Transfer of immune response to schistosoma mansoni infections between mice by means of parabiosis

Attempts to transfer the Immune response to Schistosoma mansoni infection between two mice by means of parabiosis were tried. Three groups of mice were parabiosed one week, 6 weeks and 8 weeks following infection of one partner. The healthy partners were seperated one week later and infected with cercariae 3 days after separation. Thereafter, they were examined to investigate the affect of induced immunity during the period of parabiosis on the number and morphology of adult worms and number of eggs and pathological lesions in the liver, Evidence of immunity could be detected in animals parabiosed 6 and 8 weeks after infection
