Exogenous mycosis - Exogenous mycosis

...The pathogenicity of fungi is generally weaker than that of other pathogenic microorganisms such as bacteria and viruses, and many fungi tend to become chronic after infection, but some, such as Cryptococcus neoformans and Histoplasma capsulatum , show acute and severe symptoms and have a high mortality rate. Fungal infections are divided into endogenous mycoses (such infections are called opportunistic infections) in which fungi that are normally present in healthy people become pathogenic for some reason, and exogenous mycoses in which fungi that are not normally present in healthy people infect and develop due to a decrease in resistance. The former include actinomycosis and candidiasis, and the latter include aspergillosis, cryptococcosis, and histoplasmosis. ...

*Some of the terminology that refers to "exogenous fungal infection" is listed below.

…真菌の病原性は一般に，細菌やウイルスなどの他の病原微生物に比べて弱く，感染後慢性化の傾向をたどるものが多いが，クリプトコックスCryptococcus neoformansやヒストプラズマHistoplasma capsulatumのように，急性に激烈な症状を示し死亡率の高いものもある。　真菌症は健康人に常在する菌類が，なんらかの原因で病原性を表し発症する内因性真菌症(このような感染を日和見感染という)と，本来は常在しない菌類が抵抗力の低下によって感染し発症する外因性真菌症に分けられる。前者には放線菌症，カンジダ症があり，後者にはアスペルギルス症，クリプトコックス症，ヒストプラズマ症などがある。…
