Longitudinal study of fecal Salmonella shedding by sows
نویسنده
چکیده
Materials and methods: A total of 166 sows at two farrow-to-finish farms in Italy were tested for Salmonella shedding at four stages of reproduction. Sows were divided into three groups: primiparous (farrowed one litter), pluriparous (two to five litters), and old sows (> 5 litters). Fecal samples were collected approximately 2 weeks before parturition (Late Gestation), 1 and 3 weeks after parturition (Postpartum One and Two), and 30 to 60 days postpartum (Postweaning). Environmental samples were collected from farrowing rooms, farrowing crates, and gestation pens before placement of sows.

Reduction of Salmonella Shedding by Sows during Gestation in Relation to Its Fecal Microbiome
Pork meat is estimated to be responsible for 10-20% of human salmonellosis cases in Europe. Control strategies at the farm could reduce contamination at the slaughterhouse. One of the targeted sectors of production is maternity, where sows could be Salmonella reservoirs. The aim of this study was to assess the dynamics of shedding of Salmonella in terms of variation in both shedding prevalence ...

A longitudinal study of the infection dynamics of Salmonella enterica was carried out with three Danish farrow-to-finish swine herds. To account for variations in Salmonella shedding over time, litters from each herd were divided into two cohorts. Each cohort consisted of 30 pigs, for a total of 180 pigs. Pigs were individually monitored by monthly bacteriologic and serologic examinations from ...

The current study investigated the effect of environmental stressors (i.e., weather changes) on Salmonella shedding in free-range production systems and the correlations with behavioral and physiological measures (i.e., fecal glucocorticoid metabolites). This involved longitudinal and point-in-time surveys of Salmonella shedding and environmental contamination on four commercial free-range laye...
متن کاملSalmonella serovar distribution and risk factors associated with persistence of shedding in finishing pigs
The objectives of this study were to describe the Salmonella serovar distribution and to identify risk factors associated with serovar persistence in finisher pigs. A longitudinal study was conducted in 18 cohorts of pigs. Fecal culture and serotyping were conducted using standard methods. Among the 446 Salmonella isolates (total 187 pigs), there were 18 distinct serovars. The six most common s...
