Occurrence of avian bornavirus infection in captive psittacines
in various European countries and its association with proventricular dilatation disease.
Slight sexual dimorphism occurs in other monogamous psittacines
, although detailed information is available for only a few species (Collar 1997, Masello and Quillfeldt 2003).
Venipuncture was performed on a group of 36 psittacine
birds as part of routine health checks in a research aviary (Texas A&M University, College of Veterinary Medicine, College Station, TX, USA).
Since then, 6 different ABV genotypes have been detected in psittacines
Thirteen species of psittacines
used the clay lick in the early morning period (before 0730 hrs, Table 1).
Avian pox appears to be a rare condition in psittacine
birds located in the United States and primarily causes ocular or upper digestive tract lesions in affected birds.
To investigate vertical transmission of ABV, we examined 30 dead-in-shell embryos of various psittacine
species that originated from ABV-infected flocks with a history of PDD.
Parrots eat ripe and unripe fruits, and many species consume large amounts of immature and mature seeds, making some psittacines
effective pre-dispersal seed predators (Desenne 1994, Pizo et al.
This is the first report of mesothelioma in a psittacine
PCR identified Haemoproteus sequences in the blood of 3 of 26 psittacines
, although parasitic structures were not identifiable in blood smears.
Seasonal movements are likely a response to breeding and availability of specific food resources similar to other psittacines
(Symes and Perrin 2003).
