Fig. 4From: Purification of recombinant IpaJ to develop an indirect ELISA-based method for detecting Salmonella enterica serovar Pullorum infections in chickensChanges in levels of antibodies against IpaJ in antiserum from S. Pullorum-infected chickens. Antiserum samples from ten S. Pullorum infected chicken were subjected to the detection of antibodies against IpaJ using the established indirect ELISA assay. The antisera were collected from the first week after inoculation to the twelfth week. (*: p < 0.05; **: p < 0.01; ***: p < 0.001)Back to article page
