Bifidobacteria are predominant in the lumen of the large intestine and confer various health benefits on the host. They are also used in the preparation of new fermented milks (bioyogurts) or added to conventional yogurt to generate probiotic effects. The colonization of the gut by bacteria tends to be host specific due partly to the way in which bacteria adhere to the intestinal wall. Using a ...

Lactobacilli are generally regarded as safe; however, certain strains have been associated with cases of infection. Our workgroup has already assessed many functional properties of Lactobacillus kefiri, but parameters regarding safety must be studied before calling them probiotics. In this work, safety aspects and antimicrobial activity of L. kefiri strains were studied. None of the L. kefiri s...

nowadays, people tend to consume functional foods for the treatment and prevention of diseases. production growth of functional foods obliged scientists to research about production, distribution and preservation conditions of these products. use of probiotic microorganisms in soy-based products may have advantages of both probiotics and soy on the human health. the probiotic soy-based ice-crea...

an experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, cyprinus carpio. four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % biogen probiotic were used to feed fish. seventy-two juvenile common carp (65 ? 3.5g) were randomly distributed between 12 fiberglass tanks of 500 l capacity. during 60 days of feeding trial, the...

This study was carried out to determine the effects of adding probiotics and ginger (Zingiber officinale) broiler rations on growth performance, carcass parameters meat quality parameters. In study, 396 Ross 308 male female chickens were used as animal material. The chicks divided into 6 groups with replicates each containing 11 animals. prepared by control, 0.3%ginger, 0.6%ginger, 0.05%probiot...

Allergy is one of the most important and very common health problems worldwide. To reduce the proportion of people suffering from allergy, alternative methods of prevention and treatment are sought. The aim of this paper is to present the possibilities of probiotics in the prevention and treatment of allergic diseases. Probiotics are live microorganisms belonging mainly to the lactic acid bacte...

Clinical observations and epidemiologic studies suggest that the incidence of head and neck squamous cell carcinoma (HNSCC) correlates with dental hygiene, implying a role for bacteria-induced inflammation in its pathogenesis. Here we begin to explore the pilot hypothesis that specific microbial populations may contribute to HNSCC pathogenesis via epigenetic modifications in inflammatory- and H...

OBJECTIVE To investigate the functional effects of probiotic treatment on the gut microbiota, as well as liver and adipose gene expression in diet-induced obese mice. DESIGN Male C57BL/6J mice were fed a high-fat diet (HFD) for 8 weeks to induce obesity, and then randomized to receive HFD+probiotic (Lactobacillus curvatus HY7601 and Lactobacillus plantarum KY1032, n = 9) or HFD+placebo (n = 9...

Intestinal epithelial cells are the targets for transmissible gastroenteritis (TGE) virus (TGEV) infection. It is urgent to develop a novel candidate against TGEV entry. Bacillus subtilis is a probiotic with excellent anti-microorganism properties and one of its secretions, surfactin, has been regarded as a versatile weapon for most plant pathogens, especially for the enveloped virus. We demons...

The link between gut microbiota and human health is well-recognized and described. This ultimate impact on the host has contributed to explain the mutual dependence between humans and their gut bacteria. Gut microbiota can be manipulated through passive or active strategies. The former includes diet, lifestyle, and environment, while the latter comprise antibiotics, pre- and probiotics. Histori...
