Hi, Susan. I am sorry to say that I don't have any information to share with you. My only knowledge about histoplasmosis is that I live in Kentucky, where I am aware that it is present in the bird droppings in the soil here. I know of a local man, a farmer, who had his dad visiting him and helping on the farm some years ago. His dad was from another area of the country and had not been exposed to it to developmany resistance. When he returned to his home state, he developed symptoms that his local doctors didn't identify as being histoplasmosis because they were not looking for it. When his son, my friend, mentioned that he had been in Ky and helping on the farm, he was tested and the histoplasmosis was identified and treated. Some years later my friend, the son, came down with symptoms, and was diagnosed with histoplasmosis. He was not treated with any medication and said that it took a while for him to get over it.

If this sounds like it is something that you think would be helpful to you, I would be willing to contact him for the specifics of these cases.
Rosemary
