A micro-organism is a parasite when it can live in animal tissues.
The micro-organism is found in the secretions from the mouth, throat, or nose, and in particles of detached membrane.
Altogether there are many obscure points about this micro-organism, which is apt to assume a puzzling variety of forms.
There are many kinds of fermentation, each with its own special form of minute plant life or micro-organism.
The micro-organism of small-pox and that of cancer (the existence of which is assumed) have not yet been isolated.
This he also proved to be caused by a minute form of life, and that fowl cholera is due to still another form of micro-organism.
The cause is a micro-organism identified by Koch in 1883 (see Parasitic Diseases).
It may produce chemical substances which act as poisons to the micro-organism, either paralysing it or actually killing it.
The discrepancy was probably due to an imperfect suspension of the micro-organism in the oil.
In that year Dr. Mueller took out a patent endeavoring to utilize the micro-organism in sewage for the purpose of purification.
