In what manner does the tubercle-bacillus enter into the human organism?
But the tubercle-bacillus can also enter the body with the food, as stated before.
But it remained for Koch to bring light upon the conjectures of other scientists, and he established the fact, that the bacillus discovered by him was the real generator of pulmonary consumption.
Even in the year 1882 he has made known to the world the evil spirit in describing the tubercle-bacillus as the specific generator of tuberculosis.
Under what conditions is the tubercle-bacillus able to generate pulmonary consumption after it has entered the human organism?
All investigations, both of earlier and later date have established the fact that the tubercle-bacillus is inhaled with the air, and then it is mainly the foul air which is accused.
Even before the discovery of the tubercle-bacillus by Koch, different scientists had claimed that pulmonary consumption was caused by the immigration of bacteria into the lungs, and several of them had found bacteria of that kind.
Arriving at the army barracks near Havana the Commission first took up the study of Bacillus icteroides, the organism which Sanarelli, an Italian physician, had declared the causative agent in yellow fever.
It was clearly established that the claims of Sanarelli for Bacillus icteroides were without foundation.
Celli (1888) fed flies on pure cultures of Bacillus typhosus and declared that he was able to recover these organisms from the intestinal contents and excrement.
We shall next consider the role of the flea in the dissemination of the bubonic plague, an illustration complicated by the fact that the bacillus multiples within the insect and may be indirectly inoculated.
Typhoid fever is a specific disease caused byBacillus typhosus, and by it alone.
The sputum of tubercular patients is very attractive to flies, and various workers, notably Graham-Smith, have found that Musca domestica may distribute the bacillus for several days after feeding on infected material.
The basis was laid in 1894, when the plague bacillus was first discovered.
The causative organism is a bacillus and is not dependent upon any insect for the completion of its development.
Result: Carbolic acid showed a distinct germicidal action on typhoid bacillus in the proportions of 1 per cent.
Coli-Combined-Bacterin, said to contain killed Streptococcus viridans, Streptococcus hemolyticus and Bacillus coli.
Action of nitrogen gas on the growth of typhoid bacillus in bouillon and nutrient agar when chlorlyptus was added to this culture medium.
Colds characterized by catarrhal inflammation of the mucous membranes of the nose and throat are caused by various organisms, including a number of the commoner cocci and the bacillus of Pfeiffer.
Typhoid bacillus was destroyed in less than five minutes when exposed to the action of a 5 per cent.
March, 1906), who found commercial yeasts commonly contaminated with numerous bacteria, the most frequent being Bacillus coli-communis or one of its congeners.
Duplicate experiments were made with cultures of typhoid bacillus as above in bouillon and agar plates containing the same amount of chlorlyptus and incubated at 37 C.
The importance of thisbacillus is far beyond even its relation to necrotic stomatitis.
It is possible that many of these outbreaks have some relation to preceding cases of the above-mentioned diseases and the greater use in winter of the stalls and sheds, thus harboring the Bacillus necrophorus.
The bacillus of tuberculosis was discovered by Robert Koch in 1882.
It affects sucking calves chiefly, and is caused by the Bacillus necrophorus.
With pure cultures of this bacillus they were able to produce the disease artificially and to recover the same organism from the experimental cases.
As already explained, when the bacillus has become lodged in any organ or tissue it begins to multiply, and thereby causes an irritation in the tissue around it, which leads to the formation of the so-called tubercle.
In 1897 Bang, assisted by Stribolt, published their findings regarding infectious abortion of cattle, in which they incriminated Bang's bacillus of abortion as the causative agent.
As this bacillus vegetates and increases in numbers it excretes substances which act as irritants and poisons and which lead to the formation of a small nodule, called a tubercle, at the point of irritation.
Chronic bacterial dysentery is a chronic infectious disease of bovines caused by an acid-fast bacillus simulating the tubercle bacillus and characterized by marked diarrhea, anemia, and emaciation, terminating in death.
It would appear, therefore, that hereafter everyone must admit that it is impossible always to tell the source of a culture of the tubercle bacillus by its effect when it is inoculated upon cattle.
The experiments of Villemin were further productive in leading to the discovery by Koch of the bacillus tuberculosis.
This bacillus is not found in any other kind of sputum, is very abundant in pertussis, and increases in direct proportion to the severity of the disease.
The growth of the bacillus of malignant pustule takes place most vigorously at a temperature of 30.
Occasionally the bacillus is seen inside the mucous corpuscle in the sputum.
Bollinger has shown the presence of the bacillus in the stomach of such flies as fed on flesh and blood (horse-flies, bluebottles, etc.
Koch prefers a process of dry culture for the bacillus of tubercle.
The detection of the bacillus is not conclusive, as in tuberculosis and some forms of septicæmia there are similar organisms, agreeing with the microbe of glanders even in the matter of size.
The microbe of this malady, the Bacillus anthracis, occurs in the form of straight filaments with little movement or only with oscillation, and producing bright-shining spores.
The foulness of the mouth is supposed to be due to the colon bacillus and its allies, but those obtained from the mouth are innocuous.
The Bacillus typhosus discovered by Eberth is the causal agent of typhoid fever, and has its chief seat of activity in the small intestine, more especially in the lower half of the ileum.
But when it has no association with other trouble it is probably bacterial in origin, the Bacillus enteritidis spirogenes having been isolated in many cases.
True Asiatic cholera is due to the comma-bacillus or spirillum of cholera, which is found in the rice-water evacuations, in the contents of the intestine after death, and in the mucous membrane of the intestine just beneath the epithelium.
In a healthy new-born infant the mouth is free from micro-organisms, and very few are found in a breast-fed baby, but Bacillus lactis may be found where the child is bottle fed.
The bacillus has travelled forty-two miles towards Birmingham," he said, just as our train drew in to the London terminus.
And then a mood of unbelief would darken my mind and I would view the creation of the bacillus as an idle and vain dream, an illusion never to be realized.
Yes--the Bacillus Pyocyaneus," he said, with a faint mocking smile and a side glance at me.
A surge of power came over me as I thought of the bacillus which was so silently and steadily advancing on Birmingham.
The bacillus is not proof against death by violence," replied Sarakoff gravely.
The thought of the bacillus made the pages seem colourless; it dwarfed all meaning in the words.
The bacillus is in Birmingham by now," I said suddenly.
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.
Every man in this Hall who has the Sarakoff-Harden bacillus in his system is immortal.
I discovered the method whereby the bacillus became a possibility.
The bacillus is so small that one requires a powerful microscope to see him, and his blood may be infested with bacilli as small to him as he is to us.
Experiments were carried out, and it was assumed, not without good reason, that the bacillus was the primary cause of the malady, and it was accordingly labelled the typhoid bacillus.
I cut the following from a London morning paper: It was discovered some few years ago that a peculiar bacillus was present in all persons suffering from typhoid, and in all foods and drinks which spread the disease.
But the bacteriologists further discovered that the typhoid bacillus was present in water which was not infectious, and in persons who were not ill, or had never been ill, with typhoid.
Resemblances also exist between the endospores and the spore-formations in the Saccharomycetes, and if Bacillus inflatus, B.
A plate-culture of a bacillus which had been exposed for a period of four hours behind a zinc stencil-plate, in which the letters C and B were cut.

Sturgis, "A Soil Bacillusof the type of de Bary's B.
Furthermore, a bacillus may give rise to more than one toxic body, either as stages in one process of change or as distinct products.
In the last-mentioned disease even the local multiplication depends upon the presence of other bacteria, as the tetanus bacillus has practically no power of multiplying in the healthy tissues when introduced alone.
This is the case in the methods for staining the tubercle bacillus and also in Gram's method, the essential point in which latter is the treatment with a solution of iodine before decolorizing.
In the case of diphtheria Sidney Martin obtained toxic albumoses in the spleen, which he considered were due to the digestive action of an enzyme formed by the bacillus in the membrane and absorbed into the circulation.
Double staining is especially useful for spore-forming bacteria, so we may take some of the Hay Bacillus at sporing time.
The Hay Bacillus is one of the moving forms, each individual is furnished with a number of little whips whose lashings enable it to travel through the water.
The easiest subject with which to make a start is the Hay Bacillus, Bacillus Subtilis, not because it is the largest of the bacteria by any means, but because it is very easily obtained.
The germ which causes this fever has generally been supposed to be the bacillus of Eberth.
That a similar, though by no means so conspicuous, diminution of resistance to infection and intoxication by the bacillus coli communis also occurs in rabbits subjected to the same influences.
More recent bacteriological studies rather indicate that the bacillus coli may also cause the disease.
Bacillus botulinus produces a toxin that is extremely virulent.
In the stem of the glass I find the toxin of the Bacillus botulinus.
A badbacillus may be doing good work by holding down a worse one.
She could see, as he saw, the "beauty" of the long trains of research by which Sir Martin Crozier had tracked down the bacillus of amoebic dysentery and established the difference between typhoid and Malta fever.
This disease is caused by a bacillus that is often found in the soil, in manure, and in dust.
Good suggested "Bacillus abortivus equinus" as the name for the specific organism.
It is caused by the entrance into the animal's body of a bacterium, known as the Bacillus anthracis, or its spores.
Infection of an animal takes place through inoculation or contact of the bacillus or its spores with an abraded surface or mucous membrane, on a sound animal.
The causative organism is known as the Bacillus mallei.
Doubtless we may confidently expect his eventual suppression by a fresher and more ingenious disturber of the physiological peace, but the bacillus is now chief among ten thousand evils and it is futile to attempt to read him out of the party.
It follows that in order to deal intelligently with the criminal impulse in our afflicted fellow-citizens we must discover the bacillus of crime.
The bacillus is not to be denied; he has brought his blankets and is here to stay until evicted, and eviction can not be wrought by talking.
I have learned how to kill, or at least arrest, the bacillusof old age.
We grow old because every day we live beyond the age of thirty--the bacillus of old age is attacking us.
Suppose that in the colon is the tubercular ulcer, breeding the bacillus of consumption, and they are absorbed into the circulation.
In most of the avocations of life the shoulders are drawn forward, thus cramping the lungs, and weakening them, then the consumption bacillus finds lodgment.
Is a very contagious eruptive fever, caused by a bacillus and fever, with aching of the limbs, in from nine to twelve germ peculiar to the disease.
The cause is believed to be infection by the bacillus leprae, a specific microbe discovered by Armauer Hansen in 1871.
Diagnosis is established by the presence of the bacillus leprae in the nodules or bullae, and by the signs of nerve degeneration exhibited in the anaesthetic patches of skin and the thickened nerve trunks.
Thus it was absolutely proved, though the bacillus itself had not been found, that yellow fever is carried by mosquitoes, and is not carried by ordinary contagion.
Bacillus icteroides (Sanarelli) stands in no causative relation to yellow fever, but, when present, should be considered as a secondary invader in this disease.
Sternberg himself, had become convinced by comparing many cases of yellow fever that there was some intermediate host for the bacillus that caused the disease.
Finlay's experiments by the method of difference had failed, however, indisputably to establish the cause, since he did not see that it was necessary to allow the bacillus at least twelve days for incubation in the body of the mosquito.
The least trace of Gomenol prevents the growth in vitro of the streptococcus, the tuberculous bacillus and the gonococcus.
Surely this is so, they say, for is not typhoid fever due to the bacillus typhosus and pneumonia to the pneumococcus?
The tubercular bacillus is a scavenger and therefore does not thrive in healthy bodies.
These ferments have as their basis the lactic acid bacteria, and if the manufacturers wish to call their germs by other names, such as Bacillus Bulgaricus, no harm is done.
The tubercular bacillus is never able to gain a foothold in healthy lungs, but after degeneration of lung-tissue has taken place the lungs furnish a splendid home for this bacillus.
Metchnikoff thought this was a unique opportunity to learn whether there were any carriers of the plague bacillus among those many natives coming from all parts of the steppes.
At that time, the best-known microbe was the bacillus of anthrax.
Thus, by cultivating the lactic bacillus in the presence of those microbes which produce poisons belonging to the aromatic group, the decrease in quantity and even the disappearance of phenol and indol is observed.
One of the micro-organisms experimented with was a bacillus known at that time as the rinderpest bacillus, capable of producing disease in animals when inoculated into them and existing both in the spore and bacillar form.
On the other hand, similar experiments in which the typhoid bacillus was used resulted in the latter not only enduring a freezing of four days' duration, but emerging triumphant after it had been carried on for more than 103 days!
The anthrax bacillus cannot produce the hardy spore form within the bodies of animals, but it does outside.
Belli, of the University of Padua, in the experiments which he made with the fowl-cholera bacillus and the anthrax bacillus in the presence of very low temperatures.
But, although the typhoid bacillus appears to submit and meekly succumb to this plan of campaign, yet the conclusion must not be rashly drawn that all descriptions of bacteria will be equally feeble and helpless in these circumstances.
It is highly satisfactory to find that the character of this mouse-bacillus has stood the test of time, for after a period of more than ten years most encouraging reports concerning its efficiency still continue to be received.
Doctors Percy Frankland and Templeman have shown that the spore form of the anthrax bacillus is able to successfully challenge all such attempts upon its vitality.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "bacillus" in a variety of sentences. We hope that you will now be able to make sentences using this word.
