Control of bovine viral diarrhea (BVDV): a study focusing on patent documents

Abstract

The virus of bovine viral diarrhea ( BVDV ) is considered, worldwide, one of the most important pathogens for cattle herds, and despite wide dissemination in Brazil, observational studies that estimate the prevalence and risk factors associated with BVDV in the country still they are scarce. The co ntrol of BVDV infection based on identification and removal of persistently infected herd animals, in addition to vaccination of susceptible animals to prevent clinical form, reproductive losses and production of infected animals. Vaccination is therefore widely applied to control these viruses. Thus, this study aimed to verify the technological patents relating to vaccines that are being develop under the control of BVDV, for study patentmetrics . Verification of the global landscape of patent documents rel ated to technology of vaccines paying attention to requests for deposits arranged in the databases of the National Institute of Intellectual Property in Brazil and based European Patent Office ( ESPACENET ). It was found that the research related to BVDV is held uninterruptedly for everyone. The dynamism of the disease causes more, more vaccines that are new are developed, and recently, researchers from every continent are conducting research with BVDV.
