They measure to /t in length and to o.'7S n in breadth. Each is surrounded by a halo that varies in width from to m, which shows best in cultures grown on human blood-serum. The usual capsule stains fail to color this halo when the organisms are from artificial cultures, though they show it well when they are in pus. The organisms stain with ordinary dyes and by Gram's method. The cultures resemble those of Streptococcus pyogenes, but the organism ferriients inulin, which made Hiss think it related to the. ^ / .^' Fig. 107.—Streptococcus mucosus, from peritoneal exudate.

Streptococcus Erysipelatis (Fehleisen) The streptococcus of Rosenbach is generally thought to be iden- tical with a streptococcus described by Fehleisen f as Streptococcus erysipelatis. The streptococcus of erysipelas can be obtained in almost pure culture from the serum which oozes from a pxmcture made in the margin of an erysipelatous patch. They are small cocci, usually forming chains of from six to ten individuals, but sometimes reach- ing a hundred or more in number. Occasionally the chains occur in tangled masses. * "Miinch. med.
