Transcriptome responses to Salmonella enterica serovar Reading in vaccinated and unvaccinated turkeys

Project description:The 2017-2019 foodborne outbreak of Salmonella enterica serovar Reading (S. Reading) in North America revealed the need for effective control of this serovar in turkey production. This study evaluated two live-attenuated Salmonella vaccines against an outbreak-associated strain of S. Reading in turkeys. At 1 day and 3 weeks of age, male turkey poults were either mock-vaccinated or given either an internally developed cross-protective vaccine and a commercially available vaccine. At 7 weeks of age, poults were challenged with S. Reading; one mock-vaccinated group was mock-challenged. Along with assessment of Salmonella colonization and dissemination, acute transcriptomic responses in the cecal tonsil were characterized at 2 days post inoculation and revealed decreased expression of genes encoding intestinal transporters and tight junction proteins. Vaccination with either vaccine mitigated most of the transcriptional changes in intestinal health-related genes induced by S. Reading in turkey cecal tonsil.

Transcriptional response of turkey blood leukocytes challenged with Salmonella enterica serovar Typhimurium UK1

Project description:Salmonella is one of most common causes of bacterial foodborne disease and consumption of contaminated poultry products, including turkey, is one route of exposure. Minimizing colonization of commercial turkeys with Salmonella could reduce the incidence of Salmonella-associated human foodborne illness. Understanding host responses to these bacteria could lead to potential strategies to minimize colonization and thus food safety risk. In this study, we evaluated bacterial load and blood leukocyte transcriptomic responses of 3-week-old turkeys challenged with the Salmonella enterica serovar Typhimurium (S. Typhimurium) UK1 strain. Turkeys (n = 8/dose) were inoculated with 108 or 1010 colony forming units (CFU) of S. Typhimurium UK1 and fecal shedding and tissue colonization were measured across multiple days post inoculation (dpi). Fecal shedding was 1-2 log10 higher in the 1010 CFU group than the 108 CFU group, but both doses effectively colonized the crop, spleen, ileum, cecum, colon, bursa of Fabricius and cloaca without causing any overt clinical signs in either group of birds. Blood leukocytes were isolated from a subset of the birds (n =3-4/dpi) both pre-infection (0 dpi) and 2 dpi with 1010 CFU and their transcriptomic responses assayed by RNA-sequencing (RNA-seq). After 2 dpi, 647 genes had significant differential expression (DE), including large increases in expression of immune genes such as CCAH221, IL4I1, LYZ, IL13RA2, IL22RA2, and ACOD1. IL1B was predicted as a major regulator of DE in these leukocytes and this DE was predicted to activate cell migration, phagocytosis and proliferation, and to impact the STAT3 and toll-like receptor pathways. These data revealed genes and pathways by which turkey blood leukocytes responded to the pathogen and can provide potential targets for developing intervention strategies or diagnostic assays to mitigate S. Typhimurium in turkeys.

Expression analysis of Salmonella enterica serovar Typhimurium UK1 delta-iacP mutant

Project description:Investigation of whole genome gene expression level changes in a Salmonella enterica serovar Typhimurium UK1 delta-iacP mutant, compared to the wild-type strain. IacP is resoponsible for the secretion of virulence effector proteins via the type III secretion system, thereby contributing the virulence of S. Typhimurium. The mutants analyzed in this study are further described in Kim et al. 2011. Role of Salmonella Pathogenicity Island 1 Protein IacP in Salmonella enterica Serovar Typhimurium Pathogenesis. Infection and Immunity 79(4):1440-1450 (PMID 21263021). A chip study using total RNA recovered from two separate wild-type cultures of Salmonella enterica serovar Typhimurium UK1 and two separate cultures of a mutant strain, Salmonella enterica serovar Typhimurium UK1 delta-iacP. Each chip measures the expression level of 4,302 genes from Salmonella enterica serovar Typhimurium.
