Cockroaches and ants as carriers of the vibrios of Asiatic cholera.
The distribution and characteristics of vibrios isolated from certain non-human sources in Calcutta.
Pasteur announced more than six years ago the propagation of the vibrios of the silkworm disease called flacherie, both by fission and by spores.
Air, or rather the oxygen of the air, which is absolutely necessary to the support of the bacteria of putrefaction, is, according to Pasteur, absolutely deadly to the vibrios which provoke the butyric acid fermentation.
Precisely the reverse of all this occurs with the vibrios of butyric acid.
Compared with his atoms, the smallest vibrios and bacteria of the microscopic field are as behemoth and leviathan.
He claimed that while in puerperal processes vibrios are always present, in healthy women they never occur before the second, third, or fourth day, and not always even then.
They are frequently associated with sarcinæ, produced by fermentation in the contents of the stomach, and after standing for some time the liquid becomes crowded with vibrios (Lindsay).
These specially merit the name of vibrios of putrefaction, from the very putrid gases which result from their action upon nitrogenous and sulphurous substances.
The presence of septic vibrios in the blood of the inoculated rabbits escaped their notice.
In contact with air the cultivations of septic vibrios would prove sterile, because the vibrio is exclusively anaerobic and air kills it.
Moving vibrios make their appearance and multiply, the lactate of lime disappears, the fluidity returns to the mass, and the lactate finds itself replaced by butyrate of lime.
Are not vibrios which imperatively require for their nutrition and multiplication the presence of oxygen gas those which will never have the properties of ferments?
Of all the vibrios ready to pass from the intestinal canal into the network of mesenteric veins which surround the canal those which seem to take the foremost place are the septic vibrios.
The filaments of bacteria and the filaments of septic vibrios had perished under the influence of the compressed oxygen; but the spores were there, and the great pressure of oxygen gas had not affected them.
The vibrios live and multiply without the smallest supply of air or of free oxygen.
It will be found full of septic vibrios in process of generation by fission.
On making a direct microscopical examination we see that Koch’s vibrios become immovable, then break up into granulations and disappear in the liquid.
We then filled a similar flask, B, with the solution of lactate, which we boiled, not only to kill the germs of vibrios which the liquid might contain, but also to expel the air that it held in solution.
Hence we are forced to regard them as a distinct species; and so it is possible that there may likewise be aerobian and anaerobian vibrios without any transformation of the one into the other.
It would be easy enough to determine this point by growing the vibrios of such fermentation in media adapted to the production of the ordinary forms of vibrio; but this is an experiment which we have not ourselves tried.
The movements and fissiparous multiplication of the vibrios may thus be seen in all their beauty, and it is indeed a most interesting sight.
We may pause to consider an interesting question in reference to the two characters under which vibrios appear in butyric fermentations.
Must we, then, believe that such vibrios are absolutely different from those of butyric fermentations?
If a fluid containing septic vibrios be exposed to pure air, the vibrios should be killed and all virulence should disappear.
But how could we reconcile this, supposing it were proved to be the case, with the fact just insisted on as to the danger of bringing the butyric vibrios into contact with air?
Not one of these vibrios could be found throughout the mass of the liquid.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "vibrios" in a variety of sentences. We hope that you will now be able to make sentences using this word.
