title: Electron microscopy, histochemistry, and microbiology of bacterial adhesion in trichomycosis axillaris.
abstract: Study of a case of trichomycosis axillaris by electron microscopy revealed a specific encapsulated Corynebacterium adhering to but not penetrating the hair shaft. External to this were two other biochemically distinctive pleomorphic Corynebacteria shown to be incapable of direct adherence to the hair. All three types were entrapped in a virtually insoluble cement substance, which they elaborate and which is responsible for the grossly visible colonization that is so characteristic of this disease.
