Abstract: Brucellosis is an economically important infection of livestock due to the reproductive problems it causes and also the risk to the public health. A study of bovine brucellosis was conducted using Indirect Enzyme linked immunosorbent Assay (i-ELISA), a serological test to determine the disease status in Andhra Pradesh state for the past five years. A total of 8849 sera samples from Bovines were screened during past five years (2017-18 to 2021-22. The percentage of positivity is 8.13%, 13.32%, 27.41%, 25.37% and 9.58% respectively starting from 2017-18 to 2021.22. The present study reveals that initially there is increase in the percent positivity later there is a descending pattern due to phased Brucella vaccinations of Bovine population and culling or separation of positive reactors for Brucella.
