Abstract
Fungal infections have a key effect on the commercial poultry production and welfare. Infections caused by fungi and their food contaminants are zoonotic and influence food safety. Eggs and cooked meats remain major public health concerns. Therefore, this research is aimed at examining the pathology and understanding the epidemiology of fungal infection in layer chicken flocks. The study was carried out on twenty-layer flocks from Kafrelsheikh Governorate, Egypt, from January 2019 to December 2020. In total, 600 samples were collected from 100 healthy and diseased layer chickens from different organs (skin, liver, lung, kidney, spleen, and ovary). In this work, we present the clinical and pathological characteristics of some fungal pathogens (Aspergillus spp. and Fusarium spp.) in layer chicken flocks, as they are responsible for reducing the egg production. In total, 19 fungal strains were isolated from individual chickens, and these were analysed to determine the fungal species. The total proportion of fungal infections at the farm level was (3/20) 15%. The main clinical signs were emaciation and mortalities that reached
. We report the first isolation of Aspergillus piperis and Fusarium species from the ovary of poultry, which is the main reason for egg retention and multiple numerous nodules of occasional caseating centers in layer ovaries. The histopathological findings of Aspergillus infection are indicated by the presence of branched hyphae that tend to be numerous and progressive. Furthermore, we found spherules with multiple endospores of Fusarium spp. in the ovaries. Morphological and molecular identification and analysis were performed to confirm the etiological agents.

Nourani L, Aliabadian M, Mirshamsi O, Dinparast Djadid N. Prevalence of co-infection and genetic diversity of avian haemosporidian parasites in two rehabilitation facilities in Iran: implications for the conservation of captive raptors. BMC Ecol Evol 2022; 22:114. [PMID: 36209068 PMCID: PMC9547439 DOI: 10.1186/s12862-022-02068-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 09/23/2022] [Indexed: 11/06/2022] Open
Abstract
Background Various haemosporidian parasites infect raptors, especially captive hosts who may be more exposed. Diagnosis of threatening factors such as infectious diseases indirectly has a significant role in protecting endangered or threatened species that may boost the mortality or extinction resulting from declined reproduction. Few investigations have been performed in captive hosts to detect the prevalence of haemosporidian parasites and define genetic diversity in west Asia. For the first time, the current study was designed to determine the prevalence and genetic diversity of haemosporidian parasites in captive raptors by molecular methods in two rehabilitation facilities in North and North-east Iran and to define phylogenetic relationships of detected lineages circulating in raptors. Results Molecular characterization of the haemosporidian parasite was accomplished by PCR-based method and DNA sequencing in 62 captive raptors. The overall prevalence was ~ 36% with higher infection of Haemoproteus spp. than Leucocytozoon spp. Plasmodium infection was not detected in any host. Results showed that 22 individuals (of 10 species) were infected with unique lineages. Genus Haemoproteus was detected in 26.66% of examined individuals (of eight species) and Leucocytozoon was found in 10% of individuals (of four species). The molecular analysis could detect ten lineages (nine Haemoproteus spp. and one Leucocytozoon spp.) which were categorizes as new and six lineages which have been previously detected in the other investigations. Conclusions The Bayesian phylogenetic analysis derived from obtained data in the present study and published lineages in previous investigations indicated the probable host specificity of Haemoproteus and Leucocytozoon parasites in several sub-clades at hosts’ order and genus level. As monitoring the parasite loads of captive birds when admitted reduce the risk of infecting hosts in captivity at those locations, we designed this study to determine infection prevalence and genetic diversity of blood parasites in raptors examined in Iran. These results allow mapping of haemosporidian distribution and shed light on the depth of their diversity in Iran to protect species by identification of risk in rehabilitation facilities.

Important Mycoses of Wildlife: Emphasis on Etiology, Epidemiology, Diagnosis, and Pathology—A Review: PART 1. Animals (Basel) 2022; 12:ani12151874. [PMID: 35892524 PMCID: PMC9331704 DOI: 10.3390/ani12151874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 07/19/2022] [Accepted: 07/20/2022] [Indexed: 11/17/2022] Open
Abstract
Simple Summary The number of wild animals is steadily declining globally, so the early diagnosis and proper treatment of emerging diseases are vital. Fungal diseases are commonly encountered in practice and have a high zoonotic potential. This article describes aspergillosis, candidiasis, histoplasmosis, cryptococcosis, and penicilliosis, and is only the first part of a detailed review. The laboratory methods (fungal isolation, gross pathology, histopathology, histochemistry, cytology, immunohistochemistry, radiography, CT, PCR, or ELISA) used in the diagnosis and the clinical details that provide a complete view of the mycoses are presented. Abstract 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.

Abstract
The ubiquitous fungi belonging to the genus Aspergillus are able to proliferate in a large number of environments on organic substrates. The spores of these opportunistic pathogens, when inhaled, can cause serious and often fatal infections in a wide variety of captive and free-roaming wild birds. The relative importance of innate immunity and the level of exposure in the development of the disease can vary considerably between avian species and epidemiological situations. Given the low efficacy of therapeutic treatments, it is essential that breeders or avian practitioners know the conditions that favor the emergence of Aspergillosis in order to put adequate preventive measures in place.

Abstract
Aspergillosis causes high morbidity and mortality in avian species. The main goal of this study was to use molecular techniques to identify Aspergillus species collected from different avian species with aspergillosis. A subsample of those isolates was also screened for resistance to itraconazole. Over a 2-year period, clinical samples were recovered from 44 birds with clinical signs of the disease, clinical pathology results suspicious of aspergillosis, or from birds that died from Aspergillus spp. infection. Environmental sampling was also performed in seabird rehabilitation centers and natural seabird environments. Seventy-seven isolates (43 clinical and 34 environmental) were identified as Aspergillus fumigatus sensu stricto. No cryptic species from the Fumigati section were detected. Two environmental isolates were identified as Aspergillus nidulans var. dentatus and Aspergillus spinulosporus. None of the Aspergillus isolates tested were resistant to itraconazole. Our study emphasizes the dominant association of Aspergillus fumigatus sensu stricto in avian mycoses and shows the lack of itraconazole resistance in the studied isolates.

Abstract
Aspergillosis in falcons may be associated with high mortality and difficulties in clinical and laboratory diagnosis. We previously cloned an immunogenic protein, Afmp1p, in Aspergillus fumigatus and showed that anti-Afmp1p antibodies were present in human patients with A. fumigatus infections. In this study, we hypothesise that a similar Afmp1p-based enzyme-linked immunosorbent assay (ELISA) could be applied to serodiagnose falcon aspergillosis. A specific polyclonal antibody was first generated to detect falcon serum IgY. Horseradish peroxidase-conjugate of this antibody was then used to measure anti-Afmp1p antibodies in sera collected from falcons experimentally infected with A. fumigatus, and the performance of the Afmp1p-based ELISA was evaluated using sera from healthy falcons and falcons with documented A. fumigatus infections. All four experimentally infected falcons developed culture- and histology-proven invasive aspergillosis. Anti-Afmp1p antibodies were detected in their sera. For the Afmp1p-based ELISA, the mean ± SD OD450 nm using sera from 129 healthy falcons was 0.186 ± 0.073. Receiver operating characteristics curve analysis showed an absorbance cut-off value of 0.407. One negative serum gave an absorbance outside the normal range, giving a specificity of 99.2%. For the 12 sera from falcons with confirmed aspergillosis, nine gave absorbance values ≥ cut-off, giving a sensitivity of 75%. The Afmp1p-based ELISA is useful for serodiagnosis of falcons with aspergillosis.

Abstract
Aspergillosis is a common and life-threatening respiratory disease in raptors with acute and chronic courses. Among raptors, gyrfalcons (Falco rusticolus) and their hybrids are often declared to be highly susceptible with juvenile individuals being the most susceptible. However, species- and age-specific experimental studies are lacking and minimal infective doses (IDs) for Aspergillus spp. conidia are unknown.Therefore, 8-week-old, healthy gyr-hybrid falcons (F. rusticolus X F. cherrug) (N = 18) were experimentally infected with Aspergillus fumigatus using a single intratracheal inoculation with varying dosages of conidia (102 to 107 conidia). Over 28 days, clinical signs were monitored as well as haematological and serological parameters. Following euthanasia, necropsy, histopathology, bacteriology, and mycology were performed. Re-isolated fungi were compared to the inoculum using microsatellite length polymorphisms. During the trial, clinical signs and dyspnoea correlated significantly with the ID. Necropsy revealed fungal lesions in the upper and lower airways of 10/18 inoculated falcons, but not in the control birds. In 9/18 inoculated falcons, fungal granulomas were confirmed in histopathology and A. fumigatus was re-isolated from these granulomas. Except one nasal isolate all re-isolated fungal strains were identical to the inoculum strain. Based on mycology and histopathology a minimal ID of 50% was calculated to be MID50% (±S.E.) = 104.52±0.67 for a single tracheal inoculation of A. fumigatus conidia. This study demonstrates for the first time that a single exposure is able to cause acute aspergillosis in juvenile falcons.

Abstract
Resumo: Este trabalho descreve um caso de infecção mista por pox vírus e Aspergillus fumigatus em Bubo virginianus (coruja jacurutu). A ave, um macho adulto, foi encaminhada ao Núcleo de Reabilitação da Fauna Silvestre do Instituto de Biologia da Universidade Federal de Pelotas (NURFS/CETAS/UFPEL). Apresentava bom estado corporal, estava ativa, porém com incapacidade de voo. Após três dias apresentou lesões crostosas e de aspecto verrucoso na superfície dorsal das patas. Havia, também, nódulos de mesmo aspecto na pálpebra esquerda e na cera. A ave morreu após 15 dias de sua chegada ao NURFS e foi necropsiada no Laboratório Regional de Diagnóstico da Faculdade de Veterinária da Universidade Federal de Pelotas (LRD/UFPel). Histologicamente, as lesões verrucosas caracterizavam-se por hiperplasia do epitélio e nas células das camadas basal, espinhosa, granular e córnea havia corpúsculos de inclusão intracitoplasmáticos do tipo Bollinger. Na microscopia eletrônica foram visualizadas partículas virais características de pox vírus, incluindo Bubo virginianus como um hospedeiro do vírus. Havia, ainda, infiltrado inflamatório de células mononucleares e focos de colônias bacterianas na derme. Nos pulmões havia congestão e presença de granulomas com hifas fúngicas, que pela técnica de Grocott, apresentaram ramificação dicotômica compatível com Aspergillus spp., identificado na cultura como A. fumigatus. O diagnóstico de infecção por avipoxvirus pode contribuir para estudos relacionados com a ocorrência desta doença nas populações de vida livre e como informação auxiliar para o manejo e conservação desta espécie. Sugere-se, ainda, a inclusão do uso de raios-X nos protocolos de centros de reabilitação como o diagnostico de aspergilose em aves rapinantes com bom estado corporal, porém incapazes de voar.

Abstract
Of the many important avian wildlife diseases, aspergillosis, West Nile virus, avipoxvirus, Wellfleet Bay virus, avian influenza, and inclusion body disease of cranes are covered in this article. Wellfleet Bay virus, first identified in 2010, is considered an emerging disease. Avian influenza and West Nile virus have recently been in the public eye because of their zoonotic potential and links to wildlife. Several diseases labeled as reemerging are included because of recent outbreaks or, more importantly, recent research in areas such as genomics, which shed light on the mechanisms whereby these adaptable, persistent pathogens continue to spread and thrive.

Abstract
Aspergillosis is frequently reported in parrots, falcons and other birds held in captivity. Inhalation is the main route of infection for Aspergillus fumigatus, resulting in both acute and chronic disease conditions. Itraconazole (ITRA) is an antifungal commonly used in birds, but administration requires repeated oral dosing and the safety margin is narrow. We describe lung tissue and serum pharmacokinetics of a nanoparticulate ITRA suspension administered to Japanese quail by aerosol exposure. Aerosolized ITRA (1 and 10% suspension) administered over 30 min did not induce adverse clinical reactions in quail upon single or 5-day repeated doses. High lung concentrations, well above the inhibitory levels for A. fumigatus, of 4.14 ± 0.19 μg/g and 27.5 ± 4.58 μg/g (mean ± SEM, n = 3), were achieved following single-dose inhalation of 1% and 10% suspension, respectively. Upon multiple dose administration of 10% suspension, mean lung concentrations reached 104.9 ± 10.1 μg/g. Drug clearance from the lungs was slow with terminal half-lives of 19.7 h and 35.8 h following inhalation of 1% and 10% suspension, respectively. Data suggest that lung clearance is solubility driven. Lung concentrations of hydroxy-itraconazole reached 1-2% of the ITRA lung tissue concentration indicating metabolism in lung tissue. Steady, but low, serum concentrations of ITRA could be measured after multiple dose administration, reaching less than 0.1% of the lung tissue concentration. This formulation may represent a novel, easy to administer treatment modality for fungal lung infection, preventing high systemic exposure. It may also be useful as metaphylaxis to prevent the outbreak of aspergillosis in colonized animals.

Abstract
Although aspergillosis is one of the most common diseases in captive birds, the pathogenesis of avian aspergillosis is poorly known. We studied the role of avian respiratory macrophages as a first line of defense against avian aspergillosis. The phagocytic and killing capacities of avian respiratory macrophages were evaluated using pigeon respiratory macrophages that were inoculated with Aspergillus fumigatus conidia. On average, 25% of macrophage-associated conidia were phagocytosed after one hour. Sixteen percents of these cell-associated conidia were killed after 4 h and conidial germination was inhibited in more than 95% of the conidia. A. fumigatus conidia were shown to be cytotoxic to the macrophages. Intracellularly germinating conidia were located free in the cytoplasm of necrotic cells, as shown using transmission electron microscopy. These results suggest that avian respiratory macrophages may prevent early establishment of infection, unless the number of A. fumigatus conidia exceeds the macrophage killing capacity, leading to intracellular germination and colonization of the respiratory tract.

Abstract
In vivo modelling of aspergillosis in birds allows the evaluation of control measures and the study of host-pathogen interactions. In this study the impact of the use of different inoculation routes and immunosuppression on the course of an infection with Aspergillus fumigatus in racing pigeons (Columba livia domestica) was examined. A. fumigatus conidia were inoculated in the thoracic air sac, lung or trachea in immunocompetent or immunosuppressed pigeon squabs. Immunosuppression was induced by three dexamethasone injections before inoculation. Mortality in the A. fumigatus-inoculated groups varied between 1/4 and 4/4. The highest and more acute mortality was seen in immunocompetent pigeons inoculated in the thoracic air sac and in pigeons inoculated in the thoracic air sac or lung after immunosuppression. Pigeons inoculated in the lung or inoculated intratracheally after immunosuppression developed an aspergillosis infection with a slower course of disease and more prominent clinical symptoms. Using microsatellite length polymorphism, it was confirmed that all mycoses were caused by the inoculated strain except for one isolate in a dexamethasone-treated pigeon. In conclusion, inoculation in the lung is selected as the preferred model for chronic aspergillosis in pigeons, and inoculation in the thoracic air sac as the preferred model for acute aspergillosis. The use of immunosuppressed birds seems to be contra-indicated due to the risk of opportunistic infections.
