Bacillus cereus strain F, collected from relict permafrost located in Siberia, was analyzed for probiotic activity in the mouse Salmonella enterica model. Viable bacterial cells were found in frozen soils taken at Mammoth Mountain in Yakutia from a depth below the level of seasonal thawing. Geological data indicated the absence of a thawing within millions of years of deposited soils, which hel...

Two previously isolated Lactobacillus strains (L. fermentum HM3 from human milk and L. buchneri FD2 from fermented dates), intended as probiotic for human, were assessed for their safety using acute and subacute oral toxicity tests in rats. In addition, their effects on cecal microflora and harmful bacterial enzymes (β-glucuronidase and β-glucosidase) of the tested animals were also determined....

Probiotics have been found to be beneficial to host health. In medicine, probiotics are used mainly in support therapy for gastro-intestinal diseases. In recent years, probiotics have been used as a treatment to promote oral health. There has also been a change in understanding of the oral disease process because of better understanding of the ecology and microbiology of the oral cavity. Very e...

UNLABELLED Growing evidence shows that gut microbes are key factors involved in the regulation of energy homeostasis, metabolic inflammation, lipid metabolism, and glucose metabolism. Therefore, gut microbiota modulations caused by selectively fermented oligosaccharides or probiotic bacteria constitute an interesting target in the physiopathology of obesity. However, to date, no probiotic yeast...

Influenza A(H1N1)pdm virus caused the first human pandemic of the 21st century. Although various probiotic Lactobacillus species have been shown to have anti-microbial effects against pneumonia-inducing pathogens, the prophylactic efficacy and mechanisms behind their protection remain largely unknown. Here, we evaluated the prophylactic efficacy of heat-killed Lactobacillus pentosus b240 agains...

ORAL PRESENTATIONS a mix survived differently in individual animals and in general, the culture combination resulted in good survival and persistence, as previously observed by Pedersen et al. (1992). Many studies have reported reductions in intestinal coliform and Enterobacteriaceae due to probiotic administration; however, some have seen no effects (Simon et al., 2003). In the present study m...

Lactobacillus plantarum DK119 (DK119) isolated from the fermented Korean cabbage food was used as a probiotic to determine its antiviral effects on influenza virus. DK119 intranasal or oral administration conferred 100% protection against subsequent lethal infection with influenza A viruses, prevented significant weight loss, and lowered lung viral loads in a mouse model. The antiviral protecti...

Background: Oral infections caused by microorganisms have led to increased risk of oral health problems like dental caries (DC). Streptococcus mutans and Candida albicans are the organisms responsible for DC. The goal presented study was investigate potential probiotics prevent treat An in vitro assay developed several probiotic strains their ability inhibit aforementioned pathogens. Methods: 4...

There is now increasing evidence that probiotic bacteria can provide health benefits to humans. In many areas of medicine (gastroenterology, urology, allergology, oncology and others), these sanative microorganisms may be considered as possible and viable alternatives applicable to patient care. Particularly, we have found that oral administration of Bacillus oligonitrophilus KU-1 cells can be ...

Most common forms of infections are caused by oral diseases. The use of higher dose of antibiotics has resulted in the development of resistant subgingival microbiota in adult periodontitis patients. New methods such as probiotic approaches to eliminate pathogenic microbiota can be investigated. Probiotics are one of the newly introduced agents widely used for therapeutic action i.e. whole bact...
