Histoplasma genus of fungi in the order Onygenales .[1] Species are known human pathogens producing yeast -like states under pathogenic conditions. They are the causative agents of histoplasmosis in humans and epizootic lymphangitis in horses.[2]
Forms and stages [ edit ]
Histoplasma species have two forms: their environmental form is hyphal with microconidia and tuberculate macroconidia while their pathogenic form is a small intracellular yeast with a narrow neck and no bud with no capsule.[3] mycelial fragments. The dimorphic mold-yeast transforms and enters host macrophages and proliferates within them. Infections are most often seen in immunodeficient individuals.[4]
Species are mainly found in the Ohio and Mississippi River Valleys in the United States (H.ohiense H. mississippiense H. capsulatum H. suramericanum H. duboisii [5] [6]
