[Comparative studies of the oral flora in patients with cancer and precancerous lesions  of the mouth mucosa].
Bacteriological smears were taken from various regions of the oral cavities of a total of 100 subjects (patients with carcinoma, non-specific ulcer or leucoplakia, and patients without pathological oral findings). The preparations were stained by the Gram procedure and differentiated according to germ count, morphology and ability to combine with dyes. Gram positive cocci prevailed in all groups. The total germ counts were greater in patients with carcinoma than in those with nonspecific ulcer and in normal subjects.
