Definitions

  • This invention relates to the field of Bovine Viral Diarrhea Virus (BVDV), and vaccines for the treatment thereof.
  • Bovine viral diarrhea virus is a Pestivirus belonging to the family of the Flaviviridae. It causes a number of different conditions in sheep, goats, and especially cattle. The symptoms depend upon the age, physiological and virological state of the animal. In young susceptible calves and young adults it causes a disease which is characterized by high morbidity and low mortality. The symptoms can include fever, depression, occulo-nasal discharges, diarrhea and occasionally oral ulcerations. Apart from these primary effects the virus also causes immunosuppression. Although primary BVDV infections are normally relatively mild, the virus may potentiate or enhance the pathogenicity of other co-infecting microorganisms.
  • BVDV causes similar symptoms to those described above for younger susceptible calves.
  • the virus in pregnant a * n * i ⁇ nalp the virus has the ability to cross the placenta and infect the fetus. The outcome of this infection depends upon the age of the fetus and whether it is at a stage where its immune system is fully competent.
  • the possible outcome of infections include fetal reabsorption, abortion, mummification, congenital defects, birth defects, calves born which are persistently infected with BVDV and completely normal calves. Calves born which are persistently infected with BVDV, represent the most important segment of this BVDV pathogenesis complex.
  • Persistently infected animals shed large amounts of virus into their environment which can infect susceptible animals. Furthermore, even though persistently infected animals are immunotolerant to the virus which infected them in utero, they do develop disease when infected with other closely related BVDV biotypes. These infections are characterized by low morbidity (because relatively speaking there will not be many pregnant animals infected at the right time during pregnancy to produce BVDV persistently infected normal calves), but high mortality. This disease syndrome is known as mucosal disease and often manifests itself as a peracute condition with calves dying of a profuse watery diarrhea which contains large amounts of fresh blood.
  • inactivated vaccine preparations are not as effective as attenuated live vaccines.
  • Inactivated antigen from inactivated vaccine preparation undergoes exogenous processing. After injection into the animal the antigen becomes part of the animal's soluble protein mileau. The antigen enters antigen presenting cells through pinocytotic mechanisms and this usually produces antibodies.
  • Antigen from live virus which replicates inside cells undergoes endogenous processing and this mechanism produces the preferred cell mediated immune responses.
  • Cell mediated immune responses can recognize cells infected with viruses and have the potential of interrupting the virus life cycle at a much earlier stage. Cell mediated responses are thus thought to be extremely important in the immunological defense to many viral infections.
  • An animal owner may be vaccinating animals to protect against a disease but because of the properties of the vaccine the owner provides an opportunity for other diseases to afflict the animals. This forces the owner to use inactivated BVDV vaccines, which because of the way in which the immune system operates, are not particularly effective.
  • inactivated vaccines are safe but not particularly effective while the attenuated live vaccines are more effective but under certain conditions may not be very safe.
  • Bovine herpesvirus type l (BHV-l) is another major pathogen of cattle which produces respiratory disease.

  • Preclude would suggest the onset of the disease state either does not occur or the disease pathogen is largely ineffectual in causing the disease state.
  • Prevent or prevention can indicate the disease state is forstalled, meaning that anticipatory action to prevent or hinder the disease has occurred but the conditions creating the disease have not been eliminated.
  • Another object of the invention is to provide a BVDV vaccine which can be administered safely to calves and to pregnant cows in all stages of pregnancy.

  • the vaccines of this invention contain genes that express large quantities of gp53, this is shown in figure 5. Because of the expression of large quantities of gp53 the vaccines of this invention will confer substantial benefits upon the treated potential host.
  • Preferred Compounds - Any BHV-1 virus attenuated with a tk deletion and carrying the gp53 gene, the gp53 gene being preceded by a signal peptide, that expresses abundant amounts of gp53, should be a preferred suitable vaccine candidate. It appears the signal peptide sequence may be taken from any suitable source. We chose to examine two different signal peptides to ensure the best localization of the gp53 protein in vivo. We chose two candidates we call “Tll-6", embodied in Example 2, and “Tll-3", embodied in Example 3 for vaccine trials. The former virus was deposited to the ATCC under the designation UC VR-58. The latter, "Tll-3" plasmid was also deposited.
