The present study was conducted to compare aqueous nanoparticle-based Montanide™ IMS 1313 N VG PR (IMS 1313) and oil-based ISA 71 VG (ISA71) adjuvants in combination with an Eimeria subunit protein vaccine on protection against avian coccidiosis. Male broiler chicks were vaccinated twice with an Eimeria recombinant profilin protein alone or in conjunction with IMS 1313 or ISA 71 prior to infection with live, sporulated Eimeria acervulina oocysts. For comparison, chickens were immunized with a commercial live coccidiosis vaccine (Coccivac-B). The following parameters were assessed as measures of protective immunity: body weight gain, fecal oocyst output, profilin-specific intestinal secretary IgA (sIgA) or IgY antibody levels, and percentages of CD4(+), CD8(+), TCR1(+), or TCR2(+) intestinal intraepithelial lymphocytes (IELs). Birds vaccinated with profilin plus ISA 71 had increased body weight gains, equivalent to Coccivac-B vaccination, compared with the profilin-only group. Immunization with profilin plus IMS 1313, or with profilin plus ISA 71, reduced fecal oocysts shedding compared with the profilin-only group. Intestinal sIgA levels were greater in the profilin plus IMS 1313 or ISA 71 groups, and IgY levels were greater in the profilin plus ISA 71 group, compared with profilin alone. Birds vaccinated with profilin plus IMS 1313 or ISA 71 had higher percentages of CD4(+), CD8(+), and TCR1(+), but not TCR2(+), intestinal IELs compared with the profilin-only vaccinated group. Taken together, these results indicate that immunization of chickens with the recombinant profilin subunit vaccine in conjunction with IMS 1313 or ISA 71 adjuvants increases protective immunity against experimental E. acervulina infection.

D007071 Immunoglobulin A, Secretory The principle immunoglobulin in exocrine secretions such as milk, respiratory and intestinal mucin, saliva and tears. The complete molecule (around 400 kD) is composed of two four-chain units of IMMUNOGLOBULIN A, one SECRETORY COMPONENT and one J chain (IMMUNOGLOBULIN J-CHAINS).

D007114 Immunization Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).

D007136 Immunoglobulins Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

D008353 Mannitol A diuretic and renal diagnostic aid related to sorbitol. It has little significant energy value as it is largely eliminated from the body before any metabolism can take place. It can be used to treat oliguria associated with kidney failure or other manifestations of inadequate renal function and has been used for determination of glomerular filtration rate. Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity. (L)-Mannitol,Osmitrol,Osmofundin

D011948 Receptors, Antigen, T-Cell Molecules on the surface of T-lymphocytes that recognize and combine with antigens. The receptors are non-covalently associated with a complex of several polypeptides collectively called CD3 antigens (CD3 COMPLEX). Recognition of foreign antigen and the major histocompatibility complex is accomplished by a single heterodimeric antigen-receptor structure, composed of either alpha-beta (RECEPTORS, ANTIGEN, T-CELL, ALPHA-BETA) or gamma-delta (RECEPTORS, ANTIGEN, T-CELL, GAMMA-DELTA) chains.
