ELISA of anti-C2 antibodies produced in cattle post infection. Four and a half months after the last immunization booster, all the cattle were infected intra-dermally with T. congolense IL3000 (103 parasites per animal). The pre-patent period was 9–11 days. The arrows show the ‘booster effect’ of infection around 2 weeks post patency. The arrow on the x-axis shows the time of treatment with diminazene aceturate.
