HZMATOCOCCUS BOVIS (Babes). 
Obtained by Babes (1889) from the blood and various organs of cattle 
which had died of an epidemic malady (in Roumania) characterized by haemv- 
globinuria. The cocci are found in the blood in great numbers, for the most 
part enclosed in the red corpuscles. 
Morphology.—Biscuit-shaped cocci united in pairs; sometimes oblong in 
form, isolated or united in groups; the free cocci are surrounded by a pale- 
yellowish, shining aureole of 0.5 to 1 w in diameter. 
Stains best with Léffler’s solution of methylene blue; does not stain by 
Gram’s method. 
Biological Characters.—An aérobic and facultative anaérobic, non- 
liquefying micrococcus. Grows very slowly at the room temperature—not 
below 20° C. In the incubating oven grows in the usual culture media. In 
gelatin stab cultures a scanty development of small, white colonies occurs 
along the line of puncture. Upon the surface of agar small, transparent 
drops are developed along the impfstrich. Upon potato, at 37° C.. a thin, 
broad, yellowish, shining layer is developed in the course of a few days— 
scarcely visible. Upon blood serum small, moist, transparent colonies are 
developed. 
Pathogenesis —Pathogenic for rabbits and rats, which die in from six to 
ten days after inoculation with a pure culture; the spleen is found to be en- 
larged, the lungs hypereemic, and a bloody serum is found in the cavity of 
the abdomen; the cocci are present in the blood in considerable numbers, 
but are rarely seen in the red corpuscles. Inoculations in oxen, horses, 
goats, sheep, guinea-pigs, and birds were without effect. 
STREPTOCOCCUS PERNICIOSUS PSITTACORUM. 
Micrococcus of gray pirrot disease. Eberth and Wolff have described 
an infectious disease of gray parrots, which is said to be extremely fatal 
among the imported birds. The disease is characterized by the formation of 
nodules upon the surface and in the interior of various organs, and especially 
in the liver. Micrococci of medium size are found in these nodules and in 
blood from the heart; these are sometimes in chains. Microscopic examina- 
tion of stained sections shows that these cocci are directly related to the tis- 
sue necrosis which characterizes the disease. But the micrococcus has not 
been cultivated and its biological characters are undetermined. 
STREPTOCOCCUS AGALACTIAZ CONTAGIOS AL. 
Obtained by Adametz (1894) from the milk of cows suffering from mas- 
titis (Gelben Galt). According to Adametz all of the streptococci which 
have been described by different investigators (Kitt, Nocard and Mollereau, 
Guillebeau, and others) are probably varieties of a single species. 
Morphology.—Spherical cocci in short chains—1 » in diameter. 
Biological Characters.—An aérobic and facultative anaérobic, non- 
liquefying streptococcus. : ; ; 
pon gelatin plates forms flat, transparent, white or bluish-white, 
slimy colonies, having a slight pearly lustre and an irregular outline. In 
nutrient gelatin containing five per cent of milk sugar the colonies, at the 
end of eight.days, have a diameter of 0.85 to 1 millimetre; they are milk- 
white and of a semi-fluid, slimy, consistence. 
Upon agar plates the deep colonies are punctiform and white in color— 
under a low power they are seen to have an irregular dentate contour and a 
brownish color; the superficial colonies gradually assume the appearance 
of transparent, flat drops having a diameter of 0.5 to 0.7 millimetre. In 
sterilized milk fermentation occurs, at 37° C., in from twenty to twenty-four
