Candida parapsilosis and Candida tropicalis infections in an Okhotsk snailfish (Liparis ochotensis)

[摘要] An Okhotsk snailfish (Liparis ochotensis) kept at Nagoya aquarium exhibited sudden death. Microscopically, the fish showed multiple granulomatous foci in the gills, liver and kidney. Multiple yeast-like organisms as well as pseudohyphal elements were observed within granulomatous lesions. Immunohistochemically, the hyphae were negative for both Asperigullus and Mucor spp., and a weak positive for Candida sp. The seminated-PCR product was consistent with Candida parapsilosis and C. tropicalis. This is the first record of disseminated mycotic granulomatous lesion due to C. parapsilosis and C. tropicalis infection in fish.
