A previously undescribed plasmid and African R plasmid in Neisseria gonorrhoeae isolated in Taiwan.

ABSTRACT

A new undescribed plasmid, 15.6-Mdal in size, was detected in Neisseria gonorrhoeae isolates in Taiwan. The plasmid was co-existent with 2.6-Mdal and 7.8-Mdal plasmids in three out of 190 clinical isolates. It appeared to be consisted of six copies of the 2.6-Mdal plasmids as evidenced by restriction endonuclease cleavage. In addition, African 3.2-Mdal R plasmids have also been detected in penicillinase-producing N. gonorrhoeae (PPNG) isolates in Taiwan. They accounted for 7% of PPNG.
