conclusions the results of our study, regarding the observed effects based on differences in concentrations, suggest that further and more comprehensive studies should be undertaken to determine the appropriate concentration for obtaining the effect of the extract of f. assa-foetida l. and q infectoria olivier on s. mutans and s. sanguis. results the aqueous and ethanolic extract of f. assa-foe...

background and objectives: streptococcus pneumoniae, a major human pathogen, is closely related to the commensal species s. mitis and s. oralis. s. pneumoniae surface proteins are implicated in virulence and host interaction of this species, but many of them have recently been detected in s. mitis b6 in silico. we tested for the presence of such genes usinga set of eight s. mitis and eleven s. ...

hyaluronidase has a panoramic use in biotechnology processes and therapy due to its therapeutic, pathophysiological, physiological and biological importance. since much of the preparations of hyaluronidases are from animal source (bovine and ovine testicular sources) with limited sources of microbial origin, that prompted the authors to screen and isolate a new promising bacterial strain with h...

background periodontitis is a major problem that affects a large number of patients in the society. various treatment alternatives have been proposed to control this pathologic condition. streptococcus sanguis is one of the countless pathogens involved in periodontitis. objectives the current study aimed to assess the efficacy of pineapple extract per se and in synergy with vancomycin on the gr...

abstract   background and aim: due to the increasing use of restorative materials, finding a  suitable material with low adhesion rate and colonization of pathogenic  streptococcus mutans has a significant importance. the purpose of this study was the  comparison of the adhesion rate of streptococcus mutans to “nano-hybrid composite” and “amalgam” at 1, 3, and 7 day  intervals. methods and mate...
