This study involved the testing of 3,245 livestock samples using the Rose BengalPlate Test (RBPT), Indirect Enzyme-Linked Immunosorbent Assay (i-ELISA) and genus-specificpolymerase chain reaction (PCR) markers for molecular diagnosis of the disease. In the tested samples seroprevalence was 5.06% (CI: 1.96-8.15) using the RBPT test and 6.88% (CI: 1.98-11.78) using the i-ELISA test while the cumulative seroprevalence (RBPT and i-ELISA) was 3.63% (CI: 0.44-6.83). The prevalence of the disease was 1.27% (CI: -0.56-3.11) when tested using the molecular markers.The highest prevalence of Brucellosis brucellosis was detected in Cattle (7.00%, 3.22%) followed by camel (5.50%, 2.50%), buffalo (2.66%, 0.00%),sheep (2.43%, 0.41%), and goat (0.58%, 0.23%) when serological (cumulative) and molecular diagnosis are considered as preferred methods of detection. Cattle (3.22%) and camels (2.50%) also showed high prevalence of disease when tested using molecular markers. The results of this study revealed that cattle, camel and sheep brucellosis is prevalent in the study areas.
