Unformatted text preview: vegetative cells that move by gliding, leaving a slime trail. They feed on other bacteria. Large numbers aggregate (gather) and form a macroscopic fruiting body containing resting cells called myxospores. Later these myxospores germinate and form vegetative gliding cells. EPSILON-PROTEOBACTERIA ( ε -PROTEOBACTERIA) slender rods, helical to vibroid. Microaerophilic and motile by flagella. a) Campylobacter —vibroid with one polar flagellum 1) Campylobacter fetus —spontaneous abortions in domestic animals 2) Campylobacter jejuni —foodborne intestinal disease (diarrhea) b) Helicobacter— curved rods with multiple flagella. H. pylori is the cause of most peptic ulcers in humans and can even be involved in stomach cancer ....
