Bacteria [noun]

Bacteria, when present in great numbers, give a uniform cloud which cannot be removed by ordinary filtration.

It is to be remembered, however, that a few of these bacteria may reach the sputum from the upper air-passages.

Bacteria of various kinds, especially staphylococci, are usually numerous.

They are able to migrate readily from place to place and to ingest small bodies, as bacteria.

Undiluted normal blood can agglutinate most bacteria, but loses this power when diluted to any considerable degree.

They appear to be more or less specific, a separate opsonin being necessary for phagocytosis of each species of bacteria.

It has been shown that the quantity of opsonins in the blood can be greatly increased by inoculation with dead bacteria.

The microscope commonly shows sarcin, bacteria, and great numbers of yeast-cells.

This will show all bacteria except the tubercle bacillus, and often no other stain is necessary for their identification.

Gram's method (p. 40) is a very useful aid in distinguishing certain bacteria.
