A suitable air sac
sample was not detected for examination.
The abdominal air sac
(A) thickened by friable tan to grey exudate.
([dagger]) Three juvenile chickens and turkeys inoculated through the air sac
were killed on days 0, 2, 4, 6, 8, and 14 posinoculation, and left and right lung lobes were removed for analysis by real-time reverse transcription-PCR.
Molecular characterization: Polymerase chain reaction (PCR) was used for detection of MG in organs (trachea, lungs and air sacs
) of infected birds as described by Santha et al.
(17,18) The intestinal peritoneal cavity contains the urogenital organs, gastrointestinal tract, spleen, and left and right abdominal air sacs
. (17,18) The only connection between the different coelomic cavities occurs between the intestinal peritoneal cavity and the left dorsal hepatic cavity.
Some of the models contained an air sac
, the Daily Mail reported.
The lung-on-a-chip microdevice takes a new approach to tissue engineering by placing two layers of living tissues-the lining of the lung's air sacs
and the blood vessels that surround them-across a porous, flexible boundary.
The right and left testes were enlarged, approximately 3 X 2.5 X 1.5 cm, and soft with multifocal tan ridges compressing the tunica albuginea and associated abdominal air sacs
. On cut sections, the testicular parenchyma moderately bulged and occasional irregular soft necrotic areas were present within the parenchyma (Fig 2A).
Tracheal endoscopy revealed an obstruction of approximately 90% of the tracheal lumen, in addition to mild suspected aspergillosis of the air sacs
. Tracheal resection and anastomosis were performed, during which 1.5 cm of abnormal trachea was removed.
Marek's disease, or leucosis, may result in gonadal neoplasia, especially in chickens, leading to massive enlargement of the reproductive organs and subsequent air sac
A total of 20-30 nematodes, approximately 20-30 cm in length, were found in the coelomic cavity and in the thoracic and abdominal air sacs
, which were diffusely opaque and thickened.
Additionally, administration of amphotericin B, as a nebulization agent, often is recommended, especially for cases with significant air sac
