THE BACILLUS CYANOGEN US

[B, 246.] lait bleu. Ger... Pilz (oder B.) der blauen Milch. Syn.: Bacterium syncyanum [Schrôter] (seu cyanogenum [Fuchs]), Vibrio cyanogen us [Fuchs] (seu syncyanus [Ehrenberg]). A B. producing in milk a grayish color which in the presence of free acids becomes a bright blue. This diseased condition of milk, which is inoculable, is due to the conversion of the casein into a blue coloring matter. The B. forms motile rods from 1 to 4 w long and 03 to 05 u thick with somewhat rounded extremities, and increases by division and by the formation of terminal spores, the latter giving to the B. a clubbed shape. On gelatin plates the Bacilli form granular whitish colonies, in needie-cultivations nail-like colonies with the evolution of the characteristic pigment, and on potatoes yellowish colonies with pigment-formation; in serum they Eee Without the development of pigment. It does not liquefy gelatin. {B, 122, 237, 238.]—B. den it rif i cans. Syn.: Bactcrium denitrificuns [Gayon and Dupetit]. A name given to two varieties of B. ‘obtained from sewage, differing somewhat in the rate of their development and in their ph; iological action, but alike in morphological characters. They are actively motile, from 2 to 4 x long and 04 to 0° x broad, and multiply at first by fi ion, afterward by endogenous spore-formation, from one to three spores being formed in each B. They convert nitrates into nitrogen and nitrous oxide; and in the presence of organic matters carbon dioxide is also formed from the combination of the oxygen of the nitrates with the carbon of the organic substances.

A B. found in diphtheritic membranes and those of laryngeal croup, forming straight or slightly bent non-motile rods as long as the B. tuberculosis and about twice as thick and often bent or swollen at one or both ends. These terminal swollen portions are more highly refractive than the remaining portions of the rods and are believed by some to show evidences of spore-formation, though this is doubtful. These Bacilli readily undergo _retrogre ive changes and present various involution forms. Introduced into the substance of the mucous membranes of birds and rabbits, these Bacilli produce diphtheritic symptoms and the formation of a false membrane.

A B. found in the epidemic diphtheria of doves, forming slender rods over 1°5 lon: and 0°3 to 0‘4 w thick. They form whitish colonies on gelatin, whic! they do not liquefy. Inoculated upon doves, they produce the origi- | nal disease. [B, 209, 237, 238.]— B. diphtheriæ vitulor: {Liffier]. Fr., bacille de la diphthérie des veaux.

A B. producing a peculiar fermentation of bread by which the latter becomes gummy and uneatable and develops aPeculmr odor like that of a mixture of oil of turpentine and oil of peppermint. It forms long filaments composed of long rod-like forms which break up into short rod-like forms and cocci and also form ellipsoidal spores. [B, 237.]—B. epsilon von Mil- .). See Epsilon B.—B. erythrosporus fEldam, Cohn]. A B. found in meat-infusions, drinking-water, and liquids containing decomposing albuminous matter. It forms slender motile rods with blunt, rounded ends, often connected -into short filaments. They develop in their interior a row of from 2 to 8 oval spores of a dirty-red color. On gelatin plates they form whitish colonies with a greenish-yellow zone surrounding an opaque, brownish centre, from which subsequently radial wavy lines develop, the whole colony then a uming a fluorescent green hue. Needle-cultivations are green by transmitted light, yellow by reflected light, and potato- Cultivations are at first red, afterward brown. [B, 237, 238.]—B. ex pnenmo-enter i tide suis [E. Klein].

Ger., Glycerinäthylbacillus, A B. found by Fitz in hay-infusions and having the property of inducing a fermentation in glycerin by which the latter is converted into ethyl alcohol. It forms short rods, long rods, and filaments of a breadth of 1 y and a length of 12uto many». It develops spores like the B. subtil is, and on gelatin forms brownish-yellow colonies with dark, nearly opaque centre. According to Fitz, it is the true B. subtil is of Cohn, According to Buchner, it is identical with the B. subtil is and Pasteur’s vibrion butyrique.” [B. 237, 238; “ Bot.
