    Abstract

    ELISAs using recombinant parasite polypeptides as antigens were developed to measure Toxoplasma gondii-specific antibodies in the sera of sheep and cats. Compared with an ELISA based on traditional parasite antigen, the ELISA for sheep sera had a sensitivity of 79% and a negative predictive value of 80%, and the ELISA for cat sera had a sensitivity of 100% and a negative predictive value of 100%. Both ELISAs had specificities of 100% and positive predictive values of 100%. These ELISAs appear to be a useful cost-effective alternative to ELISAs based on traditional parasite antigen for the measurement of T. gondii-specific antibodies in the sera of sheep and cats.
