Hatt, J M; Zollinger, E; Boehler, A; Hofer, M; Steinmetz, H W; Clauss, Marcus (2009). Collection and analysis of breath and breath condensate exhaled by feral pigeons (Columba livia) and chickens (Gallus domesticus). Veterinary Record, 165:469-473.

Abstract

Samples of exhaled breath and breath condensate were collected from 20 feral pigeons (Columba livia) while they were anaesthetised and intubated, and when they were kept unanaesthetised in an acrylic box. Samples were also collected from six chickens (Gallus domesticus) while they were kept in an acrylic box. The samples were analysed for pH, nitric oxide (NO), hydrogen peroxide and leukotriene B4. The volume of condensate collected from the pigeons was independent of bodyweight and significantly more (1·66 [0·64] ml/kg) was obtained while they were in the acrylic box than when they were intubated (0·87 [0·32] ml/kg). The mean volume collected from the chickens was 0·15 (0·06) ml/kg. Cooled samples had higher concentrations of NO than uncooled samples. The pH of the samples of condensate collected from birds in the acrylic box were significantly higher (7·9 [0·3]) than those from the intubated birds (5·3 [0·1]), and samples from the chickens had significantly higher pH values than samples from the pigeons (8·2 [0·2] v 7·9 [0·3]).

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
