The Effects of Human Presence, Restraint, and Stressed Neighbors on Corticosterone Levels in Domesticated Budgerigars (Melopsittacus undulatus)

Zoo Biology, Volume 45, Issue 1, Page 37-45, January/February 2026.
Female budgerigars (Melopsittacus undulatus) did not significantly elevate their plasma corticosterone levels in response to human presence at the beginning of the experiment. However, plasma corticosterone was significantly elevated by restraint stress, the return of a neighbor that received restraint stress, and human presence at the end of the ...

Zoonotic atypical pneumonia due to Chlamydophila psittaci: First reported psittacosis case in Taiwan

Journal of the Formosan Medical Association, 2013
Human psittacosis caused by Chlamydophila psittaci is one of the most common zoonotic atypical pneumonias featuring pulmonary as well as extrapulmonary infections. Most of the cases involve avian contact history especially with psittacine birds.

Distinct 5′ UTR Requirements for Translation of the Bicistronic X/P mRNA Among Avian Orthobornaviruses

Microbiology and Immunology, Volume 70, Issue 2, Page 80-90, February 2026.
ABSTRACT Orthobornaviruses express X and the phosphoprotein (P) from a bicistronic X/P mRNA, and these proteins regulate polymerase activity. In mammalian orthobornaviruses, the 5′ untranslated region (5′ UTR) of the X/P mRNA controls the translational balance between X and P and thereby promotes efficient replication.

Contamination by Aspergillus flavus and A. fumigatus in sunflower seeds used in psittacine bird food [PDF]

Biotemas, 2010
Widely distributed in food for psittacine birds due its low price, high palatability, and cultural reasons, the Helianthus annuus, called sunflower, is proving important in clinical influenza as a result of excess calories and high incidence of ...

Evaluation of Intraosseous Excretory Urography Using Iodixanol for Renal Imaging in Budgerigars (Melopsittacus undulatus)

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This study demonstrates that intraosseous injection of iodixanol into the proximal tibiotarsal bone provides a reliable, safe, and practical method for diagnostic excretory urography in budgerigars. The technique offers clear visualisation of renal structures and can be an alternative when intravenous access is limited in avian patients.

Gestational Psittacosis in a Montana Sheep Rancher

Emerging Infectious Diseases, 1997
In humans, psittacosis is primarily a flulike illness following exposure to psittacine birds. In rare cases, pregnant women exposed to Chlamydia psittaci can contract gestational psittacosis: atypical pneumonia, sepsis, and placental insufficiency ...

Factors impacting the complexity of the leporid intracranial joint

Journal of Anatomy, Volume 248, Issue 1, Page 28-39, January 2026.
Anatomy of the intracranial joint and the 2D semi‐landmarks used to capture complexity in the intracranial joint. (a) The intracranial joint can be seen here (in red) between the parietal and occipital dorsally and the basioccipital and basisphenoid ventrally. In hares (as in this figure) the interparietals are fused to obliteration.

Avian Bornavirus in Free-Ranging Psittacine Birds, Brazil

Emerging Infectious Diseases, 2014
Avian bornavirus (ABV) has been identified as the cause of proventricular dilatation disease in birds, but the virus is also found in healthy birds. Most studies of ABV have focused on captive birds.

Structural Insights Into the Nuclear Import of Marek’s Disease Virus Large Tegument Protein

Advances in Virology, Volume 2026, Issue 1, 2026.
Marek’s disease (MD) is a highly contagious neoplastic disorder of poultry caused by MD virus (MDV; gallid alphaherpesvirus 2 [GaAHV2]). Infection results in profound immunosuppression, neurological dysfunction, and the development of malignant T‐cell lymphomas.
