Disease relevance of Cockatoos

  • The purpose of this experiment was to examine the physiological responses of adult cockatiels at maintenance to dietary vitamin A (VA) concentrations, and to identify concentrations associated with deficiency and toxicity [1].

High impact information on Cockatoos

  • Pigeon ovomucoid was equipotent on a molar basis with globoside, and the pigeon, dove, and cockatiel egg white preparations were equipotent with each other in P-fimbrial inhibition [2].
  • To develop reliable diagnostic methods, the region encoding the BFDV capsid protein C1 was cloned from an infected sulphur-crested cockatoo (Cacatua galerita) [3].
  • CONCLUSIONS AND CLINICAL RELEVANCE: DMSA and Ca EDTA are effective chelating agents in cockatiels [4].
  • We conclude that egg production in incubating cockatiels is influenced by feedback from the number of eggs in the nest and that clutch termination may be signaled by rising prolactin levels in females [5].
  • As part of a comparative morphological study, the fine structure of the retinal epithelium (RPE), choriocapillaris and Bruch's membrane (complexus basalis) has been investigated by light and electron microscopy in the galah (Eolophus roseicapillus), an Australian cockatoo [6].

Chemical compound and disease context of Cockatoos


Biological context of Cockatoos

  • Peak water intake in the cockatoos more than quadrupled, and remained increased for 23 days after cessation of gentamicin administration [8].
  • This protocol was used to document a seasonal sex difference in stimulated T4 values--females responded with higher T4 values than those in males in summer--and a stress-induced depression of baseline T4 values was detected in a group of cockatiels with normal TSH response [9].
  • Platinum pharmacokinetics in sulphur-crested cockatoos (Cacatua galerita) following single-dose cisplatin infusion [10].
  • As clutch size in Cockatiels may also be limited by rising prolactin levels, such manipulations may be effective in stimulating egg production in parrots [11].

Anatomical context of Cockatoos


Associations of Cockatoos with chemical compounds


Gene context of Cockatoos

  • In February and March 1984, Cryptococcus neoformans was detected in the manure and ambient air of a volery in the Berlin Zoo in which a Palm Cockatoo (Probosciger aterrimus) was kept [16].
  • In conclusion, in cockatiels, nest inspection and laying are characterized by high LH levels while high Prl levels occur during incubation and feeding of nestlings in both males and females [17].
  • Compared with findings in healthy cockatoos, cockatoos with FBD had significantly lower serum protein concentrations, and results of serum protein electrophoresis indicated that birds with FBD had significantly lower concentrations of prealbumin and gamma-globulin fractions [13].
  • They included Wrinkled Hornbill (Aceros corrugatus), Great Argus Pheasant (Argusianus argus), Black Swan (Cygnus atratus), Swan Goose (Anser cygnoides), Marabou Stork (Leptoptilos crumeniferus), and Moluccan Cockatoo (Cacatua moluccencis) [18].
  • Duodenal beta-actin and 15,15'-dioxygenase mRNA expression was similar to that of growing chickens, and greatest for cockatiel chicks fed 0 IU VA (p<0.01) [19].
