Virulent Avian Giardia duodenalis Pathogenic for Mice.
Early in 1995, a sulphur-crested cockatoo captured in the wild died along with several other cage mates, apparently of an overwhelming, acute infection of Giardia. Trophozoites isolated from the dead bird and established in traditional Giardia axenic medium were infective to mice and established chronic infections associated with weight gain impairment. Genetically and morphologically, the Giardia isolated from the bird belonged to the duodenalis group. Here, Jacqui Upcroft, Ann McDonnell and Peter Upcroft present data on pathogenic avian Giardia with he potential to contaminate watersheds and discuss the implications.
