Background & Objectives: Dental caries is the most important disease caused by some bacteria specially Streptococcus Mutans from Viridans family. The aim of this study is to evaluate the inhibitory effect of Chlorella vulgaris extract on growth, proliferation, and biofilm formation of Streptococcus mutans. Materials & Methods: Microalgae Chlorella vulgaris was extracted via maceration using ch...
Growth inhibition of Aspergillus fumigatus,Aspergillus flavus and Fusarum solani exposed to the essential oils including Thyme, Agastache and Satureja were studied. Disc Diffusion Method was used to evaluate the fungal growth inhibitory effects of the essential oils. Minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of the oils were determined and compared with ...
growth inhibition of aspergillus fumigatus,aspergillus flavus and fusarum solani exposed to the essential oils including thyme, agastache and satureja were studied. disc diffusion method was used to evaluate the fungal growth inhibitory effects of the essential oils. minimal inhibitory concentration (mic) and minimal fungicidal concentration (mfc) of the oils were determined and compared with e...
Background & Aims: Oral infections and dental caries are still considered as serious public health problems especially in developing countries. It is reported that Glycyrrhiza glabra (G.glabra) extract contains phytomedicine with antibacterial and antifungal properties capable of suppressing oral pathogens associated with plaque forming, caries or fungal diseases. The aim of this study was the ...
In this study, we report the green synthesis of silver nanoparticles (AgNPs) from extracts of native fruits from Amazonia, Brazil. AgNPs were characterized by UV/Vis and medium infrared (MIR) spectroscopy. Their antimicrobial activities were evaluated against the growth of bacteria and leavers, as well as the evaluation of minimum inhibitory concentration (MIC) and minimum bactericidal c...
Penicillin-resistant and penicillin-tolerant mutants have been isolated from group A streptococci mutagenized by ethyl methane sulfonate. The resistant mutants had an elevated minimal growth inhibitory concentration for benzylpenicillin (minimal inhibitory concentration, 0.2 microgram/ml, as compared with the minimal inhibitory concentration of 0.006 microgram/ml in the penicillin-susceptible p...
conclusions the kin gingival chlorhexidine mouthwash has a greater effect than behsa and boht mouthwashes on oral microorganisms and is recommended to be used for plaque chemical inhibition. results the mics for kin gingival, behsa and boht mouthwashes were 0.14, 0.48 and 1000 micrograms/ml using the tube method for s. mutans, respectively. the mbcs for the mentioned mouthwashes were 0.23, 1.9 ...
Twenty-two susceptible strains of Haemophilus influenzae were examined for mutation to rifampin resistance (minimal inhibitory concentration, greater than or equal to 10 micrograms/ml). All strains had detectable apparent mutation frequencies with a median minimal inhibitory concentration 2,000-fold greater than that of their wild-type parents. Of the type b strain mutants, 80% (8 of 10) expres...
