Responses to the parenteral administration of a live aroA deletion Salmonella serovar Typhimurium vaccine given to three brown egg layer strains and two broiler strains were studied. Twenty-five birds of each strain were reared together in floor pens to 6 weeks of age and then moved as individual strains to new floor pens and injected with 10(8) colony forming units (CFU) per bird of the vaccin...
Background and Aims: Infectious bursal disease (IBD) is an acute contagious viral disease of birds worldwide. The causative virus induces a persistent immune suppression following destroy B lymphocytes precursors in bursal lymphoid follicles.

The Bacille Calmette Guerin (BCG) vaccine can provide decades of protection against tuberculosis (TB) disease, and although imperfect, BCG is proof that vaccine mediated protection against TB is a possibility. A new TB vaccine is, therefore, an inevitability; the question is how long will it take us to get there? We have made substantial progress in the development of vaccine platforms, in the ...
Background & Aims : In this study the efficacy of the mixture of ICI118,551 and alum, as an adjuvant, in the induction of humoral and cellular immunity response to heat-killed Salmonella typhimurium (S. typhimurium) (HKST) as a model vaccine was investigated. Materials and Methods : BALB/c mice were divided into five groups. Mice in the experimental groups received either the HKST vaccine...
A phase I clinical vaccine study of a human immunodeficiency virus type 1 (HIV-1) vaccine regimen comprising a DNA prime formulation (5-valent env and monovalent gag) followed by a 5-valent Env protein boost for seronegative adults was previously shown to induce HIV-1-specific T cells and anti-Env antibodies capable of neutralizing cross-clade viral isolates. In light of these initial findings,...
