Minga, U.M. | Wray, C.
An ELISA using lipopolysaccharide antigens prepared from Salmonella gallinarum and S enteritidis was developed for the serological diagnosis of fowl typhoid and S enteritidis infection in poultry. There was good agreement between the results of the ELISA and conventional serological tests when samples from naturally infected birds and S enteritidis immunised birds were tested. Some cross reactions were observed when serum samples from S typhimurium infected birds were tested by ELISA. Subsequently a disc ELISA, using filter paper discs, was developed to facilitate sampling and testing of poultry. There was good correlation between the results of the disc and serum ELISAs and the test is recommended for the field testing of birds.
