“…Aspergillosis is a common respiratory disease of aquatic birds in captivity (Converse 2007;Burco et al 2014), including Magellanic Penguins (Xavier et al 2011;Silva-Filho et al 2015). Due to the ubiquitous nature of Aspergillus spp., however, the interpretation of serological results is challenging because there is a high background seroprevalence in healthy individuals (Savelieff et al 2018). Furthermore, not all infected birds show a reliable antibody response, potentially resulting in a high frequency of false negative results (França et al 2012).…”

“…державними лабораторіями ветеринарно-санітарної експертизи України досліджено на мікози 82 628 зразків, з них лише 1 671 (2,0 %) зразків були позитивними щодо патогенних грибів, включаючи дерматофіти (Latgé & Chamilos, 2019). З них гриби роду Aspergillus від птахів виділено з 77 зразків (4,1 % від усіх позитивних результатів і 6,1 % від усіх проведених досліджень на аспергільоз), збудників мукормікозу птахів ізольовано з 4 зразках (0,2 % від усіх позитивних результатів мікологічних досліджень) (Savelieff et al, 2018;Talbot et al, 2018;Reed et al, 2020).…”

It has been established that the most common mycoses among poultry are aspergillosis and mucormycosis, which are observed in sporadic cases under conditions of violation of egg incubation technologies, zoohygienic conditions for poultry keeping, and feed storage. Aspergillosis (pneumomycosis, brood pneumonia, mycosis) is an infectious disease that most often affects the respiratory system and, less often, the serous membranes of other organs, namely the liver, intestines, spleen, kidneys, central nervous system, and air cavities of the tubular bones. Aspergillosis affects all species of poultry and wild birds. The disease is more common in young animals in the first days of life. In the studied poultry farms, aspergillosis has a different intensity. The disease can kill 30 to 50 % of all young animals and, in some cases, only a few. This is due to the infection of the fungus in the environment, its pathogenicity, the bird's age, and its resistance. The material for the research was carcasses and aspergillosis-sick birds from Poltava HPE LLC, Poltava Poultry Factory JSC, Poltava Incubator Agricultural Complex, and Poltava district private farms. Statistical indicators from the surveyed farms and micro-sections. It has been established that the causative agent of aspergillosis in chickens and young guinea fowl is mainly the fungus Aspergillus fiimigatus, less often Aspergillus flavus. Sources of infection in the surveyed farms are infected hatching eggs infected with fungal spores and moldy litter. Determining factors contributing to the infection are unsatisfactory conditions for keeping young birds: high humidity and faulty ventilation system. Chickens are more sensitive to aspergillosis than young guinea fowl because, for chickens, the number of detected pathologies in various organs and systems is much higher. The disease in chickens is superacute, acute, and chronic; in young guinea fowl, it is in a mild form (without chronic forms). Clinical signs of avian aspergillosis are not typical, which complicates the lifelong diagnosis of the disease. The results show that raising guinea fowl is a more profitable business because the rate of loss of young is much lower than that of chickens and the rate of sexual maturity for guinea fowl is also higher. Aspergillosis in one-three-day-old chickens is characterized by serous tracheitis, bronchitis, aerosacculitis, and serous fungal pneumonia. Histological examination of the lungs showed swelling of endothelial and alveolar cells, the presence of fungal spores in blood vessels, necrosis, and desquamation of the respiratory epithelium.

“…Thus, this technique, in addition to alternative methods (such as immunohistochemistry, in situ hybridization, and PCR), has been used to determine specific fungal agents present in histopathologic specimens [ 11 , 12 , 13 ]. Furthermore, techniques such as magnetic resonance imaging (MRI) and laser microdissection have provided useful results even in cases of mixed fungal infections [ 11 , 14 ].…”

In the past few years, there has been a spurred tripling in the figures of fungal diseases leading to one of the most alarming rates of extinction ever reported in wild species. Some of these fungal diseases are capable of virulent infections and are now considered emerging diseases due to the extremely high number of cases diagnosed with fungal infections in the last few decades. Most of these mycotic diseases in wildlife are zoonotic, and with the emergence and re-emergence of viral and bacterial zoonotic diseases originating from wildlife, which are causing devastating effects on the human population, it is important to pay attention to these wildlife-borne mycotic diseases with zoonotic capabilities. Several diagnostic techniques such as fungal isolation, gross pathology, histopathology, histochemistry, cytology, immunohistochemistry, radiography, CT, and molecular methods such as PCR or ELISA have been invaluable in the diagnosis of wildlife mycoses. The most important data used in the diagnosis of these wildlife mycoses with a zoonotic potential have been re-emphasized. This will have implications for forestalling future epidemics of these potential zoonotic mycotic diseases originating from wildlife. In conclusion, this review will highlight the etiology, epidemiology, diagnosis, pathogenesis, pathogenicity, pathology, and hematological/serum biochemical findings of five important mycoses found in wild animals.
