What shape are gram negative bacteria?
Gram negative bacteria is shaped like rods and stained a reddish pink color due to the gram staining process. Gram negative bacteria do not form spores.
Do bacteria reproduce through spores?
Endosposres are intracellular resting cells. With a few exceptions endospore formation is restricted to some large gram positive bacilli. Among cocci and spirila endospores are formed only in few species e.g. Sarcina lutea, S. ureae, Dusulfovibrio desulfuricans. Gramd negative do not form spores or endospores.

What is most common gram positive or gram negative bacteria?
