Effects of two direct-fed microbials on the ability of pigs to resist an infection with <b><i>Salmonella enterica</i></b> serovar Typhimurium
نویسندگان
چکیده
Materials and methods: Forty finishing pigs were used in a 12-day disease challenge study. Dietary treatments included no DFM (Control; 20 pigs), DFM provided in drinking water (E faecium), or DFM provided in feed (Bacillus). Ten Control pigs were not challenged with Salmonella Typhimurium; the remaining 30 pigs were inoculated on Day 0. Fecal samples were cultured for Salmonella Typhimurium on Days 0 to 5, 9, and 12. Serum haptoglobin (Hp), α1-acid glycoprotein (AGP), IgG, and IgM concentrations were measured. Pigs were euthanized on Day 12, and tissue and digesta were tested for presence and numbers of salmonellae.

Oral inoculation with Salmonella enterica serovar Typhimurium or Choleraesuis promotes divergent responses in the somatotropic growth axis of swine.
Enteric disease and immune challenge are processes that have detrimental effects on the growth performance of young swine. The current study tested the hypothesis that salmonella-induced enteric disease would perturb the endocrine growth axis in a serovar-dependent fashion. Specifically, we evaluated the effects of Salmonella enterica serovar Typhimurium (Typhimurium) and serovar Choleraesuis (...
متن کاملSalmonella enterica serovar typhimurium-induced maturation of bone marrow-derived dendritic cells.
Murine bone marrow-derived dendritic cells (DC) can phagocytose and process Salmonella enterica serovar Typhimurium for peptide presentation on major histocompatibility complex class I (MHC-I) and MHC-II molecules. To investigate if a serovar Typhimurium encounter with DC induces maturation and downregulates their ability to present antigens from subsequently encountered bacteria, DC were pulse...

Salmonella enterica subsp. enterica serovar 4,[5],12:i:- is a monophasic variant of S. enterica serovar Typhimurium (antigenic formula 4,[5],12:i:1,2). Worldwide, especially in several European countries and the United States, it has been reported among the 10 most frequently isolated serovars in pigs and humans. In the study reported here, 148 strains of the monophasic serovar isolated from pi...
