POST-VACCINATION IMMUNITY IN ARCTIC FOXES VACCINATED AGAINST SALMONELLA
Combating salmonellosis has always been an important task. This infection has been widespread among farm and fur animals, as well as poultry, and tends to be on a rise lately. Furthermore, 85 % of animals continue to carry the bacteria after recovery. Salmonellosis outbreaks are registered among fur...

Combating salmonellosis has always been an important task. This infection has been widespread among farm and fur animals, as well as poultry, and tends to be on a rise lately. Furthermore, 85 % of animals continue to carry the bacteria after recovery. Salmonellosis outbreaks are registered among fur animals from early April to late September. In some farms, mortality is up to 30 %. As a result, epizootic hotbeds of salmonella infection are persistent. It is therefore important to take timely and specific actions to prevent, reduce and eliminate animal losses to salmonellosis.
