Streptococcus mutans and Candida albicans are found together in the oral biofilms on dental surfaces, but little is known about the ecological interactions between these species. Here, we studied the effects of S. mutans UA159 on the growth and pathogencity of C. albicans. Initially, the effects of S. mutans on the biofilm formation and morphogenesis of C. albicans were tested in vitro. Next, w...

Streptococcus mutans, the predominant bacterial species associated with dental caries, can enter the bloodstream and cause infective endocarditis. The aim of this study was to investigate S. mutans biofilm formation and adherence to endothelial cells induced by human fibrinogen. The putative mechanism by which biofilm formation is induced as well as the impact of fibrinogen on S. mutans resista...

A laboratory experimental study conducted on antimicrobial effects of Coleus amboinicus, Lour folium Infusum towards Candida albicans and Streptococcus mutans (S. mutans). Effective concentration of Coleus amboinicus, Lour to decrease the quantities Candida albicans and S. mutans colonies is expected to be found out in this study. This study was using Coleus Amboinicus, Lour folium infusum with...

BACKGROUND AND AIM: Previous studies have shown that lactobacillus presented in food products affects oral ecology. In this study, we decided to show the effect of periodic use of Kidi Lact, a product containing probiotic bacteria which is recommended for improvement of gastrointestinal (GI) function in babies and children by physicians, on level of streptococcus mutans (S. mutans) in saliva am...

The gram-positive bacterium Streptococcus mutans is the primary causative agent in the formation of dental caries in humans. The ability of S. mutans to adapt and to thrive in the hostile environment of the oral cavity suggests that this cariogenic pathogen is capable of sensing and responding to different environmental stimuli. This prompted us to investigate the role of two-component signal t...

Streptococcus mutans (S. mutans), harboring biofilm formation, considered as a main aetiological factor of dental caries. Gtf genes play an important role in S. mutans biofilm formation. The purpose of this study was to investigate the effect of Lactobacillus acidophilus-derived biosurfactant on S. mutans biofilm formation and gtfB/C expression level (S. mutans standard strain ATCC35668 and iso...

background one of the most important factors in inducing the logarithmic growth of streptococcus mutans, is a diet containing fermentable carbohydrates such as sucrose. objectives: the aim of the current research was to compare the ability of ordinary and probiotic chocolate to induce or inhibit the growth of s. mutans. materials and methods lactobacillus rhamnosus, l. plantarum and l. acidophi...

BACKGROUND Mutans streptococci (Streptococcus mutans and S. sobrinus) are considered to be major etiologic agents of dental caries. Using a polymerase chain reaction method, we detected those bacteria from 145 outpatients (6-30 years old) with intellectual disabilities (ID) and their presence was compared with the incidence of dental caries. METHODS Plaque samples were collected from all erup...

Type II chromosomal toxin-antitoxin (TA) modules consist of a pair of genes that encode two components: a stable toxin and a labile antitoxin interfering with the lethal action of the toxin through protein complex formation. Bioinformatic analysis of Streptococcus mutans UA159 genome identified a pair of linked genes encoding a MazEF-like TA. Our results show that S. mutans mazEF genes form a b...
