Background and Objective: Since the preparation of antibacterial materials in dentistry is very noticeable, therefore, we tried to evaluate this effect on Streptococcus mutans by addition of silica nanoparticles to LCGI (light curing glass ionomer). Materials and Methods: In this in vitro study, we had five LCGI experimental groups that contained 0, 0.2, 0.5, 1, and 2% (w/w) of silica nanopa...
streptococcus iniae has emerged as an important fish pathogen over the last decade in farmed rainbow trout in iran. the main objective of this study was to evaluate the pathogenicity of s. iniae in poecilia reticulata . atotal of 60 apparently healthy p. reticulata were obtained from ornamental fish pet store and injected intraperitoneally with 1.5×10 6 cfu of bacteria. for 14 days after challe...
objective: punica granatum has been used for many years in folk medicine due to several purposes. the aim of the present study was to evaluate the effect of methanolic extract of punica granatum peel (mepgp) against streptococcus mutans, staphylococcus aureus, streptococcus salivarius, streptococcus sanguinis, staphylococcus epidermidis, actynomyces viscosus, lactobacillus acidophilus and candi...
Streptococcus agalactiae causes various severe infectious diseases such as sepsis, meningitis, and streptococcal toxic shock-like syndrome. Though Streptococcus agalactiae infection has been increasing recently, the comprehensive characteristic investigation of invasive Streptococcus agalactiae isolated in tertiary care hospitals has not been nearly performed in Japan. In this study, we investi...
abstract background: streptococcus mutans in the oral cavities sable to produce mutacin (bacteriocin-like substances) with antibiotic properties. the aim of this study was to investigate the frequency and expression of genes encoding mutacins typei, ii, iii and iv and also two of 8 genes in a cluster encoding the putative bacteriocins, the designated bsm 283, bsm 299, bsm 423, bsm 1889c, bsm 18...
Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout. A total of 520 samples were collected from the head kidney o...
