five strains of mouth normal microflora containing staphylococcus epidermidis, streptococcus mutant, lactobacillus acidophilus, actinomyces viscosos and candida albicans, were isolated and identified then cultured and purified on different media by using routine methods in microbiology. extract of 3 garlic samples south (khuzestan), north (mazanderan) and hamedan garlics, were affected on these...

OBJECTIVE Acetaldehyde is the first metabolite of ethanol and is produced in the epithelium by mucosal ALDH, while higher levels are derived from microbial oxidation of ethanol by oral microflora such as Candida species. However, it is uncertain whether acetaldehyde concentration in human breath is related to oral condition or local production of acetaldehyde by oral microflora. The aim of this...

Before new treatment concepts can be used in daily practice, a critical analysis of the present scientific literature is necessary. The concept of full-mouth disinfection (FMD) was introduced as a new alternative treatment for the non-surgical therapy of inflammatory periodontal diseases, and is becoming more and more popular in dental practice. The following article provides a short survey and...

Context Local administration of antimicrobial agents offer a "site-specific" approach to the periodontal therapy and it has several benefits. Aim The present study was aimed to assess the clinical and microbial changes by subgingival irrigation using different subgingival irrigants in periodontitis patients and also to assess the mechanical effect of different local irrigation devices; if any...

BACKGROUND Type 2 diabetes mellitus (T2DM) is prevalent in people with obesity. It has been proposed that these conditions are related to specific features of the microflora of the mouth and lower gastrointestinal (GI) tract. Hyperglycemia often resolves quickly after Roux-en-Y gastric bypass (RYGB) but the role of the GI microflora cannot be examined easily because of reduced intestinal mobili...

We present bacterial biogeography as sampled from the human gastrointestinal tract of four healthy subjects. This study generated >32 million paired-end sequences of bacterial 16S rRNA genes (V3 region) representing >95,000 unique operational taxonomic units (OTUs; 97% similarity clusters), with >99% Good's coverage for all samples. The highest OTU richness and phylogenetic diversity was found ...

Starches are important as energy sources for humans and also for their interactions with the gut microflora throughout the digestive tact. Largely, those interactions promote human health. In the mouth, less gelatinised starches may lower risk of cariogensis. In the large bowel, starches which have escaped small intestinal digestion (resistant starch), together with proteins, other undigested c...

BACKGROUND To evaluate the antimicrobial activity of lidocaine (LD) topical anesthetic spray against oral microflora. METHODS Antimicrobial effects of 10% LD spray were assessed against six bacterial cultures obtained from volunteers: Escherichia coli, Enterococcus faecalis, Staphylococcus aureus, Streptococcus salivarius, Streptococcus pyogenes, and Streptococcus sanguinis. The filter papers...

Lactobacillus and bifidobacterial cultures are increasingly used as probiotics in pharmaceuticals and in foods. The selection of strains is performed often for technological rather than for microecological reasons. Detailed reports about species and strains composition of these microorganisms in the intestinal microflora of man are rare. Our investigations were performed with samples originatin...

OBJECTIVE To evaluate the effect of a mouth-rinse formulation combining benzydamine hydrochloride and cetylpyridinium chloride (BNZ+CPC) in preventing de novo plaque formation, in comparison with CPC and placebo mouth rinses. PATIENTS AND METHODS This was a controlled, observer-blind, cross-over study. In this model of plaque re-growth, subjects received a session of oral prophylaxis and were...
