Query: NC_011374:202936 Ureaplasma urealyticum serovar 10 str. ATCC 33699 chromosome,
Lineage: Ureaplasma urealyticum; Ureaplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: Causes a wide range of infections of the urogenital or respiratory tracts. Ureaplasma urealyticum is part of the normal flora of the human urogenital tract. This organism, however, can cause urethritis and has been associated with spontaneous abortion, premature birth, meningitis, and a severe respiratory disease of premature infants. U. urealyticum strains exhibit antigenic heterogeneity. Isolates obtained from human urogenital tract have been classified into 14 recognized serovars which show no serological cross-reactivity with ureaplasmas from other hosts and uniquely express human immuoglobulin A1 protease activity.
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.
