Rhodococcus equi
Classification

Genus Species
Rhodococcus; Rhodococcus equi
Description and Significance
Rhodococcus equi, originally discovered in horses by Magnusson, is a pathogen that is known to be able to affect animals and humans [4]. R. equi is a gram-positive coccobacillus that has the ability of producing a red pigment. It is a non-motile bacteria from the phylum Actinobacteria that is also aerobic and non-sporulating [1].
Structure, Metabolism, and Life Cycle
Interesting features of its structure; how it gains energy (how it replicates, if virus); what important molecules it produces (if any), does it have an interesting life cycle?
Ecology and Pathogenesis
Natural habitat (soil, water, commensal of humans or animals?)
If relevant, how does this organism cause disease? Human, animal, or plant hosts? Important virulence factors, as well as patient symptoms.
