    Hello and welcome to Fungal Diseases: Endemic Mycoses. After listening to this lecture, you should be able to name some fungi that cause endemic mycoses. You will be familiar with the pathogenesis and the epidemiology of histoplasmosis and coccidiomycosis. And you'll know which drugs can be used to treat endemic mycoses. Endemic mycoses are diseases caused by fungi that exist in very specific geographical locations, that's why we call them endemic, because the fungi are endemic to certain geographical regions. And the first one I'd like to discuss is histoplasmosis, which is a disease caused by the fungus, Histoplasma capsulatum and a photograph of the organism is shown here. This is a section of tissues containing the yeast form of the organism. And the two organisms we are going to talk about today are dimorphic fungi. They exist filamentous form in the environment, and they transform to the yeast form when they get into a host. Histoplasma is located throughout the central and eastern states of the US; you can find it in parts of Central and South America, parts of Africa, Asia and Australia. It is really geographically limited; you can see there are many parts of the world where it does not occur. The fungus lives in the soil and it particularly likes soil with high nitrogen content and the best way to get high nitrogen, besides adding fertilizer to soil, is to have bird droppings or bat droppings in the soil, because bird and bat excrement has high levels of nitrogen in it. So histoplasma is typically associated with places where we find bird and bat droppings, like caves, where the bats would be, or wherever we keep birds, roosts and coops of various sorts, even old buildings, where pigeons are roosting, you know old building, their...
