Necropsy was performed, and a large, single nematode was discovered in a cranial air sac
over the syrinx, consistent with the intrathoracic portion of the clavicular air sac
Fungal culture of the air sac
identified fungal colonies consistent with Aspergillus section Nigri.
In contrast, our data indicate that pandemic (H1N1) 2009 virus cannot productively infect chickens at the ages of 1 week (air sac
inoculation), 12 weeks (contact exposure, intravenous inoculation), or 15 weeks (oculo-oronasal inoculation), or turkeys at the ages of 1 week (air-sac inoculation) and 4 weeks (contact exposure) because neither virus excretion nor seroconversion was observed during the 10-day observation period.
We report a case of air sac
nematode (Serratospiculum tendo) infection in an adult male Austral peregrine falcon (Falco peregrinus cassini) admitted to a rehabilitation center in Mendoza Province, Argentina, in 2017.
Sampling procedure: Trachea (154), lungs (113) and air sacs
(113) were collected from each bird at necropsy and divided in two halves, one for immediate inoculation in Fray's broth on spot and other preserved for DNA extraction.
The subcutaneous emphysema noted after surgery in both cases is likely a result of trauma to the air sac
and incomplete closure of the body wall at the time of surgery.
To find out how having an air sac
changed the sounds produced, Dr de Boer created plastic models of the mouth, tongue and throat and forced air down them to produce different vowel sounds.
They introduced a variety of nano-scaled particles (a nanometer is one-billionth of a meter) into the air sac
These conditions were conducive to fungal propagation on the air sacs
due to localized disruption of abdominal air sac
epithelial immunity by implantation of metastatic neoplastic cells.
Postoperatively, normal breathing was confirmed and the air sac
cannula was removed.
Image quality and diagnostic potential improve with organ enlargement and resulting air sac
displacement, as well as with fluid accumulation in the coelomic cavity.
Histologically, within the air sacs
and the air sac
walls, multiple longitudinal and cross sections of adult male and female nematodes were observed.
