“…Furthermore, A . pullulans has been associated with cutaneous and systemic infections in immunosuppressed humans [ 76 – 80 ] and occasionally ascribed to cutaneous infections in few animal species [ 81 ]. In the present case, the histomorphological features of the fungus and PCR analysis supported the diagnosis of ruminal mycosis by A .…”

This retrospective study describes the biological and epidemiological aspects, gross and microscopical findings, and most likely causes of death (CD) in two species of Neotropical deer in Brazil. The animals were collected between 1995 and 2015 and represented 75 marsh deer (MD) and 136 brown brocket deer (BBD). Summarized, pneumonia was diagnosed microscopically in 48 MD and 52 BBD; 76 deer suffered trauma, involving dog attack (14 BBD) and vehicle-collision (14 BBD). Pulmonary edema (50 MD; 55 BBD) and congestion (57 MD; 78 BBD) were the most common findings for both species. Additionally, we diagnosed ruminal and myocardial mycosis in MD and BBD, respectively; ovarian dysgerminoma and pancreatic trematodiasis in BBD; and lesions suggestive of malignant catarrhal fever and orbiviral hemorrhagic disease in both species. The main CD in MD was: respiratory (41/75), alimentary, nutritional, trauma and euthanasia (3/75 each). Correspondingly, in BBD were: trauma (34/131), respiratory (30/131) and euthanasia (9/131). Respiratory disease was often defined by pulmonary edema and pneumonia. We provide evidence that respiratory disease, mainly pneumonia, is a critical pathological process in these Neotropical deer species. Although no etiological agents were identified, there is evidence of bacterial and viral involvement. Our results show trauma, mainly anthropogenic, as a common ailment in BBD. We propose to prioritize respiratory disease in future research focused on South American deer health aspects. We believe anthropogenic trauma may be a primary threat for populations of BBD.

“…Its isolation from clinical specimens is generally considered as a contaminant. Of the 14 species of Aureobasidium known to date, A. pullulans is the best known to clinical mycologists, since it has been indicated as a rare etiologic agent of pheohyphomycosis, keratomycosis, septicemia, peritoneal sepsis, and dermatological infections (6,9,11,12,13,14,15,16).…”

We report on a rare case of disseminated nosocomial fungal infection due to Aureobasidium pullulans var. melanigenum in a severely traumatized patient. Repeated blood and urine cultures yielded multicellular filamentous hyphal structures of varying size accompanied by budding yeast-like-cells of ellipsoidal morphology. The patient became asymptomatic after fluconazole therapy. CASE REPORTThe patient, a 28-year-old male, was admitted to the intensive care unit of the Ospedali Riuniti of Reggio Calabria, Reggio Calabria, Italy, following multiple traumas due to a road accident. The patient suffered a head trauma and had a Glasgow coma scale rating of III-IV. After initial treatment with standard life support measures to stabilize hemodynamic and respiratory parameters, the patient underwent a total-body computed tomography scan, which showed diffuse cerebral edema, hemoperitoneum, multiple fractures of the left femur and tibia, a suspected pelvic fracture, and multiple ruptures of the liver's right lobe, which made immediate surgery mandatory. After surgery, the patient underwent mechanical ventilation and prolonged total parenteral nutrition.Following the isolation of a methicillin-resistant strain of Staphylococcus epidermidis from a blood culture (BCB-Slide system; Roche Products Pty. Ltd.) antibiotic therapy was started, with teicoplanin at 800 mg/day plus vancomycin at 2 g/day, divided into two doses daily. Four days later, following the onset of dyspnea and fever (37.5 to 38°C), a pulmonary infection was suspected. Laboratory data included a total leukocyte count of 10.7 ϫ 10 9 /liter with 70% neutrophils, 26% lymphocytes, and 4% monocytes. Microbiological examination of a bronchial aspirate showed the presence of Acinetobacter anitratus var. anitratus. Antibiotic therapy was therefore changed, replacing teicoplanin with ceftazidime pentahydrate at 4 g/day. After an initial decrease in body temperature lasting 3 days, fever increased again to 40°C. Therefore, a new blood culture was carried out, leading to the isolation of Pseudomonas aeruginosa. On the basis of antibiogram results, antibiotic treatment was changed again, with aztreonam at 6 g/day plus tobramycin at 300 mg/day, divided into three doses daily. Six days later, since fever was stable at around 38°C and the patient's condition was not improving, new cultures from blood and urine were made. After 72 h of incubation, the blood culture became diffusely turbid and several smooth and mucoid colonies appeared on agar growth media (chocolate agar and malt agar) enclosed in the BCB-Slide Roche system (Fig. 1). The urine culture, in contrast, was negative.Microscopic examination of fungal cultures revealed multicellular filamentous hyphal structures of varying size accompanied by budding ellipsoidal yeast-like cells, both in the blood culture and in the colonies growing on agar media. These fungal isolates were subsequently classified as Aureobasidium pullulans.Immediately before starting antifungal therapy, a new set of blood and urine cultures and a cu...

“…There is a prior report of A. benhamiae or T. mentagrophytes in a family of NAP in a Japanese zoo, and T. mentagrophytes was isolated from a South African porcupine, though it is important to note that the South African porcupine is not a closely related species to NAP [32,39]. There is a single case report outlining cutaneous mycosis in an individual NAP due to infection with the yeast-like Aureobasidium pullulans [40]. A very recent paper reports a more limited infection with the geophilic (soil-associated) dermatophyte Microsporum gypseum in a zoo-housed porcupine [14].…”

Atypical Dermatophytosis in 12 North American Porcupines (Erethizon dorsatum) from the Northeastern United States 2010–2017

et al. 2019

Twelve wild North American porcupines (Erethizon dorsatum) out of a total of 44 of this species examined in an 8-year period were diagnosed with dermatopathies while being cared for at two wildlife rehabilitation clinics. Biopsy and necropsy were performed on seven and five animals, respectively. Atypical dermatophytosis was diagnosed in all cases. Lesions consisted of diffuse severe epidermal hyperkeratosis and mild hyperplasia with mild lymphoplasmacytic dermatitis and no folliculitis. Dermatophytes were noted histologically as hyphae and spores in hair shafts, and follicular and epidermal keratin. Trichophyton sp. was grown in 5/6 animals where culture was performed, with a molecular diagnosis of Arthroderma benhamiae/Trichophyton mentagrophytes in these five cases. Metagenomic analysis of formalin-fixed paraffin-embedded tissue samples from three cases identified fungi from 17 orders in phyla Basidiomycota and Ascomycota. Alteration of therapy from ketaconazole, which was unsuccessful in four out of five early cases, to terbinafine or nitraconazole led to the resolution of disease and recovery to release in four subsequent animals. In all, six animals were euthanized or died due to dermatopathy, no cases resolved spontaneously, and six cases were resolved with therapy. The work we present demonstrates an atypical lesion and anatomical distribution due to dermatophytosis in a series of free-ranging wild porcupines and the successful development of novel techniques for extracting and sequencing nucleic acids from fungus in archival formalin-fixed paraffin-embedded animal tissue.
