At last you are unmasked you Azeff in skirts. False friend you would have killed us all Saratovsky, Kharkoff "Be still, little fool," exclaimed Nevsky contemptuously. "The spirilla fever has affected your brains. Bah! I will not stay with those who are so ready to suspect an old comrade on the mere word of a charlatan.
It is not too much to say that the demonstration by Koch of the "bacillus tuberculosis" is, in its far-reaching results, one of the most momentous discoveries ever made. Of almost equal value have been the researches upon the protozoan forms of animal life, as causes of disease. As early as 1873, spirilla were demonstrated in relapsing fever.
Some multiply by fission, others by sporulation. Some forms are motile, others are non-motile. Tuberculosis, tetanus, anthrax, and many other surgical diseases are due to different forms of bacilli. Spirilla are long, slender, thread-like cells, more or less spiral or wavy. Some move by a screw-like contraction of the protoplasm, some by flagellæ.
Now er Walter, look through the microscope under this powerful light and tell us what you see on the slide." I bent over. "In the darkened field I see a number of germs like dancing points of coloured light," I said. "They are wriggling about with a peculiar twisting motion." "Like a corkscrew," interrupted Kennedy, impatient to go on. "They are of the species known as Spirilla.
Thus we recognise those that are globular cocci; those that resemble a rod bacilli; the spiral or wavy forms spirilla.
Often these filaments are not straight, but spirally twisted, and are called "spirilla." Some of them are blood parasites, but the larger number attack the tissues, and others occur in the digestive canal.
On account of this developmental change, he doubted if the cholera organism should be ranked with bacilli; it is rather a transitional form between the bacillus and the spirillum. Possibly it is a true spirillum, portions of which appear in the comma shape, much as in other spirilla e. g., spirilla undula, which do not always form complete spirals, but consist only of more or less curved rods.
#The Virus of Syphilis.# The cause of syphilis, whether acquired or inherited, is the organism, described by Schaudinn and Hoffman, in 1905, under the name of spirochæta pallida or spironema pallidum. It is a delicate, thread-like spirilla, in length averaging from 8 to 10
"The spirilla, as scientists now know, belong to the same family as those which cause what we call, euphemistically, the 'black plague. It is the same species as that of the African sleeping sickness and the Philippine yaws. Last year a famous doctor whose photograph I see in the next room, Dr. Ehrlich of Frankfort, discovered a cure for all these diseases.
