Gaffky cultivated it from typhoid evacuations, from typhoid ulcers, from the mesenteric glands, and from the spleen. It is found in scattered colonies in the spleen, and is rarely if ever present in the blood. Bacillus of Typhoid Fever—Kods 1 to 3 /i in length, and -5 to '8 /x in breadth, and threads (Plate VIII., Fig. 2). Spore-formation has not been observed, but the protoplasm may be broken vip, producing appearances which may be mistaken for spores. They are actively motile, and provided some with a single and others with very numerous flagella, which are from three to five times as long as the bacilli. They stain well with aqueous solutions Fig. 131.—Typhoid Bacilli, X 950 (Baumgaeten)..
