The aim of this study was to determine whether SNP at position -824 (promoter region) of the TNFα gene significantly differentiates the size of IgM+, CD5+ and CD11b+ cell subpopulations and affects the expression of membrane-bound TNFα protein (mTNFα) on these cells and their susceptibility to BLV infections. In this study, significant differences were determined for the first time between TNFα genotypes and the percentage of cells with the CD11b+TNFα+p24+ immunophenotype. Furthermore, greater expansion of lymphocytes with the IgM+TNFα+p24+ immunophenotype was reported in cows with the G/G genotype than in A/A homozygotes. Cells with the above immunophenotype were more frequently observed in cows with persistent leukocytosis than in aleukemic cattle. Our results suggest that polymorphism of the TNFα -824 A>G gene and mTNFα protein expression play an important role in the pathogenesis of enzootic bovine leukosis.

The objective of this study was to verify the hypothesis that increasing levels of dietary methionine can stimulate the mechanisms of cell-mediated and humoral immunity in young turkeys. The blood and organs involved in cell-mediated and humoral immune responses were analyzed in 8-week-old turkeys that had been vaccinated against Ornithobacterium rhinotraheale (ORT) infection (on days 17 and 48). The birds were fed diets with a low (LM), medium (MM) and high (HM) methionine content (0.45 and 0.40%, 0.60 and 0.51%, 0.71 and 0.57% in weeks 1 – 4 and 5 – 8, respectively). Dietary methionine supplementation led to a significant increase in body weights of turkeys at 56 days of age, from 3532 g in group LM to 3720 g in group MM and 3760 g in group HM (p=0.001). A significant increase in vaccine-induced antibody titers against ORT was noted in group HM relative to group LM (p=0.006). Increasing levels of methionine had no significant effect on total serum IgG nor IgM levels and most serum biochemical parameters, TP, ALB, GLOB, GLU, AST, ALP, P and Ca. In comparison with group LM, group HM turkeys were characterized by a lower percentage of IgM⁺ B cell subpopulation in the blood and bursa of Fabricius. The percentages of CD4⁺ and CD8⁺ T cell subpopulations in the bursa of Fabricius in group HM were significantly different from those found in groups LM and MM. The highest percentages of CD4⁺ T cells and CD8⁺ T cells in the spleen were observed in groups LM (p<0.001) and HM (p=0.04), respectively. The differences were statistically significant relative to the remaining groups. Turkeys of group LM were characterized by a lower CD4⁺ T cell percentage in the thymus (p<0.001) and a lower CD8⁺ T cell percentage in the cecal tonsils (Cts) (p<0.01). Vaccination against ORT resulted in a significant increase in the percentage of CD4⁺/CD8⁺ T cell subpopulation and a decrease in the percentage of CD8⁺ T cell subset in the spleen.

The objective of this study was to determine the effect of different levels of dietary methionine on selected immune parameters of young turkeys. A total of 357 one-day-old female Hybrid Converter turkeys were randomly divided into three groups with low, medium and high level of dietary methionine (LM, MM, HM) of seven replicates each. Methionine was added to the basal diet (LM) at 0.16% (MM) and 0.32% (HM). At 17 days of age, seven birds per group were vaccinated against Ornithobacterium rhinotraheale (ORT) infection, with ORNITIN (ABIC) vaccine. At 28 days of age, blood was sampled and the birds were euthanized. The serum concentrations and activity of selected biochemical parameters, total IgY and IgM, and vaccine-induced antibody titers (IgY) against ORT were determined. The percentages of CD4⁺, CD8⁺, CD4⁺/CD8⁺ T cell subpopulations and IgM⁺ B cell subpopulation were determined in blood and organs by flow cytometry. Different supplementary levels of methionine had no significant effect on vaccine-induced antibody titers against ORT or total serum IgM and IgY levels, as well as on the percentages of peripheral blood T and B cell subsets. Increasing dietary methionine rates decreased the percentage of CD4⁺ T cell subpopulation, however it has increased the percentage of IgM⁺ B cell subpopulation in the spleen. Vaccination against ORT resulted in a significant decrease in the percentage of CD4⁺ T cell subset and an increase in the percentage of CD8⁺ T cell subset in the spleen. It could be concluded that MM turkeys have developed the most desirable values of immune parameters.

The study was conducted on 672 one-day-old female Hybrid Converter turkeys divided into 6 dietary treatments (7 replications per group) which differed in DL-methionine (DL-Met) supplementation levels. The Met content in diets between 1 – 4/5 – 8 weeks of feeding was as follows: 4.1/3.7, 4.7/4.1, 5.6/4.6, 6.1/5.0, 6.8/6.5 and 7.5/7.4 g · kg-1. In groups 3 and 5, dietary Met levels corresponded to those recommended by NRC (1994) and B.U.T. (2012), respectively. The lowest Met content of the diet, without supplemental pure Met, caused a significant decrease in the bird body weight gains. In comparison with group 1, a considerable increase in dietary Met concentrations led to a decrease in the plasma levels of urea ( = 0.042), total protein and albumin ( < 0.001) in groups 4 – 6, and in the activity of γ-glutamyl transferase in all other groups ( < 0.001). The highest glutathione peroxidase (activity and the lowest lipid peroxide concentration in the turkeys’ blood were noted in treatments 4 and 5. The lowest and the highest Met content significantly decreased ferric reducing ability of plasma values ( < 0.001 vs the other groups). Plasma immunoglobulin A concentrations were significantly ( < 0.001) higher in groups 1 and 3 than in the remaining groups. In conclusion, the diet without Met supplementation compromised the growth performance and antioxidant status of turkeys. Diets supplemented with Met according to B.U.T. (2012) recommendations or at levels slightly lower exerted the strongest antioxidant effect.
