Abstract
Brucellosis is a disease with implications in the public health due both to its zoonotic character as its easy transmission trough of dairy products contaminated with the microorganism Brucella sp. The aim of this article was determinate the prevalence of bovine brucellosis in nine municipalities that carrying the 75% of bovine population in the Caquetá state, Colombia. Blood samples were collected in 100 herds dedicates to dual-purpose cattle, obtained blood serum from 1000 animals, of which 882 corresponding to cows. Rose Bengal Plate Test was performed and the confirmations of positive cases were made by competitive Elisa. The sero-prevalence of bovine brucellosis in Caquetá state was of 3.23% (95%, CI: 0-6.53%), in males 2.6% and females 3.29% respectively. At the municipal level, the sero-prevalence varied of 0 to 6.06%. The prevalence of brucellosis at herd level was of 22% (95%, CI: 12.24-31.76%). In conclusion, the sero-prevalence is low in bovines but moderate at the level of herds, therefore, it is necessary to increase the performance of the official control entities at the level of herds to reduce the high prevalence of the disease for guaranteed the safety of milk and thus the health of consumers.

Brucellosis is a highly contagious bacterial infection of livestock and continues to be of great health concern and economic importance in worldwide (Maadi, Moharamnejad, & Haghi, 2011); (Pathak et al, 2016). This disease is caused by aerobic gram-negative bacteria of the genus Brucella, which affect domestic animals, wild animals and human, being an important public health problem in many parts of world (Aguirre et al, 2008; Reyes, Sánchez, Lotero, Restrepo, & Palacio, 2010; Akbarmehr & Ghiyamirad, 2011), and the brucellosis is considering a re-emerging zoonosis (Seleem, Boyle, & Sriranganathan, 2009)
Until the year 2013, 32 municipalities were certificated free of bovine brucellosis, none from the Caquetá state (FEDEGAN, 2013)

The objective of this research was determinate the prevalence of bovine brucellosis in the nine municipalities that produce 90% of milk in the Caquetá state
