It is not necessary to isolate cases of erysipelas, provided the usual precautions against carrying infection from one patient to another are rigidly carried out. Diphtheria is an acute infective disease due to the action of a specific bacterium, the bacillus diphtheriæ or Klebs-Löffler bacillus.

You may be thankful you are one." "I am. It seems wonderfully grand and elegant for a person that is so humble as I am; but I am thankful, I am indeed, and will try to live up to it. It is hard to remember. Will you say it again, please, and say it slow?" "Plantigrade circumflex vertebrate bacterium that hasn't any wings and is uncertain."

Take, for example, the extensive array of widely different systems which have been invented during the last few years for the species of the genera bacterium and vibrio in the works of Cohn, H. Hoffmann, Hallier, and Billroth.

So I didn't say anything, and soon liked him very well indeed. Was it a compliment, do you think?" "Yes, that is what it was. They are very rare, the reptiles; very few left, now-a-days." "Is that so? What is a reptile?" "It is a plantigrade circumflex vertebrate bacterium that hasn't any wings and is uncertain." "Well, it it sounds fine, it surely does." "And it IS fine.

Yes! by a series of resolute efforts, in using a new battery of lenses the finest that at that time had ever been put into the hands of man I was enabled to show in succession that each motile form of Bacterium up to B. lineola accomplished its movements by fibers or flagella; and that in the act of self-division, constantly taking place, a new fiber was drawn out for each half before separation.

Others have regarded the whole bacterium as a nucleus without any protoplasm, while others, again, have concluded that the discerned internal structure is nothing except an appearance presented by the physical arrangement of the protoplasm. While we may believe that they have some internal structure, we must recognise that as yet microscopists have not been able to make it out.

"You see, that man came to my house to see me, and he is an Anarchist. No don't faint, or I cannot possibly tell you the rest. And I wanted to astonish him, not knowing he was an Anarchist, and took up a cultivation of that new species of Bacterium I was telling you of, that infest, and I think cause, the blue patches upon various monkeys; and like a fool, I said it was Asiatic cholera.

In the same way the term aseptic conveys the idea of freedom from all forms of bacteria, putrefactive or otherwise; and the term antiseptic is used to denote a power of counteracting bacteria and their products. #General Characters of Bacteria.# A bacterium consists of a finely granular mass of protoplasm, enclosed in a thin gelatinous envelope.
