Abstract

ABSTRACT At the Animal Sanitation Lab of the Holstein Friesian Association of Ecuador, located in the Conocoto Canton, Pichincha Province, the incidence and prevalence of the bovine brucellosis was evaluated analyzing blood samples obtained from animals belonging to different dairy herds of the Carchi, Imbabura and Pichincha provinces. For this a stratified sampling was applied during 120 days of investigation. In 2009 the different percentages of Brucella abortus infection were presented recording the highest percentage in the bovines belonging to the Carchi province with 8.52% incidence, 0.75% in the bovines from Imbabura and 0.6% in the bovines belonging to Pichincha, while in general in Northern Sierra region this disease is disseminated in 1.80% of the existing bovines. It was determined that the prevalence of Brucella abortus, in Carchi province the prevalence tends to increase during the 2006-2009 period recording an increase of the incidence of 3.11% in the year 2006 to 8.52%; on the other hand, the losses caused by the bovine infection with Brucella abortus per cow and per farm reach 493.70 and 1104.19 US, this is why it recommended to spread to obtained results at the level of the corresponding animal and human health entities to faithfully apply policies for the control and prevention of this zoonosis disease based on the AGROCALIDAD policies
