Avian bornaviruses were first described in 2008 as the causative agents of proventricular dilatation disease (PDD) parrots and their relatives (Psittaciformes). To date, 15 genetically highly diverse avian covering at least five viral species have been discovered different bird orders. Currently, primary diagnostic tool is detection RNA by conventional or real-time RT-PCR (rRT-PCR). One drawbac...
Hybridization in the wild is a relatively common occurrence between species of parrots (Psittaciformes) within same genus. However, recent publication documented successful production hybrids following mating parrot from different genera, which was only such case known to authors. Here, I summarize other cases apparent intergeneric hybridization that have been published low-impact regional jour...
The last 20 years have seen a resurgence in systematic studies of parrots (Aves: Psittaciformes). Principally but not solely molecular in nature, this body of work has addressed the circumscription of higher level groupings within the Psittaciformes and relationships among them. Stability has now emerged on many formerly contentious matters at these levels. Accordingly, we consider it appropria...
Mitochondrial genomes are generally thought to be under selection for compactness, due to their small size, consistent gene content, and a lack of introns or intergenic spacers. As more animal mitochondrial genomes are fully sequenced, rearrangements and partial duplications are being identified with increasing frequency, particularly in birds (Class Aves). In this study, we investigate the evo...
Kajerová V. , V. Baru‰: Psittacine birds (Aves: Psittaciformes) as new hosts of Baruscapillaria obsignata (Nematoda: Capillariidae). Acta Vet. Brno 2005, 74: 571-574. The first record of Baruscapillaria obsignata (Capillariidae) in small intestine of three psittacine birds (Barnardius zonarius, Agapornis roseicollis and Melopsittacus undulatus) kept in captivity in the Czech Republic is describ...
