  1. *Spleens of mice 5, 7 and 9 were positive also by parasite cultivation; in other mice cultivation attempts were not done.
  2. Quantity of parasites was tested by qPCR and scored as + (<102), ++ (102-103), +++ (103-104), ++++ (104-105), +++++ (>105).
  3. neg., negative, n.d., not done; p.i., post infection.
