The term arthrospores has been given to them to indicate that they are formed as joints or segments, and this term may be a convenient one to retain although the bodies in question are not true spores.
These so-called arthrospores have never been observed to "germinate," nor is their resistance very marked, as they fail to initiate new cultures, after having been exposed to a temperature of 80° C. for ten minutes.
-- Certain species of bacteria do not produce spores as just described, but may give rise to bodies that are sometimes called arthrospores.
Formerly two kinds of spores were described, _arthrospores_ and _endospores_.
A chain of _cocci_ of _Leuconostoc mesenterioides_, with two "resting spores," _i. e._ arthrospores.
Systems have also been brought forward based on the formation of arthrospores and endospores, but as explained above this is eminently unsatisfactory, as arthrospores are not true spores and both kinds of reproductive bodies are found in one and the same form.
