Fungal Infections

Unusual presentation and urinary tract obstruction due to disseminated intra-abdominal eumycetomas caused by Curvularia species in a dog

“…The ante-mortem and post mortem findings confirm the intra-abdominal masses to be black-grained eumycetomas due to Curvularia species [[1], [2], [3], [4], [5], [6]]. The similar histological appearance between the eumycetomas examined in this investigation and the one removed from the dog three years prior, suggests that they are likely to be caused by the same fungus.…”

“…Eumycetomas in dogs typically arise from traumatic inoculation of soil contaminated with mould into the skin or subcutaneous tissue [[1], [2], [3]]. These are characterised by painless tumefaction, development of draining sinuses several months post-inoculation, and macroscopic pigmented grains containing fungal hyphae in the exudate [[1], [2], [3]]. Treatment involves surgical excision and long-term anti-fungal therapy, but successful elimination of the fungus is rare [[4], [5], [6]].…”

“…Apart from Curvularia , several other species of mould from the genera of Aspergillus , Cladophialophora, Madurella, Penicillium, and Scedosporium , have been reported to cause eumycetomas in dogs [[4], [5], [6]]. Fungi of the Curvularia species are typically found in arid areas similar to Alice Springs where the dog lived [[1], [2], [3]]. They are ubiquitous environmental soil saprophytes, that get picked up through inoculation of the skin or subcutaneous tissues of the host via traumatic penetration of contaminated material [[1], [2], [3]].…”

“…Eumycetomas are chronic pyogranulomatous lesions caused by moulds, frequently reported in humans living in tropical and subtropical environments (e.g. Madura Foot) but rarely in dogs [[1], [2], [3], [4], [5], [6]]. Usually restricted to subcutaneous tissues, there have been only two reports of cases involving intra-abdominal lesions in dogs [[4], [5], [6]].…”

Afectación intestinal por un hongo dematiáceo

“…En cuanto al manejo terapéutico, la mayor parte de las infecciones por hongos dematiáceos requieren de tratamiento quirúrgico y médico con antifúngicos como anfotericina B o itraconazol, siendo este último el que ha mostrado mayor actividad in vitro 6 . En este caso, dado que el paciente no presentaba afectación sistémica, únicamente requirió escisión local del micetoma.…”
