INTRODUÇÃO:

The bovine brucellosis is a endemic and chronic infectious disease, caused by a bacterium of the gender Brucella sp (Del Fava et al., 2003). It is one of the most spread zoonosis in the world, and tends in abortion the main significant clinical sign. The fall on the meat and milk production is also a concern on the livestock chain production (Acha & Szyfres, 2001; Sola, 2011). Among the alive vaccines used, the B19 vaccine was and it still continues being used broadly in control programs on several countries (Jones & Hooper, 1976). Serological tests based on the reaction among antigens of Brucella sp., and antibodies are the most reliable tool to identify infected animals. (Poester et al., 2005; Lage et al., 2008).

OBJETIVO DO TRABALHO:

To identify the frequency of vaccinated animals to bovine tuberculosis in the Acre State. For this purpose was held a retrospective study using official data from 2007 to 2011. Additionally a survey to detect the frequency of infected animals were held to evaluate the epidemiologic situation of the disease on the State.

MÉTODOS:

Maps with dada on bovine brucellosis vaccination were analyzed. The dada was donated by the Animal Sanitary Defense Institute of the State of Acre (IDAF) and State Coordination of the State Program. The data concerns the female bovine animals with age among the and eight months of age, with no distinction of breed, existent in the Acre, from 2007 to 2011. Those data were routed to the Institute and Coordination to the of Agriculture Federal Superintendence - AFS/AC, in the period from 2007 to 2011. The reports contained data on the exams of bovine brucellosis, using the Acidified Antigen Buffered (AAB), done by qualified veterinarians doctors. The reports were sent monthly to the State Coordination of PNCEBT, in IDAF-AC and then directed to AFS/AC. The statistical analysis was based on the descriptive statistics, using the frequency analysis, the average and standard deviation, through the Excel, Windows 2006.

RESULTADOS E DISCUSSÃO:

In the period from 2007 to 2011, the number of rural properties in the State of Acre, stayed practically stable. A small growth was observed in the year of 2008. The number of properties with vaccination began to decrease starting from 2008. Additionally was observed that the percentile of properties with vaccination decreased, during 2011, the worst result (1.79%). In that period, the number of existent properties stayed practically stable. Was observed a decrease on the number of municipal districts focus, from 15 to eight districts focus. The number of attended properties suffered a flotation during the period in study, varying from 395 (2007) to 123 (2007). The number of properties focus decreased, from 155 (2007) to 16 (2011). The number of examined animals also suffered a reduction, going from 28.681 (2007) to 7.747 (2011). The number of positive animals, also accompanied that decrease, from 1627 (2007) to 50 (2011).

CONCLUSÕES:

Regarding the vaccination and the serum diagnostic test, those results might have varied in function of the lack of investment on surveillance actions of the Control and Eradication Program of Bovine Brucellosis, in the State of Acre, during the studied period.
