A novel biological rote of ?-L-fucose in mutans group streptococci

Abstract

This study includes (50) samples were collected from patients with dental diseases (30) swabs taken from dental carries and (20) swabs from periodontal cases, these patients were of both sexes, their ages ranged from 10-65 years. There results of bacterial culture were positive in (20) patients of mutans group streptococci. Versus (30) patients revealed other types of and negative cultures.it was found that (10) isolates (50%) were identified as St. mutans, where (8) isolates (40%) identified as St. salivaris, and (2) isolates (10%) identified as St. oralis. The inhibition effect of fucose in different concentration of bacterial growth were studied, the results showed that there is a great inhibition growth on all studied bacterial isolated form oral cavity (mutans group streptococci) and the best inhibition concentration of fucose on bacterial growth found to be (80mM).

Key words: Mutans group streptococci, Fucose
