Query: NC_018664:1 Clostridium acidurici 9a chromosome, complete genome
Lineage: Gottschalkia acidurici; Gottschalkia; ; Clostridiales; Firmicutes; Bacteria
General Information: Clostridium acidiurici is an obligate anaerobic Gram-positive bacterium that is motile and spore-forming. It can be isolated from almost every soil but can also be found in the intestinal tract of birds. It is able to use purines like uric acid as sole carbon, nitrogen and energy source to build ammonia, carbon dioxide and acetic acid. Unlike most other Clostridia it is a specialist and not able to grow on sugars or different other substrates than purines.
Subject: NC_014014:153837 Mycoplasma crocodyli MP145 chromosome, complete genome
Lineage: Mycoplasma crocodyli; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: Mycoplasma crocodyli was isolated from the joint of a crocodile with exudative polyarthritis. The siblingspecies of M. crocodyli, Mycoplasma alligatoris causes acute lethalprimary infection of susceptible hosts, notably American alligators.This pathogen is studied to understand the mechanisms and evolutionaryorigins of that virulence. A genome survey indicated that M. alligatorisuses sialidase (Nanl) and hyaluronidase (NagH) to generate fuel forglycolysis from host cell glycans. M. crocodyli, which does not causedisease in American alligators, possesses NagH but not Nanl, so damageto the host's extracellular matrix alone cannot explain the particularvirulence of M. alligatoris.
