Relationship between plasmid content and auxotype in Neisseria gonorrhoeae isolates.

RESUMO
One hundred and forty strains of Neisseria gonorrhoeae, representing 12 different auxotype groups, were examined for differences in plasmid content. Most auxotype groups harbored a phenotypically cryptic 2,6-megadalton plasmid; a few groups also carried a 24.5-megadalton plasmid which has been previously characterized as a transfer plasmid. However, isolates of the proline-, citrulline-, and uracil-requiring (PCU-) auxotype were consistently free of plasmids. The correlation between auxotype and plasmid content is especially significant since, in Canada, PCU- isolates have the second highest prevalence of all auxotypes.
