Résumé
The dorsal surface of three-day postnatal mouse tongue was examined by field emission scanning electron microscope and revealed that the fungiform papillae are round in shape and filiform papillae present small projection in development. The surface of interface of epithelium-connective tissue showed small projections of papilla corresponding to the filiform and fungiform papillae. The surfaces of epithelial cell membranes present numerous microplicae with adhesion of streptococcus. These bacteria are attached on the cell membrane in organized rows of rat random, demonstrating their three-dimensional FESEM images. At high magnification, on ther surface of each bacteria may be noted small particles.
