“…Besides eggs and poultry meat, pork is one of the most important sources of human infection [21,36]. In order to prevent human disease due to the consumption of Salmonella contaminated pork, many studies have focussed on the epidemiology and the control of Salmonella in finishing pigs [5,18,23,34,35].…”

Salmonella in sows: a longitudinal study in farrow-to-finish pig herds

-Besides finishing pigs, sows are also believed to be important in the epidemiology of Salmonella. The study objective was to investigate the prevalence of Salmonella excretion in sows during an entire reproductive cycle. In 3 farrow-to-finish herds, groups of 34, 40 and 32 sows, respectively, were sampled serially. Faecal samples, environmental swabs and feed samples were taken and submitted to a qualitative Salmonella isolation. All isolates were characterised using RAPD and a representative number of isolates was serotyped. The prevalence of Salmonella excretion was < 10% during gestation, around farrowing and during lactation, but a significant increase in the number of Salmonella excreting sows was found in herds A (p < 0.01) and C (p = 0.02) after weaning. S. Infantis was the most prevalent serotype in herd A, S. Derby in herds B and C. Except for the S. Infantis group in herd A, all isolates within each group of the RAPD analysis belonged to the same serotype. Three sows in herd A and 1 sow in herd C shed different serotypes at different time points. The present results indicate that sows can maintain Salmonella infections in farrow-to-finish herds and that culled sows, leaving the herd after weaning, may constitute a substantial risk for contamination of their carcasses with Salmonella.

“…Salmonella is an enteric pathogen that colonizes the intestinal tract of a variety of animals, especially humans and poultry, and accounts for millions of cases of gastroenteritis and food-borne illness each year [1,2] . Salmonella enteritidis (S. enteritidis) can be transmitted to humans through the food production chain, and undercooked or raw eggs and poultry meat are a particularly high risk for humans [3] .…”

cecum, without causing apparent symptoms. By 5 d post inoculation, the cecum had significantly higher numbers of S. enteritidis than any of the other areas (P < 0.01), and this appeared to reflect its function as a repository for S. enteritidis. CONCLUSION:The results provided significant data for clarifying the pathogenic mechanism of S. enteritidis in the gastrointestinal tract, and showed that the jejunum, ileum and cecum are the primary sites of invasion in normal mice after oral infection. This study will help to further understanding of the mechanisms of action of S. INTRODUCTIONSalmonella is an enteric pathogen that colonizes the intestinal tract of a variety of animals, especially humans and poultry, and accounts for millions of cases of gastroenteritis and food-borne illness each year [1,2] . Salmonella enteritidis (S. enteritidis) can be transmitted to humans through the food production chain, and undercooked or raw eggs and poultry meat are a particularly high risk for humans [3] . In the last few decades, S. enteritidis has emerged as a major cause of food-borne illness worldwide. As a result of the increased prevalence of S. enteritidis and its complex life cycle, identifying the regular distribution pattern of S. enteritidis in the gastrointestinal tract will help to understand its mechanism of action.Previous studies have shown that orally introduced S. enteritidis has a rapid transit time through the intestine, and a small proportion of the inoculum establishes itself within the walls of the small intestine and cecum several enteritidis. We used this assay to detect genomic DNA of S. enteritidis in the gastrointestinal tract, including duodenum, jejunum, ileum, cecum, colon, rectum, esophagus and stomach, from mice after oral infection.
