. A text-book of bacteriology, including the etiology and prevention of infective diseases and a short account of yeasts, and moulds, haematazoa, and psorosperms. Bacteriology. DESCRIPTION OF SPECIES. 507 ^^^^ a shining white growth a,long the needle track which sends off long rounded processes. On agar, glycerine agar and blood serum they produce a luxuriant white shining growth. Broth becomes turbid with a whitish deposit and pellicle. On potato there is a thick moist brown growth. They are found in water. Bacillus cyaneo-fuscus (Beyerinck).âRods '2 to -6 ,/i in length, and half their length

On agar, glycerine agar and blood serum they produce a luxuriant white shining growth. Broth becomes turbid with a whitish deposit and pellicle. On potato there is a thick moist brown growth. They are found in water. Bacillus cyaneo-fuscus (Beyerinck).âRods '2 to -6 ,/i in length, and half their length in width. Motile. In the depth of gelatine they produce colonies in the track of the needle, -which later develop a black pigment. In broth with ^ per cent, of peptone they produce a blue colour, changing to brown and finally black. They were isolated from cheese, size and glue. Bacillus cyaneo-phospliores- ^lens (Katz).âRods 2-6 /i in length, 1 /i. in width, singly, in pairs, and filaments. Colonies circular and brownish or greyish-yellow. Jnoculated in the depth of gela- tine they form a grey-white fila- ment in the track of the needle and liquefaction follows at the upper part; later a skin forms on the sur- face and a yellow deposit occurs at the bottom of the liquefied jelly -which has a reddish-brown tinge. In broth a similar skin floats on the surface and the broth is turbid. On sterilised fish the growth is viscid and yell6w. Cultures are phosphorescent, especially in media containing excess of common salt. They were isolated from sea- water at Sydney, and are possibly identical with Bacillus phosphores- â cens of Fischer. Bacillus cyauogenus (Hueppe). âBacterium syncyanum.
