We studied zoonotic transmission of Chlamydophila psittaci in 39 breeding facilities for Psittaciformes (cockatoos, parrots, parakeets, lories) that frequently used antimicrobial drugs. Genotypes A or E/B were detected in 14.9% of humans at these facilities. Information on antimicrobial drug use in Psittaciformes and a C. psittaci vaccine are urgently required.

The virus of parrots and parrakeets discovered by Pacheco, Bier, and Meyer is unrelated to the agent causing psittacosis either in birds or in man. The virus is fairly species-specific and manifests itself chiefly by the production of areas of focal necrosis in the liver and acidophilic intranuclear inclusions in affected cells.

Three complete genomes of beak and feather disease virus (BFDV) were recovered from wild twenty-eight parrots (Polytelis anthopeplus monarchoides). The genomes consisted of 1,996 bp with 1,934 identical sites and a typically content stem-loop structure between ORF1 and ORF2. This is the first report of BFDV infection as well as the complete genome sequences for this host species globally.

Members of the order Psittaciformes (parrots and cockatoos) are among the most long-lived and endangered avian species. Comprehensive data on lifespan and breeding are critical to setting conservation priorities, parameterizing population viability models, and managing captive and wild populations. To meet these needs, we analyzed 83, 212 life history records of captive birds from the Internati...

BACKGROUND Premedication is rarely used in avian species. The aim of this study was to evaluate the effect of premedication on the quality of sevoflurane induction and anaesthesia in parrots. We hypothesised that premedication would facilitate handling and decrease the minimum anaesthetic dose (MAD). Thirty-six adult parrots were randomly distributed in three groups: group S (n = 12) was premed...

The concept of sentience, which concerns the capacity to have feelings, involves cognitive concepts and awareness. The cognitive capacities of parrots, corvids, cows, pigs and sheep are substantial. All vertebrates, including fish, are shown to have pain systems. There has been rapid development in animal welfare science, including pain assessment. Examples of new pain indicators in sheep and o...

Contrafreeloading (CFL) is a concept that describes the preference of an animal to work for food even when identical freely available, and reflects intrinsic motivation engage in foraging-related activities. However, altered brain neurochemistry, which can be induced by chronic exposure suboptimal living environment, may affect this animals with abnormal repetitive behaviours (ARBs), including ...
