“…Disseminated disease occurs in individuals who are severely immunocompromised. 9,11 In dogs and cats, protothecosis is most often caused by P. zopfii, 3,7,10 which produces systemic or cutaneous infections, but infections by P. wickerhamii also occur. 13 Systemic infections affect a number of organs, including the eye, kidney, central nervous system, liver, heart, large intestine, skeletal muscle, myocardium, lymph nodes, thyroid, pancreas, and peritoneum.…”

Abstract. A case of protothecosis is reported in an adult goat with inspiratory dyspnea and stertor. Dermatitis with prominent ulcerated nodules up to 3 cm in diameter was observed in the muzzle at the mucocutaneous junctions of nasal and lip skin, and in the border of the pinna. Histologic lesions were necrotizing pyogranulomatous dermatitis and rhinitis with myriads of walled sporangia, characteristic of Prototheca wickerhamii. This seems to be the first report of protothecosis in a goat.

“…9,11 Most infections occur in individuals who are immunologically compromised by immunosuppressive therapy, acquired immune deficiency syndrome, malnutrition, renal or hepatic disease, cancer, or autoimmune disorders. In contrast, individuals with olecranon bursitis are usually not immunocompromised.…”

“…However, this oomycete is often confused with mucoraceous fungi, because the sparsely septate, hyaline hyphae-like elements of Pythium species resemble the sparsely septate, hyaline hyphae seen in the Mucorales. 26 The use of molecular tools, such as internal transcribed spacer (ITS) or 28S sequencing, is, therefore, needed to confirm the identity of the organism.…”

Imported Pythium insidiosum Keratitis After a Swim in Thailand by a Contact Lens-Wearing Traveler

Abstract.A 30-year-old woman with a history of contact lens wear and exposure to swimming pool water in Thailand presented with a non-responsive, progressive corneal ulcer of the right eye. Confocal microscopy evidenced septate linear branching structures, raising suspicion of fungal keratitis. She was promptly treated with topical antibiotics and both topical and intravenous caspofungin plus voriconazole. Worsening of the clinical picture after 1 month of intensive medical therapy led to a large therapeutic penetrating keratoplasty being performed. Corneal cultures grew a mold-like organism, which was identified by sequencing as Pythium insidiosum, an aquatic oomycete. After 4 years of follow-up, the graft exhibits no infection relapse, but graft transparency has been lost after two rejection episodes. Keratoplasty combined with antifungal treatment may offer a cure to P. insidiosum keratitis, although long-term preservation of corneal transparency is difficult to obtain.

“…However, this information is only partially correct because to date lobomycosis has not been described in freshwater dolphins. What is more worrisome is that this information is beginning to be referenced in other published articles (2). So far, lobomycosis has been confi rmed in 2 species of inshore and estuarine Delphinidae: 1) the common bottlenose dolphin (Tursiops truncatus) from Brazil, the Atlantic coast of the United States, and Europe and 2) the Guiana dolphin (Sotalia guianensis) from the Surinam River estuary (3-8).…”
