Immune protection in animals: the examples of rinderpest and foot-and-mouth disease.

Expression in cattle of epitopes of a heterologous virus using a recombinant rinderpest virus.

We have investigated the bovine immune response to heterologous proteins expressed using a recombinant rinderpest virus (RPV). A new gene unit was created in a cDNA copy of the genome of the vaccine strain of RPV, and an open reading frame inserted that encodes the polymerase (3Dpol) and parts of the capsid protein VP1 from foot-and-mouth disease virus (FMDV). Infectious recombinant RPV was res...

CpG-DNA enhancement the immune elicited as adjuvant of foot- and- mouth disease vaccine

In the present study the effect of the locally produced genetic adjuvant of ginea pig specific CpG-motif-containing oligodeoxynucleotide (CpG-ODN) in an inactivated FMD virus vaccine was evaluated. Boosting the ginea pigs with FMD vaccine along with CpG-ODN adjuvant produced relatively higher ratio (5-fold) of FMDV-specific IgG2a / IgG1 than those vaccinated in the absence of CpG-ODN. The neutr...

Developing Vaccines against Foot-and-Mouth Disease: a Biotechnological Approach

Foot-and-mouth disease (FMD) is a contagious viral disease of livestock with significant economic effect. It is prevalent in various regions of Asia, Africa, and South America. The causative agent of this disease is called foot-and-mouth disease virus (FMDV), which is a member of Aphthovirus genus. Vaccination is an effective technique to prevent the complications of FMD and to eradicate the di...
