Singularly enough, the bacterium termo and the bacterium commune--to which the fetidity of matters undergoing putrefaction is due--are in themselves harmless.
Bacterium termo is regarded by leading authorities as the special ferment or causative agent of putrefaction[26] (Billroth, Cohn).
Vegetable parasites, like the bacterium and aspergillus, have also been included in the list, although the disturbances resulting from their presence are less due to mechanical obstruction than to colonization and growth.
The bacterium termo, which causes putrefaction, is not in itself, as we have already mentioned, a source of danger.
Some recent authors included bacterium and bacillus under one genus, bacillus; against which simplification there seems to be no valid objection.
On the other hand, he did assign this relation to a species of bacterium found in the walls of the intestine, and which he compared to the bacilli of glanders.
I have little doubt that the Bacterium coli, which lives in water, was very abundant in both of them.

The finished bacterium perishes at a temperature far below that of boiling water, and it is fair to assume that the nearer the germ is to its final sensitive condition the more readily will it succumb to heat.
In Pasteur's researches the Bacteriumremained a Bacterium, the Vibrio a Vibrio, the Penicillium a Penicillium, and the Torula a Torula.
We have seen that bacteria differ greatly in appearance from the elongated dot of the bacterium proper, to the elongated rod or cylinder of the bacillus, and the long spirals of spiro-bacteria.
In the study of the relation of a given bacterium to a certain disease, it becomes necessary to attend carefully to three different operations: First, the organism supposed to cause the disease must be found and isolated.

On the stage of the instrument, the Bacterium with its flagellum in distinct focus is placed.
Haying ascertained this, I determined to discover the ratio of thickness between the body of the Bacterium and its flagellum--that is to say, to discover how many of the flagella laid side by side would make up the width of the body.
In fact the pioneer is this--the ubiquitousBacterium termo.
Some of the specific organisms in this class are Bacillus subtilis, Bacterium prodigiosus and Bacterium liquefaciens.
Some of the groups are: Bacterium lactis acidi, B.
For this purpose the initial souring for most types of cheeses is produced by some variety of the species originally described by Esten[23] and commonly referred to as Bacterium lactis-acidi, but variously named as B.
It has been shown thatBacterium lactis acidi is able to form acid in the absence of the living cell.
This group takes its name from a typical species, Bacterium coli communis, which is a normal inhabitant of the intestines of man and animals, and from Bacterium coli aerogenes, which is similar in many respects to B.
This group contains different kinds of organisms which may be subdivided into small groups as follows: (a) Bacterium lactis-acidi group.
The development of Bacterium lactis acidi is followed by the growth of another group of acid-forming bacteria, the Bacillus Bulgaricus group.
The total acidity produced by these forms is less than that by the Bacterium lactis-acidi group.
The infectious agent is a bacterium first described by the Danish investigators, Bang and Stribolt.
Atkinson is pretty certain that he has isolated a very motile bacterium in the snow.
Sometimes also the virulence of a bacterium for a particular kind of animal becomes lessened on passing it through the body of one of another species.
It should be mentioned that different genera require different races of the bacterium for the production of nodules.
They were first described by Dr George Thin, who gave them the name of Bacterium decalvens.
The simplest case is that in which only one variety of bacterium is present, and a "pure culture" may then be obtained at once.
Egg-shaped mass of zoogloea of Beggiatoa roseo-persicina (Bacterium rubescens of Lankester); the gelatinous swollen walls of the large crowded cocci are fused into a common gelatinous envelope.
The result of the entrance of a virulent bacterium into the tissues of an animal is not a disease with hard and fast characters, but varies greatly with circumstances.

But this has not been proved, and hitherto no enzyme has been separated from a pathogenic bacterium capable of forming, by digestive or other action, the toxic bodies from proteids outside the body.
With regard to the subject of infection the chief factor is susceptibility; with regard to the bacteriumvirulence is all-important.
These oxidations are brought about by the vital activity of several bacteria, of which four--Bacterium aceti, B.
By this is meant the aggregation into clumps of the bacteria uniformly distributed in an indifferent fluid; if the bacterium is motile its movement is arrested during the process.

The remarkable class of the flagellata, which includes ciliated unicellulars of both groups, contains several forms which are only distinguished from the typical bacterium by the possession of a nucleus.
This quiescent form is assumed by the bacterium if its supply of food is exhausted; if fresh food is added, the multiplication by cleavage begins again.
Each bacterium is an independent cell and although the cells in some species remain attached to one another, giving rise to characteristic groupings, they are mostly detached and free individuals.
Accepting the general rule that simplicity of structure indicates priority, what then was the food supply of the primordial bacterium before the advent of higher plants to supply requisite organic matter?
Mueller, who finds that this bacteriumcan similarly acquire and maintain the power to ferment other sugars.
All these forms represent the different transformations of Bacterium termo, or the microbe of putrefaction.
One of the most common microbes in nature is the bacterium of putrefaction, found everywhere in decaying organic matter.
The first had been inoculated with the infectious blood of the dead woman, the second with the bacterium of splenic fever blood from Chartres, the third with the blood of a cow which had died of splenic fever in the Jura.
The blood arrived at the laboratory, and some days after Pasteur wrote to the doctor, 'Your leptothrix is nothing else than the bacterium of splenic fever.
When, for example, the bacterium of splenic fever is sown in the liquid, it assumes in a few hours a surprising development.
Chamberland, has given that proof, as he did in the case of the bacterium of splenic fever, by resorting to the method of successive cultivations in an artificial medium.
This form of suppuration is due to a particular form of bacterium called the pus-causing "chain coccus.
If the surroundings are too hot, too cold, or too dry, or if they are not supplied with a proper quantity and quality of food, the bacterium becomes inactive until the surrounding circumstances change; or it may die absolutely.
Then this particular form will no longer thrive; but some other form of bacterium may find in it the properties required for functional activity, and may grow vigorously.
Each kind of bacterium requires its own special environment to permit it to grow and flourish.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "bacterium" in a variety of sentences. We hope that you will now be able to make sentences using this word.
