In looking over the field of research there does not seem to be a great amount of work reported on the cause of seborrhea. Various morphologic forms, from Sabouraud's "microbacillus" and Unna's "bottle bacillus" to cocci, such as morococci, diplococci and tetracocci, have been found and studied. Of all the various organisms demonstrated, the coccus forms seem to appear more commonly associated with seborrhea than any of the others. The reports show that these are all forms, from oval to spherical, arranged as diplococci and tetracocci. They seem to occupy a position somewhere between the kingdoms of bacteria and yeasts.

In 1894, Unna found masses of cocci in diplococcus and tetracoccus formation. He cultured these from the hairy scalp. Inoculating dogs with these organisms, he observed reddening of the skin and falling out of hair. He called the organisms morococci. The same experiments were performed with the various other associated
