Salmonella can pass through the entire food chain from animal feed, primary production, and all the way to households or food.
Non-typhoidal Salmonella is the most common form, and is carried by both humans and animals. Most serotypes of Salmonella, such as Salmonella Javiana and Salmonella Enteritidis cause non-typhoidal Salmonella. Typhoidal Salmonella, which causes typhoid fever, is rare, and is caused by Salmonella Typhi, which is carried only by humans. Consumption of contaminated foods typically causes Salmonella infection salmonellosis. Read about symptoms and treatment of this common form of food poisoning, find out if Salmonella is contagious, and read about current outbreaks. Occasionally, contaminated food usually handled by an individual who harbors S typhi may be the vehicle. Plasmid DNA fingerprinting and bacteria phage lysotyping of Salmonella isolates are powerful epidemiologic tools for studying outbreaks of salmonellosis and tracing the spread of. v. salmonelle e salmonellosi, App. III, II, p. 651 I microrganismi appartenenti al genere Salmonella sono ubiquitari anche se nelle diverse aree geografiche esistono notevoli differenze nella prevalenza dei diversi sierotipi, e sono patogeni per l'uomo e per gli animali, nei quali provocano solitamente una gastroenterite acuta, detta.
