In this context, the PCR Kit for Bovine Viral Diarrhea Virus (BVDV) Detection constitutes a precise tool for BVDV diagnosis, promoting health for your herd.
Bovine Viral Diarrhea (BVD) is an infectious disease of great relevance to worldwide cattle farming, caused by the Bovine Viral Diarrhea Virus (BVDV), belonging to the genus Pestivirus, family Flaviviridae. The disease has wide geographical distribution and is associated with significant economic losses, mainly due to reproductive damage, immunosuppression, and reduced productive performance of herds.
Etiologic Agent
BVDV is a single-stranded RNA virus with a lipid envelope, classified into two main genotypes (BVDV-1 and BVDV-2), both capable of causing clinical and subclinical infections. The virus also presents two biotypes, cytopathic and non-cytopathic, defined by the effect caused in cell cultures.
Epidemiology
Bovine Viral Diarrhea is widely disseminated in cattle herds, being transmitted primarily through direct contact between animals, body secretions, fetal fluids, semen, and contaminated materials. Persistently infected (PI) animals represent the main source of infection, continuously shedding the virus throughout their entire lives.
Clinical Manifestations
The clinical manifestations of BVD are varied and depend on the age, immunological status, and gestational stage of the animal. They may include diarrhea, fever, apathy, mucosal lesions, immunosuppression, abortions, congenital malformations, stillbirths, and reduced fertility. In more severe cases, Mucosal Disease may occur, which is usually fatal.
Diagnosis
The diagnosis of Bovine Viral Diarrhea is based on the association of clinical data, reproductive history, and laboratory tests. Serological tests are used for antibody detection and molecular methods, such as RT-PCR, for direct virus identification, especially in the detection of persistently infected animals.
Prevention and Control
BVDV control requires the implementation of integrated health programs, including biosecurity measures, animal movement control, quarantine of introduced animals, and proper management of pregnant females. Vaccination is an important tool, and should be used strategically and associated with the identification and elimination of persistently infected animals.
Health and Economic Importance
Bovine Viral Diarrhea causes significant impacts on the productivity and profitability of bovine production systems. In addition to direct losses related to mortality and performance decline, the disease compromises reproductive efficiency and increases costs with treatments and sanitary control measures.
