“…This condition was first reported in kiwi in 1973 (Smith et al 1973), and is commonly found incidentally in kiwi at post mortem, especially those in captivity. The disease is characterised by the focal accumulation of dust-laden macrophages in bronchial walls (NZWHC 2006).…”

“…Birds most likely to be affected are those kept on dry sandy substrates containing a large proportion of silica. The olfactory behaviour of the kiwi and the distal placement of their nostrils on the upper bill presumably predispose kiwi to this disease (Smith et al 1973;Boardman 1995).…”

“…In an experimental study, Anderson et al [28] examined the effects of dust and ammonia on the respiratory system of turkeys and found no pathological changes in most cases. It has been reported that pneumoconiosis in birds occurs related to air pollution such as housing in dusty, enclosed locations, and dust from city traffi c or nearby industrial facilities [9,20,22]. There was no industrial activity causing heavy air pollution in the region where this fl ock is located, and also the fl ock was far from the city traffi c. Detailed anamnesis indicated that both the fl ock and the houses in the vicinity were heated by coal stoves.…”

“…However, reports of pneumoconiosis have been described in domestic and wild mammals [17][18][19]. Pneumoconiosis has been reported in avian species such as kiwi, rhea, ostrich, touraco, swan, owl, crane, duck, eagle, pheasant in San Diago Zoo and Dhaka Zoological Park, and in hens [9,10,[20][21][22]. However, the disease has not been reported in turkey which is an important species in poultry industry.…”

Concurrent Occurrence of Lower Respiratory Aspergillosis and Pneumoconiosis in a Turkey Flock

This study describes a concurrent occurrence of lower respiratory aspergillosis and pneumoconiosis in a turkey fl ock. From one fl ock of 1000 turkeys, 4 clinically affected turkeys were examined pathologically and microbiologically. Clinically affected turkeys showed anorexia, lethargy, drooping of the wing, vomiting, dyspnea and open-beak breathing, or sudden dead. Gross lesions were observed in the air sacs and lungs which presented white to yellowish granulomas of varying size. Microscopic there was multifocal granulomatous airsacculitis and pneumonia. At the center of the granulomas, fungal hyphae were clearly highlighted in the lungs and air sacs by Gomori methenamie silver (GMS) staining. In the microbiological cultivation of the affected lungs and air sacs, Aspergillus fumigatus was isolated on Sabouraud dextrose agar. Furthermore, dark black dust accumulations were present in the cytoplasm of macrophages or interstitial tissue in the lungs and air sacs. There were also fi brosis and lymphohistiocytic cell infi ltrations around the particles. Overall, this study could implicated that pneumoconiosis might be a predisposing factor in the development of respiratory aspergillosis in turkeys.

“…In human, extrathoracic anthracosis are rarely reported in the esophagus [5] and liver [6] . This condition is more common in human than animals because they are not in exposure to the occupational conditions in contrast to human cases [2,7] . In animals, Mild pulmonary anthracosis is a common incidental finding in crowded city or those cohabite with cigarette smokers.…”

Pneumoconiosis is an occupational lung disease which occurs by the accumulation of inhaled organic and inorganic particles in the pulmonary parenchyma. These particles interfere with the defense mechanisms of the lungs. This study was designed to describe the gross and histopathological features of pneumoconiosis in the lungs and its relation with occurrence of pneumonia in camels. 150 pneumonic and 100 healthy lungs were examined for pneumoconiosis in pathologic level. Macroscopic lesions of pneumoconiotic lungs were related to pneumonia and no remarkable features of pneumoconiosis were observed in the examined tissues. Pneumoconiosis was diagnosed in 43 out of 150 lungs with pneumonic lesions. Grossly healthy lungs did not show pneumoconiosis. Out of 43 pneumoconiotic lungs, 93% (n=40/43) were associated with interstitial pneumonia. Also, pneumoconiosis occurred in 2.32% (n=1/43) and 4.65% (n=2/43) of lungs with suppurative bronchopneumonia and bronchointerstitial pneumonia, respectively. Histopathologic findings related to pneumoconiosis were characterized by varying degrees of diffuse to nodular fibrosis as well as mild to heavy accumulations of mixed carbon and silicon dusts. Interlobular and interalveolar septa of alveoli were thickened by fibrosis and infiltration of mononuclear inflammatory cells. Crystalline silicon particles were in different shapes including filamentous, oblong and polygonal. Anthraco-silicosis particles were observed inside and outside of macrophages more adjacent to the vessels and bronchioles as well as lymphocytes infiltration. The color of particle aggregations was different from scant gray to brown or dense black, depending on the amount of silicon or carbon dust deposition. In the lungs, areas with prominent deposition of crystalline silica rather than carbon were gray to light brown and focal interstitial fibrosis was occurred. The present study suggests a positive causal relationship between pneumoconiosis and pneumonia. It seems these particles predispose animals to pulmonary diseases especially various type of pneumonia.
