Metabolic parameters linked by phenotype microarray to acid resistance profiles of poultry-associated Salmonella enterica.

Phenotype microarrays were analyzed for 51 datasets derived from Salmonella enterica. The top 4 serotypes associated with poultry products and one associated with turkey, respectively Typhimurium, Enteritidis, Heidelberg, Infantis and Senftenberg, were represented. Datasets were partitioned initially into two clusters based on ranking by values at pH 4.

Reduction of Salmonella Enteritidis in the spleens of hens by bacterins that vary in fimbrial protein SefD.

The objective of this research was to determine whether variation in the presence of fimbrial protein SefD would impact efficacy of bacterins as measured by recovery of Salmonella enterica serovar Enteritidis (Salmonella Enteritidis) from the spleens of hens. Two bacterins were prepared that varied in SefD content. Also, two adjuvants were tested, namely, water-in-oil and aluminum hydroxide gel (alum).

Recovery of Salmonella enterica serovar Enteritidis from hens initially infected with serovar Kentucky.

Salmonella enterica serovars Enteritidis and Kentucky differ greatly in epidemiology. We wanted to know if the non-pathogenic serotype Kentucky impacted the recovery of the pathogen Enteritidis from chickens. To explore this issue, 4 groups of hens were treated as follows: (i) hens were inoculated orally with Kentucky and injected intramuscularly 2 weeks later with Enteritidis, (ii) hens were contact infected with Kentucky and then with Enteritidis, (iii) hens were injected with Enteritidis only, and (iv) hens were contact infected with Enteritidis only.

Presence of Salmonella enteritidis and Salmonella gallinarum in commercial laying hens diagnosed with fowl typhoid disease in Colombia.

A severe outbreak of salmonellosis in commercial brown table egg layers first occurred in Colombia in 2006. From 2008 to 2012, 35 samples collected from commercial layers farms in the states of Cundinamarca, Santander, Bolivar, and San Andres, were positive for Salmonella enterica. Salmonella was isolated from liver and spleen (71.

Serotype and antimicrobial resistance patterns of Salmonella isolates from commercial birds and poultry environment in Mississippi.

To obtain information about Salmonella from commercial birds and poultry environments within Mississippi, 50 Salmonella enterica isolates were collected and characterized by intergenic sequence ribotyping (ISR) serotyping and by determining antimicrobial resistance. ISR assigned serotype to all 50 Salmonella enterica isolates whereas the Kauffman-White-LeMinor antibody-based scheme assigned serotype to 48. Agreement between both methods was K = 89.
