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.
22) found SA[alpha]2,3Gal and SA[alpha]2,6Gal receptors in the bronchi, bronchioli
, and alveoli of chickens and ducks; however, SA[alpha]2,6Gal was dominant in chicken tracheal epithelium, and SA[alpha]2,3Gal, in duck trachea.
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.
