The use of serologic assaysin avian medicine
Seminars in Avian and Exotic Pet Medicine, 2001Co-Authors: David N. PhalenAbstract:Serologic assays exist for viral, bacterial, and fungalinfections of cage and Aviary Birds. This report begins with a review of the mechanics of the most commonly used serologic assays. The remainder describes the serologic assays that are currently available for infectious diseases of cage and Aviary Birds. The strengths, limitations, and interpretation of these assays are discussed.

respiratory medicine of cage and Aviary Birds
Veterinary Clinics of North America: Exotic Animal Practice, 2000Co-Authors: David N. PhalenAbstract:Respiratory diseases are a relatively common cause of illness and death in cage Birds. A diagnostic algorithm is provided based on history, physical examination, and ancillary diagnostic findings that assist clinicians in determining the cause of a bird's respiratory disease. Also included are detailed descriptions of the common respiratory diseases of cage Birds and their treatment.

Body condition and immune response in wild zebra finches: effects of capture, confinement and captive-rearing
Naturwissenschaften, 2001Co-Authors: Erynne L. Ewenson, Richard A. Zann, Graham R. FlanneryAbstract:Behavioural ecologists attempt to predict fitness in Birds from estimates of body condition and immune capacity. We investigated how the stresses associated with capture, confinement and captive-rearing of wild zebra finches ( Taeniopygia guttata ) affected different elements of the immune system and body condition. Wild Birds had higher heterophil:lymphocyte ratios and total leucocyte counts than Aviary Birds, presumably an outcome of mounting specific resistance to pathogens, but this response diminished significantly within 10 days of confinement. Wild Birds had lower phytohaemagglutinin-A (PHA) responses than their Aviary-bred counterparts possibly because energetic costs limited a general resistance response. Wild Birds were heavier and had higher haematocrits than their Aviary counterparts, but had less fat, although just 10 days of captivity significantly increased fat levels. Measures of body condition were of limited use for predicting immune responsiveness. We conclude that the different elements of the immune system and body condition respond independently, and often unpredictably, to many ecological and behavioural stressors.

deaths in Aviary Birds associated with protozoal megaloschizonts
Veterinary Record, 2006Co-Authors: Mark F Stidworthy, Andrew GreenwoodAbstract:SIR, — We read with interest the letter from Pennycott and others ( VR , October 7, 2006, vol 159, pp 499-500) regarding the emergence in Scotland of disease in parakeets attributable to protozoal megaloschizonts. Their descriptions closely parallel our recent experience in West Yorkshire.

Deaths in Aviary Birds associated with protozoal megaloschizonts.
Veterinary Record, 2006Co-Authors: T. W. Pennycott, Catriona Macintyre, Duncan Macintyre, A M Wood, Tony PattersonAbstract:SIR, — Deaths associated with large, multi-chambered tissue schizonts described as megaloschizonts have been reported in psittacine Birds kept in aviaries in the southern half of Great Britain ([Fowler and Forbes 1972][1], [Smith 1972][2], [Walker and Garnham 1972][3], [Simpson 1991][4]), usually
