Spiroplasma

AntWiki: The Ants --- Online

From [Wikipedia]: A genus of Mollicutes, a group of small bacteria without cell walls. Spiroplasma shares the simple metabolism, parasitic lifestyle, fried-egg colony morphology and small genome of other Mollicutes, but has a distinctive helical morphology, unlike Mycoplasma. It has a spiral shape and moves in a corkscrew motion. Most spiroplasmas are found either in the gut or haemolymph of insects, or in the phloem of plants
