Aspergillus disease (aspergillus blight)

Japanese: こうじかび病(麴黴病) - こうじかびびょう(英語表記)aspergillus disease
Aspergillus disease (aspergillus blight)
A general term for diseases caused by the parasitization of insects by filamentous fungi of the Aspergillus genus. It is a particularly important disease in silkworms, and the pathogens include A. flavus , A. oryzae , A. tamari , and A. ochraceus . Silkworms are susceptible to infection at the young stage, and sudden death occurs when the disease develops. As silkworms grow older, their resistance increases, but they become susceptible to infection again at the mature stage, and the disease develops and leads to death in the larval or pupa stage inside the cocoon. When conidia attached to the skin of the larvae germinate, the hyphae penetrate the skin and grow and extend inside the body, invading parts of each tissue.

Japanese:
昆虫に子囊菌類コウジカビ属Aspergillusの糸状菌が寄生して起こる病気の総称。とくにカイコで重要な病気であり,病原菌としてA.flavus,A.oryzae,A.tamari,A.ochraceusなどがある。カイコでは稚蚕期に感染しやすく発病すると急死する。齢が進むにしたがってカイコの抵抗力は増大するが,熟蚕期に再び感染しやすくなり,繭の中で幼虫あるいはさなぎの形で発病して死に至る。幼虫の皮膚に付着した分生子が発芽すると菌糸は皮膚を貫通し,体内に達すると生育伸長して各組織の一部を侵害する。
