“…15 These lesions may then extend into the anterior segment but rarely progress into the posterior part of the eye. 3 In this case, the fungal keratitis likely was a result of trauma because of the acute onset and unilateral nature. The uveitis may have been caused by reflex or fungal endophthalmitis, which then led to the cataract and posterior synechia appreciated in the OS.…”

“…Most reports are from gallinaceous species that have been managed in a production setting. [2][3][4] The only fungal organism reported previously as a cause of keratitis in ducks is Candida albicans. 5 To our knowledge, aspergillosis has not been reported as a cause of keratitis in ducks.…”

“…Because of the infrequency with which mycotic keratitis has been reported in avian species, no correlation can be made to season and incidence rate; however, it has been speculated that development of disease in poultry is related to factors in the environment in production settings, such as fumes and ammonia. [2][3][4] Fungi are considered to be opportunistic pathogens and part of the normal ocular surface flora in all species. 7 In a report of bacterial and fungal flora found in healthy eyes of birds of prey, fungal growth was found in 2.3% of sampled eyes; the low prevalence was thought to be transitory and resulting from environmental exposure.…”

A 1.5-year-old, intact female khaki Campbell duck (Anas platyrhynchos domesticus) was evaluated for lethargy and a swollen left eye (OS). Mucoid discharge, chemosis, and conjunctival hyperemia with trace aqueous flare, indicating anterior uveitis, in the anterior chamber were evident on ophthalmic examination. There was no fluorescein stain uptake by the cornea. Initial topical antibiotic therapy and systemic anti-inflammatory treatments were unsuccessful, and the lesion progressed to a diffuse, yellow-white plaque, which covered 90%-95% of the cornea 4 days later. There was moderate blepharospasm, mild blepharedema, and epiphora OS. The mobility of the nictitating membrane was impaired because of the presence of the plaque over the cornea. Cytologic examination of a corneal scraping revealed fungal hyphae, and aerobic culture confirmed Aspergillus species. Treatment with topical voriconazole (1 drop OS q4h-q6h) was initiated and was switched to oral voriconazole (20 mg/kg PO q12h) 6 days after initiating treatment. The ocular disease improved during the antifungal treatment period. Eighty-four days after initial presentation (9 days after discontinuation of treatment), there was no clinical evidence of mycotic keratitis on ophthalmic examination.

“…There is little information available about eumycotic mycetoma formation related to Scedosporium species. Scedosporium infection in other animal species has been documented including cats, horses, layer pullets, cows, and humans . In dogs, Scedosporium species have been previously documented causing keratomycosis, discospondylitis, osteomyelitis, disseminated disease, and rhinitis .…”

A 5-year-old, spayed female, Basset Hound was referred for evaluation of a urinary bladder mass. Ultrasonographic images revealed a large, inhomogeneous, hypoechoic mass associated with the dorsal wall of the neck of the urinary bladder and left ureter. Partial cystectomy and left ureteral reimplantation were performed. Histopathology showed a severe inflammatory mass lesion forming multiple granulomas. A DNA sequencing test revealed Scedosporium apiospermum as the causative agent. Susceptibility tests on the isolated strain indicated susceptibility to voriconazole. To the authors' knowledge, this is the first report describing S. apiospermum as a cause of granulomas involving the canine ureterovesicular junction.
