Abstract
Simple SummarySalmonella enterica subsp. enterica derived from poultry meat is the primary cause of Salmonella infection in humans and the second most ubiquitous zoonosis in the European Union after campylobacteriosis. Wildlife animals and livestock can be a reservoir of Salmonella spp., and they can contribute to the persistence of bacteria in the environment. Salmonella spp. pathogens can also be a source of widespread infections in fur-bearing animals, such as foxes (Vulpes vulpes) and mink (Neovison vision). This study analysed the prevalence of Salmonella spp. in two Arctic fox (Alopex lagopus) farms and the correlations between animals that tested positive for Salmonella spp and breeding results. Salmonella Heidelberg, S. Saintpaul, and S. Reading were isolated. All three serotypes are typically isolated from commercial poultry flocks. In this study, Salmonella spp. increased the risk of female infertility, but further research is needed to confirm the results. This is the first report on the prevalence of S. Heidelberg, S. Saintpaul, and S. Reading in an Arctic fox (Alopex lagopus) population.The objective of the study was to determine the occurrence of Salmonella spp. infections in two Arctic fox (Alopex lagopus) farms in Poland, and to analyse the correlations between animals that tested positive for Salmonella spp and breeding results. Faecal samples were taken from 1094 clinically healthy blue foxes from the basic stock of farms A and B. Salmonella spp. were detected in 18.06% (56/310) of the samples collected in farm A and in 15.94% (125/784) of the samples collected in farm B. All isolated strains belonged to S. enterica subsp. enterica serotypes Salmonella Saintpaul (S. Saintpaul), Salmonella Reading (S. Reading), and Salmonella Heidelberg (S. Heidelberg). All three serotypes are typically isolated from commercial poultry flocks. Salmonella spp. infections significantly increased the risk of female infertility, but further research is needed to confirm the results. This is the first report on the prevalence of S. Heidelberg, S. Saintpaul, and S. Reading in faecal samples collected from Arctic fox (Alopex lagopus) farms in Poland.
Highlights
Salmonella enterica subsp. enterica derived from poultry meat is the primary cause of Salmonella infection in humans worldwide [1]
In 2018, 91,857 confirmed cases of Salmonella species infections were registered in the European Union (EU), making salmonellosis the second most frequently reported zoonosis in the EU after campylobacteriosis (N = 246,571) [2]

Summary
Salmonella enterica subsp. enterica derived from poultry meat is the primary cause of Salmonella infection in humans worldwide [1]. Enterica derived from poultry meat is the primary cause of Salmonella infection in humans worldwide [1]. In 2018, 91,857 confirmed cases of Salmonella species (spp.) infections were registered in the European Union (EU), making salmonellosis the second most frequently reported zoonosis in the EU after campylobacteriosis (N = 246,571) [2]. More than 2500 serotypes have been identified to date, but most human infections are caused by only several serotypes [3]. Salmonella spp. pathogens are transmitted through food of animal origin, such as eggs, chicken, pork, or beef [4]. Salmonella spp. can be transmitted between animal species and between animals and humans, including by vectors [5,6,7]. Salmonella spp. are excreted with the faeces of healthy animals
