The clinical manifestation of acute aspergillosis is usually observed in young birds, often with episodes of outbreaks in poultry farms, whereas chronic aspergillosis is more frequently observed in adult birds TellCharlton et al.

Consequently, it is expected a high genetic diversity of strains inhaled by aapergilose birds. Fungal isolation from respiratory samples has been regarded as being of limited usefulness in the ante mortem diagnosis of aspergillosis in human patients. Multiple-locus variable-number tandem repeat analysis for molecular typing of Aspergillus fumigatus. Clinical Microbiology Reviewsvol. In Southern Brazil, Santos and colleagues reported the presence of Cryptococcus neoformans and Candida spp in the droppings of captive psittacine and passerines.

Direct microscopic exam and histopathology showed septate, hyaline and branching hyphae in tissues and complete asexual reproductive structure of Aspergillus in the air sacs involved.

There were abundant plaque-like caseous and necrotic debris covering the air sacs, with grayish-green fungal colonies on the surface of the air sacs.

Psittacidae Kept in Captivity: Clinical cases of aspergillosis have already been diagnosed in chickens, turkeys, ostriches, rheas, penguins, geese Carrasco et al. In Brazil, some studies have focused avws the diagnosis of aspergillosis in newly hatched birds Lima et al. The abes signs are usually nonspecific and related to anorexia, weight loss, lethargy, or respiratory system impairment rhinitis, dyspnea and changes in vocalization. The study considered an m: Aspergillosis is one of the main causes of mortality in both immunocompetent and immunodepressed birds.

The complete profile with eight peaks was found, confirming the A.

The lungs of birds condemned due to airsacculitis were defined as “case”, and the lungs obtained from normal birds from the same batch were defined as “control”.

Specific media were used to observe and identify the macroscopic characteristics of the colonies: Microsatellite genotyping and virulence assessment of Aspergillus fumigatus isolates from white stork nestlings and their environment.

Identification and characterization of Aspergillus fumigatus isolates from broilers

Serosurvey and diagnostic application of antibody titers to Aspergillus in avian species. Among birds displayed in enclosures, Aspergillus niger Respiratory infections are common among the chicken population. This allows fungal conidia to escape from the exhalation air-flow, to deposit on the epithelium and develop focal infection BAUCK, Serosurvey and diagnostic application of antibody titers to Aspergillus in avian species.

Additionally, this study attempted to verify the possibility of a causal association between aspergillosis diagnosis criteria and condemnation due to airsacculitis in broilers through a case-control study. Aspergillus species are ubiquitous filamentous fungi widely distributed in the environment and Aspergillus fumigatus is considered as a major respiratory pathogen for birds. The urea test was performed in Christensen medium, together with a biochemical sugar assimilation and fermentation tests profile Kurtzman et al.
