“…Mycotic infections in African grey parrots including pulmonary aspergillosis by Aspergillus fumigatus (Oca et al, 2022), cryptococcosis (Schunk et al, 2017), mucormycosis (Desmidt et al, 1998, and penicillosis (Lanteri et al, 2011) have been reported, so the gray parrot is thought to be highly susceptible to mycotic infections (Arné et al, 2021). Clinical signs of avian aspergillosis may be nonspecific, with hyperthermia, weight loss, anorexia, and polydipsia, and may be directly related to the affected systems, such as coryza, unproductive cough, wheezing on auscultation, and dyspnea in cases of respiratory infections (Arné et al, 2021).…”

Aspergillosis is a fungal disease with high morbidity and mortality in wild and exotic bird species. The aim of this report is to describe a case of acute aspergillosis caused by Aspergillus fumigatus in a young African grey parrot (Psittacus erithacus). A three-month-old male African grey parrot from a commercial breeding site presented serous nasal discharge, inappetence, and wheezing on pulmonary auscultation. The parrot died three days after the onset of clinical signs. Postmortem evaluation demonstrated multiple smooth gray plaques in air sacs and left lung with dark red areas and adhesions to the ribs. Microscopically, there were intralesional hyphae and conidiophores in the lungs, air sacs, and ribs, which were associated with pneumonia, airsacculitis, and osteomyelitis, respectively. DNA samples were extracted from paraffinized tissues and subjected to PCR targeting the ITS-2 region, followed by sequencing, which yielded a sequence with 100% coverage and 100% identity to Aspergillus fumigatus sequences. Although A. fumigatus infection is quite common in birds, a particular aspect of interest in this case was the finding of conidiophores in the bone marrow, which may occur in birds due to air circulation through pneumatic bones.

“…Subsequently, it was documented that bamboo rats and the soil from their burrows were important enzootic and environmental (natural) reservoirs of P. marneffei [ 148 , 149 , 150 ]. However, penicilliosis is still rare in animals [ 151 ].…”

“…The histopathology of a captive-born Congo African grey parrot with penicilliosis revealed mature multifocal granulomas, typically caseous, with necrotic centers where several septate hyphae, as well as macrophages and giant cells, were detected in lung, liver, and kidney samples. The Grocott staining revealed black septate fungal hyphae with conidia [ 151 ].…”

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.
