The role of Salmonella Genomic Island 4 in metal tolerance of Salmonella enterica serovar I 4,[5],12:i:- pork outbreak isolate USDA15WA-1

Project description:Multidrug-resistant (MDR; resistance to >3 antimicrobial classes) Salmonella enterica serovar I 4,[5],12:i:- strains were linked to a 2015 foodborne outbreak from pork. Strain USDA15WA-1, associated with the outbreak, harbors an MDR module and the metal tolerance element Salmonella Genomic Island 4 (SGI-4). Characterization of SGI-4 revealed that conjugational transfer of SGI-4 resulted in the mobile genetic element (MGE) replicating as a plasmid or integrating into the chromosome. Tolerance to copper, arsenic, and antimony compounds was increased in Salmonella strains containing SGI-4 compared to strains lacking the MGE. Following Salmonella exposure to copper, RNA-seq transcriptional analysis demonstrated significant differential expression of diverse genes and pathways, including induction of numerous metal tolerance genes (copper, arsenic, silver, and mercury). Evaluation of swine administered elevated concentrations of zinc oxide (2,000 mg/kg) and copper sulfate (200 mg/kg) as an antimicrobial feed additive (Zn+Cu) in their diet for 4 weeks prior to and 3 weeks post-inoculation with serovar I 4,[5],12:i:- indicated that Salmonella shedding levels declined at a slower rate in pigs receiving in-feed Zn+Cu compared to control pigs (no Zn+Cu). The presence of metal tolerance genes in MDR Salmonella serovar I 4,[5],12:i:- may provide benefits for environmental survival or swine colonization in metal-containing settings.

Neonatal and maternal dietary interventions in piglets

Project description:Feed additives aiming to improve gastrointestinal health are frequently supplied to piglets after weaning but might be more effective when administered before weaning. In this period, feed additives can either be administered directly to neonates, or indirectly via sow’s feed. It is yet unknown what the effect of the administration route is on gut functionality and health. Therefore, we compared the effect of different dietary interventions on gut functionality after maternal administration (lactation feed) to the neonatal administration route (oral gavage). These feed interventions included medium chain fatty acids (MCFA), beta-glucans (BG), and galacto-oligosaccharides (GOS). We measured intestinal gene expression and microbiota composition after birth (d1) and after weaning (d31). Our results show that the type of intervention and the administration route influence gut functionality (microbiome and gene expression profiles). MCFA administration led to a more differentially orchestrated response when comparing the neonatal and maternal administration route then the other two additives, indicating the route of administration of the feed interventions is determinative for the outcome. This implies that for each nutritional intervention in early life of a pig the optimal route of administration needs to be determined.
