SEROLOGICAL DIAGNOSIS OF SALMONELLA SEROTYPE ENTERITIDIS INFECTIONS IN POULTRY BY ELISA AND OTHER TESTS

Serological methods have increasingly been used for the detection of invasive Salmonella serotypes including enteritidis in poultry. Different types of ELISA, particularly indirect or double antibody-blocking assays using a variety of antigens such as lipopolysaccharide, flagella and SEF14 fimbrial antigen are used as part of control programmes in a number of countries. There are many advantages to using such assays for preliminary screening of flocks prior to using bacteriological culture methods.
