Application of ELISA and IHA on Detecting the Antibodies Against Toxoplasma Gondii in the Sera of Humans in the Hilly Land of Meizhou in East Guangdong Province

Objective To explore the infection of toxoplasmosis in humans in the hilly land of Meizhou in East Guangdong province. Method Mutual complementary detection was used in serological study with ELISA and IHA. Results There were 1010 people detected in the investigation, and 157 cases were positive in the two methods of anti-toxoplasma gondii serological tests. The positive rate was 15.54%. Among the 157 positive cases, 90 cases were positive in both methods (ELISA and IHA), and the other 67 cases was positive either in ELISA or in IHA. There were 23 cases positive in ELISA but negative in IHA,and 44 cases positive in IHA but negative in ELISA. Conclu-sion The infective rate of toxoplasmosis is higher in the hilly land of Meizhou in East Guangdong province.The results suggest that it is better to use both methods simultaneously than to use one method only in the diagnosis of toxoplasmo-sis.
