Characterisation of Neisseria gonorrhoeae from women with simultaneous infections at two sites.

Infection with two strains of Neisseria gonorrhoeae was found in paired cultures from 8.7% (6/69) of women who had infections of the cervix, rectum, or urethra. Paired gonococcal cultures from each patient were characterised by auxotyping, susceptibility to four antibiotics, and acrylamide gel electrophoresis patterns of the gonococcal cell proteins.
