Immune responses in bovines to recombinant glycoprotein D of bovine herpesvirus type 5 as vaccine antigen.

Bovine herpesvirus 5 (BoHV-5) is responsible for outbreaks of meningoencephalitis that cause important economic losses in young cattle. BoHV-5 glycoprotein D (gD5) is essential for attachment and penetration into permissive cells and targeting of host immune systems, inducing strong humoral and cellular immune responses. The aim of this study was to evaluate the vaccinal immune response of vaccines formulated with the recombinant BoHV-5 gD (rgD5) in bovines.

Production, purification and therapeutic potential of egg yolk antibodies for treating Trypanosoma evansi infection.

The use of avian antibodies has aroused interest in biomedical research due to the numerous advantages compared to mammal's antibodies. Our study aimed to produce and purify IgY immunoglobulins in order to use as an alternative therapy against Trypanosoma evansi. Every 14 days, four New Hampshire chickens were immunized with trypomastigotes of T.

Immune responses of mice against recombinant bovine herpesvirus 5 glycoprotein D.

Glycoprotein D (gD) is essential for attachment and penetration of Bovine herpesvirus 5 (BoHV-5) into permissive cells, and is a major target of the host immune system, inducing strong humoral and cellular immune responses. The aim of this study was to evaluate in mice the immunogenicity of recombinant BoHV-5 gD (rgD5) expressed in Pichia pastoris. Vaccines formulated with rgD5 alone or adjuvanted with Montanide 50 ISA V2; Emulsigen or Emulsigen-DDA was administered intramuscularly or subcutaneously.
