PATHOGENIC MOULDS AND YEASTS. 479 abscesses in various parts of the body, such as in the kings, spleen,kidney, and brain. In the lesions of the disease as well as in cultures, this fungus appearsboth as a yeast and a mycelium. It thus seems to stand between thetrue moulds and the yeasts.

Conidia; e. pus cells. (From Plautin KoUe and Wassermann.) The threads of the mycelium vary markedly in length and thickness,and show all intermediate forms between a typical and a budding-mycelium. Soor is not much influenced by acids or alkalies, growing well bothin acid and in alkaline media. On the other hand, it is very sus-ceptible to the common disinfectants, especially salicylic acid, cor-rosive sublimate, phenol, etc. This fact is made use of in localtreatment. BLASTOMYCETES (YEASTS). ihese microorganisms have been for manv centuries of the ta-eat-est importance in l^rewing and baking (p. 102). They are not uncom-monly present in the air and in cultures made from the throat. Cer-tain recent experiments have shown that some varieties when injectedare capable of producing tumor-like growths. Certain varieties arepathogenic for mice, and in recent years (since 1S94) there have beenreported a number of cases (twenty-three) of huniiin infection
