Epidemiological situation of bovine tuberculosis in the State of Pernambuco, Brazil
The epidemiological situation of bovine tuberculosis was studied in the state of Pernambuco, Brazil. The state was divided into three regions, and a predetermined number of properties was randomly sampled in each region. In each property, females aged 24 months or older were randomly selected and su...
