Resumo
Background: Aspergillus spp. are dimorphic fungus widely distributed in the environment, including in soil, dust and decaying vegetation. Clinical signs of aspergillosis in horses including rhinitis, pneumonia, guttural pouch mycosis, keratomycosis, endometritis, abortions and systemic involvement. In addition, horses with a history of enterocolitis may be predisposed to pulmonary or systemic mycotic infection. However, reports about systemic aspergillosis in horses are restricted to infections by A. fumigatus and A. niger. There have been no reports of systemic infection caused by A. flavus in horses or in other domestic species. Thus, the objective of this work was to describe the epidemiological, clinical and pathological aspects of systemic infection by Aspergillus flavus in a mare.Case: A 3-year-old pregnant mare of the Manga Larga, had signs of colic two days prior to admission after grazing in a landfill area to which it had free access. The owner observed remains of plastic bags in the stool. Clinically, there was dehydration, apathy, ocular mucosal congestion, oral cyanosis, reluctance to move, diarrhea, fever, drooling and tachypnea. Due to its clinical condition, the animal was referred to the surgical center for exploratory laparotomy, where compaction in the colon and cecum was verified. Enterotomy and enterolith removal were performed in the small colon region. The mare died after eight days of hospitalization, and necropsy was performed. Macroscopically disseminated lesions were observed in the small colon, stomach, kidneys, lungs, heart and brain. Fragments of tissues from organs in the abdominal and thoracic cavities, as well as from the central nervous system, were collected, fixed in 10% buffered formalin solution, and subsequently routinely processed and stained with hematoxylin and eosin and special histochemical stains to visualize the infectious agent and its morphological characteristics.[...](AU)
