The treatment DAngelo recommended is INSANE. You cannot tolerate that much of Albendazole. It is a very very toxic drug, and it it will take a huge tall on you. And It is not needed to treat Microsporodium....
Microsporodium as an opportunistic parasite, which means, your immune system in the gut is WEAK, and that is why you got it. Most people who get microsporodum have AIDS level immune system. It is really not a parasite, they are like single cell pores, which you can get through a variety of means, and most normal people never get sick with it.
But If you have D. Fragilis, I would treat that frist Tinidazole for 5 days and FOLLOWED BY Paromo for 10 days. Paromo should start in 6th day. Look these up on drugs.com
And then I would just do 10 days of Albendazole after that. That is it, and dont go anywhere near dentist office, or eat anything that is not thoroughly COOKED. I mean all meats, fish, etc... and salads. for many many months. What are your exact symptoms?
