Serological evidence of egg drop syndrome’1976 (EDS’76) in free-range chickens at chicken market sites in Jos, Nigeria

摘要

Serological evidence of EDS'76 virus in free-range chickens at the various chicken markets (Kasuwan kaji, New market, Gada biyu, and Kugiya) located in Jos and its environs was investigated through antibody detection. The serum samples randomly collected from chickens were assayed for antibodies against EDS'76 virus by haemagglutination-inhibition (HI) test. It was observed that 292 (15.2%) of the 1920 sera tested were positive for EDS'76 antibodies with HI titres ranging between log22 and log2128 and geometric mean titre (GMT) between 4.9 and 13.1. Of this number of positive sera, 150 (51.4%) were from Kasuwan kaji, 90 (30.8%) from Kugiya, 30 (10.3%) from Gada biyu, and 22 (7.5%) from New market. This finding indicates activities EDS 76 virus among the free-range chickens in the study area.
