Imferon agar: improved medium for isolation of pathogenic Neisseria

Abstract
Imferon, an Fe-dextran complex, enhances the growth of N. gonorrhoeae and N. meningitidis. The use of Imferon as a replacement for ferric nitrate, in a defined supplement for GC agar, significantly increased the average colony sizes of gonococci and meningococci. In comparison with Thayer-Martin medium, Imferon agar increased the speed and rate of isolation of gonococci from clinical specimens.
