Resum
Strains of Neisseria sicca and N. mucosa, but not N. perflava, N. subflava, N. flava, or N. flavescens were found to grow on eosin methylene blue agar. The distribution of N. sicca on the tongue dorsum, the gingival crevice area, and the coronal surfaces of teeth of humans was determined using this medium. N. sicca averaged about 5% of the total cultivable organisms of the tongues of 14 subjects examined, but it was present in only trace quantities in dental plaque on the coronal surfaces of teeth or in the gingival crevice area.
