Query: NC_014109:393500 Candidatus Riesia pediculicola USDA chromosome, complete genome
Lineage: Riesia pediculicola; Riesia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Riesia pediculicola is a bacterial symbiont of the human body louse Pediculus humanus. This organism is associated with the stomach disc in the louse and is essential for the survival and growth of the host.
Subject: NC_014014:359217 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.
