Untitled edit
I'm questioning my last edit. They had written that diplococcus typically occurs as two pairs of joined cells, which I assumed was meant to be just two joined cells, but I have no evidence other than my gut instinct and the context I've always heard diplococcus used in my bio textbook. There's also the statement of diplococcus typically describing a bacterium consisting of two cells; what else could it be? I'm just a sophomore in college, so my knowledge pertaining to biology isn't disarming, but I don't see where else the term could be used. That statement leaves me wanting more. First thought of protists, but then realized the "coccus" part. There's also the fact that bacteria exist in 1+ cell forms (with diplococcus describing the 2-cell structure), and I don't understand the utilization of "typically". If it's only there to cover ignorant use of the word, it's unnecessary and confusing. I hope someone can shed some light with explanation/sources, and that I didn't waste 10 minutes :) Chemjunkie (talk) 00:52, 19 November 2011 (UTC)

Are Diplococci really always Gram-negative? edit
Perhaps it's just a bit of bad wording in the article, but the way the following sentences are written…
- “Examples are Moraxella catarrhalis, Neisseria gonorrhoeae and Neisseria meningitidis. Of these, all are Gram-negative.”
… seems to imply that all Diplococci are Gram-negative. Or perhaps it just means that the three examples that were explicitly cited are Gram-negative, but not necessarily that all Diplocicci are.
The reason I ask is that I came to this article just after having taken the picture below, showing some bacteria of the Diplococcus form, but which are clearly Gram-positive (stained purple). Also appearing in this image are some Streptobacillus which are Gram-negative (stained pink).
The two numbered ticks marks (5 and 6) are eleven microns apart. The unnumbered ticks are 1.1 microns apart.
