RONDON, Iang. BOVINE VIRAL DIARRHEA: PATHOGENESIS AND INMUNOPATHOLOGY. Rev.MVZ Cordoba [online]. 2006, vol.11, n.1, pp.694-704. ISSN 0122-0268.

Bovine viral diarrhea (BVD) represents a problem of worldwide causing considerable losses so much in meat livestock as in dairy herds, affecting it in diverse ways, which are subordinated to the age of the animal, immunologic state and moment of gestation, in which the infection takes place. BVD is caused by RNA virus, gender Pestivirus, family Flaviviridae, which has been classified in 2 biotypes (cytopathic and non cytopathic) according to its behavior in cultivation cells and in 2 genotypes (I and II) based on its genetic sequence. Depending on the infectious strains a square clinical matter is presented, varying in severity from a subclinic form, going by the clinical form and even producing the fatal disease of the mucous ones (MD) or causing deleterious effects on the fetus. Although studies already exist in our environment on this entity, the implementation of diagnostic methodologies constitutes an obstacle for the handling of the same one. This review is focused on pathogenyty and inmunopathology of the BVD.
