Mycoplasma arthritidis is a rat pathogen causing a severe polyarthritis.
The study of its pathogenic mechanisms has been hampered by the lack of
genetic systems for use with M. arthritidis. Described here are procedures
for genetic transformation of M. arthritidis and conjugal transfer of Tn916
from an enterococcal donor to M. arthritidis. The location of Tn916
insertion sites in the mycoplasmal chromosome was random, suggesting that
Tn916 may be useful as an insertional mutagen in this organism.
Additionally, a restriction and modification system was identified which
presented a strong barrier to gene transfer. For transformation, the
restriction system was circumvented by using DNA that was modified in vitro
with the appropriate site-specific methylase (AluI).
