Bacteria Taxonomy

Question 1 of 11

1

Describe Proteobacteria (generally)

Select one of the following:

  • Gram negative; outer membrane composed mainly of lipopolysaccharides; all oligotrophs

  • Gram negative; anaerobic, rod-shaped opportunistic; 2 main families

  • Gram negative; photosynthetic, thicker than normal peptidoglycan wall (10-700nm); single, multicellular, and colonial cells; pilli/fimbrae

  • Gram negative; double membrane with axial filaments in between for movement; facultative anaerobes

  • Gram positive; pathogens able to invade; split into high and low G+C content groups

Explanation

Question 7 of 11

1

What phylum is Borrelia burgdorferi from? What are the features of this species?

Select one of the following:

  • Spirochetes: it causes Lymes Disease, spiral in shape

  • Fusobacteria: It occurs in healthy younger populations causing peritansillar abscesses
