title: [The effect of toxoplasma antibodies after reinfection with T. gondii. II. Communication: investigations over the incidence of toxoplasma in peripheral blood after primary and secondary infection (author's transl)].
abstract: After reinfection, parasites could be detected through transfusion of tail blood to healthy mice between 24 and 100 to 352 hours. A time point beyond this was not examined. Parasitaemia could be frequently established between 68 and 76 hours post reinfection. Infection immunity in mice does not protect against reinfection by Toxoplasma. It occurs after oral infection inspite of the presence of humoral antibodies. The parasites spread by blood circulation and increase the titer by one or two titer steps in the SABIN FELDMAN test.
