Neisseria Chemically Defined Medium (NCDM) has been used routinely in our laboratory for a variety of purposes. The present report describes the development of NCDM agar, wherein the NCDM base is sterilized by filtration and defined supplements and agar are added. The medium is transparent and both meningococci and gonococci grow within 72 h. When grown on NCDM agar, Types 2 and 3 gonococcal colonies tend to revert to Type 1. The serological grouping of meningococci with specific antisera is not affected by growth on this medium.Parallel investigations on the growth of these species in liquid NCDM demonstrated that the yield of Neisseria gonorrhoeae is enhanced when the medium is sterilized by filtration.

When mature and immature uteri from ovariectomized mice were cultured in chemically defined media, blastocyst invasion occurred in the presence of progesterone but not in media containing only oestradiol. The invaded stromal tissue did not decidualize unless the uteri were taken from mice pretreated with progesterone and oestradiol. Fibrillar material was, however, concentrated in the stromal tissue adjacent to the invasive trophoblast. Neither progesterone nor oestradiol, had any ultrastructural effect on the endometrium of cultured uteri from ovariectomized mice, other than closure of uterine lumina in the presence of progesterone. Embryogenesis became abnormal, probably owing to the failure of formation of a suitable implantation chamber.
