and alveolar spaces are filled by large amount of neutrophils associated with necrosis of the respiratory epithelium and fibrin deposition.
The density of leukocytes/unit area (130 [micro][m.sup.2]) was determined by counting the number of cells on the integrating eyepiece that fell into areas of the bronchioli
and distal lung parenchyma using the ImageJ Program.
A novel avipoxvirus caused diphtheritic lesions in the esophagus of five and in the bronchioli
of four Magellanic penguins (Spheniscus magellanicus), and also cutaneous lesions in 8 Magellanic penguins housed in outdoor enclosures in a rehabilitation center at Florianopolis, Santa Catarina State, Brazil.
In general, potential transmission of mycobacteria should not be underestimated; in this case, intracytoplasmic bacilli were detected in the bronchioli
of the ferret's lung, making airborne spread of mycobacteria and infection of humans possible.
(1,2,5) The Cumbo sign is seen when bronchi/ bronchioli
are eroded and air enters into the cyst and gets trapped among the endocyst membranes.
From the liver, migrating larvae are pumped by the heart to the lungs where they are expelled into the bronchioli
and coughed up into the mouth.
However, recent studies have shown that despite SA[alpha]2,3Gal and SA[alpha]2,6Gal receptors in pig respiratory tracts, SA[alpha]2,3Gal is found only in the smaller airways (bronchioli
and alveoli) and not in the trachea (20,21).
Histopathologic studies showed total destruction of the respiratory epithelium covering the bronchi and bronchioli
, together with abundant gram-positive cocci, absence of viable polymorphonuclear cells, and extensive necrosis of the alveolar septa.
