This study was conducted to determine the seroprevalence of egg drop syndrome ‘76 in chickens and guinea fowl sampled from commercial farm and live bird market in Maiduguri, Borno State. Haemagglutination inhibition (HI) test was used to detect EDS ‘76 antibodies. Out of the 154 sera analysed, 37 (24.03%) tested positive for EDS’ 76 antibodies with prevalence rate of 27.05 % in live bird market and 12.50% in commercial farm. Analysis of variance (ANOVA) revealed that there was a significant difference between the locations (P˂0.0001). The mean EDS ‘76 antibody titre in poultry sampled from live bird market was 17.508±3.464 log2, while in commercial farm was 16.00±7.603 log¬2. Chickens and guinea fowl has a prevalence of 24.50% and 0% respectively and mean EDS ‘76 antibody titre of 17.536±3.211 log2 and 0.000 respectively. Local chickens have a higher seroprevalence rate of 27.73% and mean EDS ‘76 antibody titre of 17.950±3.542 log2 than layers from exotic breed which have a seroprevalence of 12.50% and mean EDS ‘76 antibody titre of 16.00±7.603 log¬2. The result obtained from this study showed that chickens from Maiduguri have circulating antibodies to EDS ‘ 76 and it is therefore recommended that EDS ’76 be included as a differential to cases with history of drop in egg production.
