THE BACILLUS AN- THRACIS

(AF- TER DE BARY.) 237, 238.]—B. cavicida [Brieger], B. cavicidus. A rod-like oranism about twice as long as it is broad, obtained from human ‘æces. It forms on pela colonies in the form of Irregular concentric rings resembling the scales of a tortoise, and on potatoes dirty-yellowish colonies. It is very fatal to guinea-pigs, causiug death with marked signs of intestinal irritation. It is also said to decompose sugar into propionic acid. [B, 122, 238.)—B. choleræ usiaticæ. See SPIRILLUM choleræ asiatice.—B. cholers gall in arum. Fr., microbe (ou bacille) du choléra des poules. Ger., Syn.: Micro- B. der Hühnercholera (oder des Gefliigeltyphoids), found b; coccus choleræ gall in arum, B. of chicken-cholera, A Pasteur in the blood of hens affected with chicken-cholera. It forms very short, rod-like, non-motile cells from 1 to 1°2 u long and over 0°7 » thick. puey increase by division and often from median segmentation resemble diplococci, and present the same appearances as the latter when treated with coloring agents. In cultivations it forms whitish superficial colonies with uneven edges on gelatin and does not liquefy the latter. It is closely akin to the B. cuniculicidus, with which it very po ibly is identical. _ [B, 122, 209, 238.) See also B. of Wildseuche—BB. coprogenes fæœtid us [Schottelius]. A B. found in the intestine and neighboring organs of swine affected with hog-cholera. It forms non-motile rods about as large as those of B. subtil is, but somewhat shorter and with rounded ends, In the presence of air it forms spores arranged in rows, and the latter grow by lateral development. On cultivation it forms on Garner) colonies which are grayish superficially and yellowish in the deeper layers, do not liquefy the gelatin, and ‘are accompanied by an intense fæcal odor. potatoes it forms a light-gray coating. It has probably no connection with the disease of swine. [B, 28.|—B. coprogenes parvus [Bien stock]. A very smal] non-motile B, closely resembling the B. murisepticus, found in human feces and growing very slowly in agar-agar and gelatin. Injected into the blood of white mice and rabbits, it produces death with inflammation at the point of injection and intestinal symptoms. [B, 122, 238.]—B. era us [Van Tieghem]. A non-motile species remarkable for its thickne (4 4, and during the stage of sporification 6 «) and for the size of its globular spores (5 in diameter), one of which is found at each end of the B. [Van Tieghem, “Bull. de la soc. bot. de France,” 1879, p. 141; ** Bot. Jahresb.,”’ 1879, bis 598 (B).]—B. era us sputigenes [Kriebohm]. A short, thick B. with rounded ends. often a uming a sausage or spiral shape, found in the human sputum. These Bacilli increase by division, and ata temperature of 35° C. form spores. On cultivation they form on gelatin grayish colonies elevated above the surrounding surface, in needle-cultures nail-shaped colonies, and on potatoes a moist, grayish coating. Inoculated in mice, rabbits, and dogs, they cause death with symptoms of septicaemia and acute gastro-enteritis, [B, 238. —B, cuneatus. Syn.: Bacterium cuneatum [Rivolta]. A B. foun in putrefied blood, in the intestines of horses and dogs that have died from ‘* di olutive proce es,” and in cows affected with septic metritis. It occurs as elongated, wedge-shaped rods with rounded extremities and having a shining globule (erobenly) a spore) at the narrower end. [B, 30, 125) 8. cuniculicida [Koch], B. eunienlicidus. Fr., bactérie (ou bacille) de la septicémie des lapins, Ger., B. der Bree cleraepy Cnt The B. of the septicemia of rabbits; a species found in impure river-water and decayed me at brine, and closely resembling the B. choleræ gall in arum. It forms motionle rod-forms 1'4 w long and 0° to 0°7 y broad, which are frequently united in pairs or in figure-of-8 shapes. On gelatin it gives rise to nearly circular colonies with a dark pallowgt central zone and lighter colored periphery, Inoculated in rabbits, mice, and birds, it produces Ga and death, [B, 122, 238.] S . cyanogen us [Fuchs].
