In 1879 a new stage of more precise knowledge of the venereal diseases began with Neisser's discovery of the gonococcus which is the specific cause of gonorrhoea. This was followed a few years later by the discovery by Ducrey and Unna of the bacillus of soft chancre, the least important of the venereal diseases because exclusively local in its effects.
Small doses of the organism have been injected into animals; then, when they have recovered, larger ones, and so on, after the manner of the bacillus of diphtheria, until a powerful antitoxin can be obtained from their blood, very minute quantities of which will promptly kill the bacilli in a test-tube.
Many germs can be grown artificially, some in the presence of air, others only when air is removed. The germ of syphilis belongs in the latter class. The germ that causes tuberculosis, a rod-like organism or bacillus, can stand drying without losing its power to produce the disease, and has a very appreciable ability to resist antiseptic agents.
The last and greatest achievement of medical science is not recorded in these pages. It is only recorded in ourselves. For that blue pigmentation in your eyes and fingers is due to the Sarakoff-Harden bacillus which closes once and for all the chapter of medicine." In a few hours the initial effects of stimulation had worn off.
You look as if they might be romantic, but I suppose you are really off on the quest of the blooming bacillus or the meandering microbe, or hanging over what is it you call your garden beds of disease a culture?" He looked up and patted her hand. "It is too bad not to be able to be a hero to one's own sister, but the truth is, I wasn't thinking at all, just wool-gathering.
Sarakoff emptied the remaining tubes calmly and then turned his footsteps in the direction of Rhayader. I waited a moment longer in the deep silence of that lonely spot; and then with a shiver followed my friend. The bacillus had been let loose on the world. We reached London next day in the afternoon.
A motile bacillus has been discovered which is supposed to cause the disease and there is evidence that this may be carried by a mosquito or fly, but until the discoveries of the doctors, sent out by the Liverpool School of Tropical Medicine, are published, it is premature to give an opinion. Up to the present many remedies have been prescribed without success.
They were loath to come; and, on being asked whether or not they wanted to go free if found clean of leprosy, one and all answered, "Back to Molokai." In the old days, before the discovery of the leprosy bacillus, a small number of men and women, suffering from various and wholly different diseases, were adjudged lepers and sent to Molokai.
You'll be sorry for the most beautiful woman in the The Bacillus of Beauty has had its victim. Why do I keep the wine-splashed, rose-breathing letter? Why read over and over the fragments of Helen's journal? Better remember my little school- mate as she was before the poison stung her.
It closely resembles the typhoid bacillus, but is distinguished from it by its behaviour in artificial culture media. [Illustration: FIG.
