The search has been performed on blood samples from cows with
different ages and various multi-productive purposes from a
number of farms to detect sera-prevalence percentage of brucella
abortus infection in cows using Competitive Enzyme Linked
I
mmune Sorbent Assay. The test results have shown general
serum spread by the percentage 5882%. The rate of antibodies of
serum spread in the cows in different farms under study have
been between 0.00% and 16.66%.
