                                    Citation: N/AInterpretive Summary:
                                Technical Abstract: Chickens were immunized subcutaneously with an Eimeria recombinant profilin protein plus MontanideTM ISA 70 VG (ISA 70) or MontanideTM ISA 71 VG (ISA 71) water-in-oil adjuvants, or with profilin alone, and comparative RNA microarray analyses were performed to ascertain global transcriptomic changes induced by profilin/ISA 70 vs. profilin alone and by profilin/ISA 71 vs. profilin alone. Immunization with profilin/ISA 70 vs. profilin alone altered a greater number of transcripts compared with profilin/ISA 71 vs. profilin alone (509 vs. 296). Furthermore, alterations in transcript expression was evident for 10 canonical pathways in the profilin/ISA71 vs. profilin alone analysis compared to only two pathways for the profilin/ISA 70 vs. profilin alone analysis. Based on this analyses, ISA 71 was selected as a candidate adjuvant in conjunction with profilin vaccination for in vivo disease protection studies. Vaccination with profilin/ISA 71 was associated with greater body weight gain following E. acervulina infection, and decreased parasite fecal shedding after E. maxima infection, compared with profilin alone. Anti-profilin antibody levels were higher in sera of E. maxima- and E. tenella-infected chickens vaccinated with profilin/ISA 71 compared with profilin alone. Finally, the levels of transcripts encoding interferon-c, interleukin (IL)-2, IL-10, and IL-17A were increased in intestinal lymphocytes from E. acervulina-, E. maxima-, and/or E. tenella-infected chickens vaccinated with profilin/ISA 71 compared with profilin alone. None of these effects were seen in chickens injected with ISA 71 alone indicating that the adjuvant was not conferring non-specific immune stimulation. These results suggest that profilin plus ISA 71 augments protective immunity against specific Eimeria species in broiler chickens.
