Bacteriology; Pathogenic bacteria. 2 so SPECIFIC MICRO-ORGANISMS specifically identical with, Achorion schoenleinii. The exact relationships of the parasites are not very fully settled as yet. Microsporon Audouini.—This mold is found growing in the hair-shaft in alopecia areata. If the ha,ir be pulled out it breaks near the lower end and the oval conidia and jointed threads of the parasite may be demonstrated by macerating this broken end. The disease is very contagious, chronic and resistant to treatment, but proceeds without inflammation or subjective sjTuptoms, the conspic- uous sign being loss of the hair. Cultures grow slowly and are snow white. Animal inoculation is rarely successful. Microsporon 'Pvcdai.—This mold is found in the superficial layer of the skin in pityriasis versicolor, as short thick hyphae 3 to 4m wide by 7 to 17,11 long, together with abuhdant doubly contoured single conidia. Pityriasis versicolor occurs most fre- quently on the skin of the chest and is one of the commonest affections of the skin. Tricophyton Actuninatum.—The niold invades the hair shaft and causes it to break off close to the surface of the skin. In such a hair long chains of oval cells of the parasite may be seen. The parasite also attacks the skin and produces ringworm. Several other species of tricophyton are distinguished. These parasites are concerned in the causation of barber's itch, eczema marginatum, tinea cruris, and other skin affections of this Pig. 102. — S porotrichum sohencki.
