Improved medium for the transportation of gonococcal specimens.

A modification of Stuart medium, denominated SIFF transport medium, was compared with Stuart (Ringertz's modification), Amies and SBL transport media for its ability to preserve viability of gonococci during transport. The SIFF medium was superior both when using laboratory strains of Neisseria gonorrhoeae and when using clinical specimens. The new transport medium distinguishes itself mainly by an increased osmotic pressure and by its starch content.
