“…A total 35 sick and suspected chickens were collected from poultry farms in Ado Ekiti Nigeria; Ekiti State University farm (10), Ago-Aduloju's poultry farms (15) and Federal Polytechnic Ado-Ekiti poultry farms (10). The poultry birds were diagnosed for avian Aspergillosis on the basis of clinical signs such as emaciation, difficulty in breathing, appeared unthrifty and weak, with drooping wings and may fail to attempt to escape if pursued [11].…”

“…Lungs are most frequently involved in chicks or poults up to 6 weeks old. Pulmonary lesions are characterized by white to yellow plaques and nodules which are few mm to several mm in diameter; occasionally, mycelial masses may be seen within the air passages [10]. Thus this study aim to isolate the common agent of Aspergillosis in the poultry farms within Ado Ekiti metropolis Nigeria using cultural and molecular techniques.…”

Aim: The study was carried out to isolate and identify Aspergillus species from commercial birds with suspected aspergillosis in the poultry farms within Ado Ekiti metropolis Nigeria. Place and Period of Study: The study was carried out in the Department of Microbiology, Faculty of Science, Ekiti State University Ado Ekiti, Nigeria in August 2016. Methodology: A total of 35 sick/suspected birds were collected randomly from three poultry farms. At Ago-Aduloju poultry farms, 15 samples were randomly collected from 1000 birds while at Ekiti State University poultry farms, 10 samples were randomly collected from 500 birds. At Federal Polytechnic Ado Ekiti poultry farms, 10 samples were randomly collected from 700 birds. The bird’s selection was on the basis of clinical signs and symptoms such as difficulty in breathing, weight loss, drooping of wings and exercise intolerance. Swab samples were collected from each suspected/sick bird for mycological culture and molecular characterization of the isolates from each bird was carried out. The isolates were identified based on the color of the culture on Potato Dextrose Agar and microscopic examination. Molecular identification was done using 23S Ribosomal RNA Gene and Partial Sequence. Results: Six fungal strains that showed similar morphological and cultural characteristics of Aspergillus species were isolated. The isolates were coded ASP 1, ASP 2, ASP 3, ASP 4, ASP 5, and ASP 6. The identified organisms were; Aspergillus fumigatus qH 107 (ASP 1), Aspergillus fumigatus qH 107 (ASP 2), Aspergillus flavus M09 (ASP 3), Aspergillus flavus UOMS6 (ASP 4), Aspergillus fumigatus qH 107 (ASP 5), Aspergillus flavus qH 107 (ASP 6). Conclusion: It is evident that Aspergillus species were predominant in poultry farms selected in this study. Necessary precaution should be put in place to prevent the spread of aspergillosis. Poultry farmers are advised to avoid damp environments, moldy feeds, dry and dusty litters. Adequate ventilation should always be provided in poultry farms to prevent Aspergillosis.

Black swans (Cygnus atratus (Latham) 1790), which was native in Australia, were distributed all over the world and artificially reared. Aspergillosis is non-contagious fungal disease infected in some poultries and wild birds and the important agent are some of Aspergillus species. Infection by Aspergillus species results in respiratory disease in poultry and wild birds. The disease is generally caused by Aspergillus fumigatus and Aspergillus flavus. This study was proceeded to document the clinical signs and lesions of Aspergillosis in artificially breeding black swan in DPR Korea, isolate and identify the causative fungi from lesions. Black swans at Swan Breeding Center in Taedong County, South Pyongan Province, DPR Korea were investigated. The infected swans died suddenly after two or three days when they lost appetite and had symptoms of dyspnea, sudden retraction or deformity of their neck and abnormal walking. The infected black swans had white fecal diarrhea. The fungal hyphae were also observed in the eyes. Here, we confirmed the clinical cases of Aspergillosis in artificially breeding black swans in DPR Korea and A. flavus was isolated in Potato Dextrose Agar (PDA) and identified morphologically from fungi cultivated in Malt Extract Agar (MEA), Czapek Yeast Extract Agar (CYA) and Czapek Dox Agar (CZ). The morphological characteristics like colony colors were similar with the findings of who isolated Aspergillus flavus from maize and soil in Kenya. The microscopic characteristics of fungus isolated from aspergillosis lesions in Black swans were investigated. The morphologically identified fungus was confirmed as A. flavus by sequencing of PCR product of 600bp fragment with primers ITS1/ITS4 and Blast analysis.

In this study, we aimed to determine the presence of pulmonary aspergillosis by histopathological and microbiological methods in geese that are economically grown in the Kars region of Turkey. Totally 150 lung tissue samples of geese, average age of 9 weeks, which died between 2013 and 2020 and were brought to our department were included in the study. In order to reveal the presence of Aspergillus fungi, Periodic acid-Schiff (PAS) staining was applied to the sections as suggested by manufacturer. The microbiological examination of the tissue samples was carried out by the standard mycological culture technique on Sabouraud Dextrose Agar and by the phenotypical characterization of the emerged cultures. We observed large and small multifocal yellowish-white nodular structures in the lungs and air sacs macroscopically. In the histopathological examination of the lung tissues, we detected granulomatous structures with varying numbers and sizes. We diagnosed the Aspergillus agents in 20 (13,33%) of the tissue samples by detecting structures resembling typical tree branches in the middle of granulomatous structures with PAS staining. An identical positivity was obtained by the microbiological method and the emerged agent was solely identified as Aspergillus fumigatus with the growth pattern and macroscopic and microscopic morphological features. In conclusion, we found the presence of aspergillosis as 13,33% by histopathological and microbiological methods in geese which were brought to our department between 2013-2020. Based on these data, we concluded that aspergillosis is one of the most important infectious diseases among the goose deaths in the Kars region of Turkey
