Pyrimethamine/sulfadoxine Treatment against Mixed Avian-haematozoa Infections in Imported Tengmalm's Owls ( Aegolius funereus )Daisuke FUKUI†*, Koichi MURATA, Gen BANDO, Masao KOSUGE
SUMMARY Three imported wild Tengmalm's owls (Aegolius funereus) from Russia were less active and
unable to fly after transfer to an outside aviary. Blood-smear examinations revealed mixed infections
with avian haematozoons (Haemoproteus sp., Leucocytozoon sp, Trypanosoma sp.). One
owl died, but the clinical conditions of the other two improved after treatment with pyrimethamine/sulfadoxine.
Although this drug combination was effective against both Haemoproteus and Leucocytozoon infections,
the later haematozoon persisted after treatment. Treatment against Trypanosoma infection was ineffective.
From the standpoint of wildlife management, haematozoic infections in imported exotic birds should be
carefully considered as a source of introduced pathogens.
