Mycoplasma arthritidis induces an acute to chronic arthritis in rodents. Arthritis induced in mice histologically resembles human rheumatoid arthritis and can be associated with lethal toxicity following systemic injection. The M. arthritidis mitogen (MAM) superantigen has long been implicated as having a role in pathogenesis, but its significance with(More)
The presence of capsular exopolysaccharide (EPS) in Mollicutes has been inferred from electron micrographs for over 50 years without conclusive data to support the production of complex carbohydrates by the organism. Mycoplasma pulmonis binds the lectin Griffonia simplicifolia I (GS-I), which is specific for terminal beta-linked galactose residues. Mutants(More)
The genome of Mycoplasma arthritidis strain 158 has modified cytosine residues at AGCT sequences that render the DNA resistant to digestion with the AluI restriction endonuclease. The DNA methyltransferase responsible for the base modification has previously been designated MarI. From the complete genome sequence of M. arthritidis, we identify Marth_orf138(More)
