    septic intoxication. A peculiar disease, without abscess formation, occurred in some individuals, and was trans- missible with certainty to others by inoculation of a very small quantity of blood. Extremely small bacilli, chiefly in leucocytes, were shown to be the cause of the disease. One attack confers immunity. It is not inoculable upon field mice or rabbits. Malig-nant (Edema. — A spreading csdema ending fatally may be produced by inoculation of mice, guinea- pigs, or rabbits, with garden-mould. One form of fungus develops, and the cedema-fluid containing it is easily inoculable. There are two species of the genus vibrio—V. rugula and V. serpens; they occur in putrefying fluids, and are not pathogenic. The bacilli of Tubercle, Leprosy and Glanders have already been described. Order 4.—SPIROBACTERIA—These difler from Vibrio in making more screw-like and closer turns; river- water is their favourite habitat (Cohn). There are two Genera—Spirochceta, flexible with wide thread; Spirilhcm, stiff with narrow thread. Relapsing: Tever.—The Spirochceta Ohermeieri (Fig. 150, lo) often called spirillum, is found in the blood in this disease. It is 16-40 ^ long, and makes quick undulating movements. The organisms are generally said to appear m the blood soon after the commencement of an attack, and to disappear with remarkable speed after the crisis. Spitz, however, states* that by careful examination he found spirochgetse in the blood 2-4 hours before and after an attack. Nothing is seen of them till the relapse, whea they return. The disease has been inoculated from man on man, and from man on apes (Carter, Koch). Koch cultivated the Spirochseta Obermeieri; it grew into long threads.
