Molecular characterisation of an avihepadnavirus isolated from Psittacula krameri (ring-necked parrot)

Archives of Virology, 2011
Avihepadnaviruses have been documented previously in ducks, herons, geese, storks and cranes. Here, we describe the full genome of a new avihepadnavirus isolated from Psittacula krameri (ring-necked parrot) in Poland. The parrot hepatitis B virus (PHBV) genome (3042 bp) shares

Seasonal Changes in Neuronal Spacing of Hippocampus of Psittacula krameri (Scopoli, 1769)

The National Academy of Sciences, India, 2013
Neural plasticity in avian hippocampus is accompanied by seasonal changes. The previous studies have reported that the fluctuation in season results in changes in thickness of dendrite, spine turnover and morphology of spine in hippocampus of birds whereas the present investigation indicates that neuronal spacing in hippocampus of birds is also ...
