OBJECTIVE: To establish an animal model of Sparganum mansoni (plerocercoid larva of S. mansoni) infection in mice and observe the changes of blood routine examinations and serum anti-sparganum antibody levels after the infection.
METHODS: The spargana tapeworms were collected from frogs, and 25 Kunming mice were orally infected with the Sparganum tapeworms (3 tapeworms/mouse). Two days before the infection and 2, 7, 14, 21, 28, 35, 42 days and 49 days after the infection, the peripheral blood samples of mice were collected for the blood routine examinations and the detections of anti-S. mansoni IgG antibody with ELISA. Forty-nine days after the infection, all the mice were sacrificed to find out the Sparganum tapeworms in the bodies of mice.
RESULTS: The count of the total white blood cells was significantly elevated on the second day of the mice infected with Sparganum. The serum anti-Sparganum antibody was detected on the 14th day of the infection in some mice, and on the 21st day of the infection, the serum anti-Sparganum antibody was detected in all the mice. After the mice were sacrificed, the Sparganum tapeworms were found out in many tissues and organs, and especially in the subcutaneous tissues and muscle.
CONCLUSIONS: The establishment of animal model of Sparganum infection is successful in mice with the oral method, and white blood cells and serum specific IgG antibody detection can be used as auxiliary diagnosis methods of S. mansoni infection.
