmitted by food. Humans usually become infected by eating foods contaminated with feces from an infected animal.
