| Abstract: | In present study, methanol extracts of the
Chlorophycean group of seaweeds have been tested for their antibacterial
activity against oral bacteria causing dental caries. Different concentrations
of the extracts of the four species of seaweeds- Chaetomorpha antennina, Cladophora fascicularis, Spongomorpha indica and
Ulva fasciata collected from sea
coast of Visakhapatnam have been tested for their antibacterial activity
against three oral pathogenic bacteria, Actinomyces
viscosus (MTCC 7345), Streptococcus
mitis (MTCC 2696), and Streptococcus
mutans (MTCC 1943). The antibacterial sensitivity was studied by Agar disc
diffusion method. Of these, U. fasciata
has shown greater inhibition on all the three oral bacteria than C. antennina, C. fascicularis and S. indica. C. fascicularis has inhibited S.
mitis and A. viscosus whereas C. antennina and S. indica inhibited only A. viscosus.
The present findings reveal that these seaweeds
have the potential antibacterial substances which can be used against oral
pathogens as food additives, mouthwashes, chewing gums for preventing and treating dental caries. |
