Salmonellosis in pigs

Importance

Salmonella infections pose a serious threat to human and animal health.

Salmonella infections in humans are usually food-borne. In Germany, they are classed as notifiable diarrhoeal diseases under the Infektionsschutzgesetz (Protection against Infection Act). The Gram-negative bacteria are largely species-specific but nevertheless have zoonotic potential and can be transmitted from animals to humans and vice-versa.

Salmonella (S.) typhimurium is particularly important here, as it has significant zoonotic potential and is one of the main causes of human gastroenteritis. This pathogen has become increasingly widespread on pig farms and is now the most commonly detected serovar. Preventive measures should therefore start on the breeding farm. One such measure is the vaccination of sows and piglets using a live vaccine against S. typhimurium available from IDT Biologika Animal Health. Vaccination can greatly reduce the shedding of pathogens and hence the pressure of infection, thereby limiting transmission.
