Quarantine or physical separation of replacement cattle from the resident herd for 2—4 weeks should be considered, and vaccination of replacement cattle for BVD should be done before commingling with the resident herd.
Embryo donors and recipients also should be tested for persistent infection. If vaccination of embryo donors or recipients is warranted, it should be done at least one estrous cycle before embryo transfer is performed. Because BVDV is shed into semen, breeding bulls should be tested for persistent infection before use. Artificial insemination should be done only with semen obtained from bulls free of persistent infection. Screening cattle herds for persistent infection can be done by PCR assays using blood or milk; by classical virus isolation methods using serum or buffy coat cells; by antigen-capture ELISA using serum, buffy coat, milk, or skin biopsies; or by antigen detection using immunochemical methods on tissue or skin biopsies.
Several strategies, based on herd size, type of herd being screened, financial limitations of the herd owner, and testing ability of the diagnostic laboratory being used, are available to screen herds for persistent infection. When identified, persistently infected cattle should be removed from the herd as soon as possible, and direct or indirect contact with pregnant cattle should be prevented.
Inactivated and modified-live virus vaccines are available. They contain a variety of strains of BVDV representing both viral biotypes and viral genotypes 1 and 2. Antigenic diversity among BVDV may affect the efficacy of a given vaccine if the vaccine virus or viruses differ significantly from the challenge virus. Because BVDV is fetotropic and immunosuppressive, use of modified-live virus vaccines is not recommended in cattle that are pregnant or showing signs of disease.
Inactivated viral vaccines may be used in pregnant cattle. Protection conferred by inactivated vaccines may be of short duration, and frequent vaccination may be necessary to prevent disease or reproductive failure. Colostral antibody confers partial to complete protection against disease in most calves for 3—6 months after birth.
Vaccination of neonatal cattle that have acquired colostral antibody may not stimulate a protective immune response, and revaccination at 5—9 months of age may be necessary. A booster dose of vaccine is often administered before first breeding, and additional booster doses of vaccine may be administered in subsequent years before breeding. Signs of bovine viral diarrhea can range from inapparent infection to severe enteritis, abortion, and death.
Mucosal disease is a form of infection that occurs in persistently infected cattle and is typically fatal. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world.

Anthrax is a zoonotic disease affecting a broad range of species. Naturally occurring infections can cause illnesses that range from an acute, highly fatal form to a less acute and less serious clinical illness that can also be fatal. Which of the following species is most likely to develop acute fatal disease with anthrax infection?
