“…Although not a mycotic infection and thus beyond the scope of this review, it is noteworthy that Aspergillus spp. may contaminate hatcheries causing significant economic damages ( Hamet et al, 1991 ). Fungi infecting birds must be able to grow at the relatively high body temperature of these animals that may surpass 40°C ( Prinzinger et al, 1991 ).…”

The genus Aspergillus is composed of more than 300 species, a fraction of which are involved in animal or human infections mostly following environmental exposure. Various risk factors (i.e., immunosuppression, tuberculosis) have been recognized for human whereas for veterinary infections, unhygienic management, trauma, anatomical conformation of the skull, or suspected immunological deficiencies have been suggested. In animals, aspergillosis is mostly sporadic but in some circumstance such as infections on poultry farms may involve the whole flock. Since the high prevalence of immunosuppression in human patients has not been mirrored in veterinary medicine, and although to the best of our knowledge, no comprehensive data on the prevalence of aspergillosis in animals has been published, their epidemiology has not changed during the last decades. The impact of these infections may be economic or if they are incurable, sentimental. The objective of the first part is to describe the diagnosis of the main clinical entities caused by Aspergillus spp. in animals. It includes disseminated canine aspergillosis, canine and feline sino-nasal and sino-orbital aspergillosis, guttural pouch mycosis in horses, mycotic abortion in cattle, mycotic keratitis in horses, and avian aspergillosis. When pathogenesis and clinical aspects are relevant for diagnosis—they will be addressed as well. The second part deals with human aspergillosis, which is a multifaceted disease, manifested in a spectrum of clinical entities affecting one or more organs. Diagnosis is based on the clinical manifestation, supported and confirmed by laboratory means, involving the classical approach of demonstrating the etiological agent in the clinical specimens and in culture. Noncultural methods, such as antigen detection and/or molecular assays to detect fungal nucleic acids or protein profiles, are used as well. The isolation and identification of the fungus allows the determination of its susceptibility to antifungal drugs. Thus, antifungal susceptibility testing maybe considered as part of the diagnostic process, which is of relevance for management of the infection. In this review article, the part dealing with diagnostic aspects of aspergillosis in humans concentrates on susceptibility testing of Aspergillus spp. to antifungal drugs and drug combinations. The technologies and methods of susceptibility testing are described and evaluated.

The present study was carried out to evaluate the pathological effects of aspergillosis caused by Aspergillus Spp. in commercial broiler chickens. In this study, we discussed few outbreaks of Aspergillus infection of chicks a week aftter hatching in broiler farms of Duhok-Kurdistan region of Iraq during the period from February to May 2015 on the basis of clinical signs, post-mortem, histopathological and cultural findings. The main clinical signs of the disease in the infected flock included a 3-day onset of labored breathing and neurologic disorders displayed by incoordination, torticollis, and paralysis. Other clinical features included depression, ruffled feathers and gasping. Gross lesions were represented by cheesy granular materials in the air sacs, lungs, and trachea. Histopathology revealed fungal hyphae in sectioned lung tissue. Aspergillus was isolated by culturing in Sabouraud's dextrose agar from the lesions. The present study deals with the incidence of acute aspergillosis in broiler chicks from Duhok, Kurdistan-Iraq.

Hygienic measures in abattoir positively reflect on quality of meat. So, characterization of Salmonella species isolated from the environment of abattoirs as well as meat of slaughtered cattle was carried out in 5 municipal slaughterhouses located in different provinces, Egypt. A total of 300 samples were collected including slaughtered meat, water, and air samples beside swabs from floor, wall, and workers hand (50 samples/each). It was observed that the highest isolation rate was obtained from hand swabs (8%) followed by meat samples (6%) then floor and wall swabs, and water samples (4% for each) while Salmonella could not be isolated from air samples. Moreover, serotyping of the recovered isolates (n=13) clarified the presence of various serotypes including S. Enteritidis, S. Typhimurium, S. Heidelberg, and S. Virchow with different rates. In addition, PCR was employed successfully for confirmation of the obtained isolates through detection of invA gene of Salmonella strains. Antibiogram pattern of the recovered Salmonella isolates (n=13) clarified that isolates were resistant to Amikacin and Ciprofloxacin (76.9%) then Vancomycin (53.8%), while it was found that 92.3% of isolates were sensitive to Gentamycin and Linezolid. Based on the recorded result, isolation of Salmonella from abattoirs environment as well as meat constitutes public hazard for consumers.
