In an in vitro experiment commercially available probiotic products were tested for the survival of bacteria under conditions of simulated human digestion either when used alone or mixed into yogurt. In the in vivo experiment the effects of feeding a whey- and milk-based yogurt prepared with the probiotic strain showing adequate survival in the in vitro experiment, was measured on body weight, ...

The production of fatty acids in cream containing one of the three probiotic microorganisms (Bifidobacterium lactis, Lactobacillus acidophilus and Lactobacillus rhamnosus) was evaluated at 4±1 °C for up to 15 days. Gas chromatographic analysis of the fatty acid content showed that during storage the amount of linoleic and α-linolenic acids increased in the probiotic cream fermented with B. lact...

Background & Aims: Probiotic bacteria have beneficial effects on host's health. However, one of the most important reasons which affect the probiotic activity of a microorganism is its survival during the gut transit. Microencapsulation techniques could be applied to bacteria to improve this parameter. Methods: In this study, feces of 60 healthy volunteers were analyzed during 28-day test perio...

the aim of this study was to determine the suitability of different doses (0, 0.4, 0.8 and 1.2%) of coffee extract on fermentation and survival of lactobacillus acidophilus and bifidobacterium bifidum in milk and yoghurt. the produced samples were examined in terms of ph, acidity and microbial count during incubation period and permanence. the number of lactobacillus acidophilus and bifidobacte...

Unheated and heat-treated homogenates were separately prepared from candidate probiotic bacteria, including Lactobacillus rhamnosus GG, Bifidobacterium lactis, Lactobacillus acidophilus, Lactobacillus delbrueckii subsp. bulgaricus, and Streptococcus thermophilus. We compared the phytohemagglutinin-induced proliferation of mononuclear cells in the presence of homogenates and in the presence of a...

AIM : Although numerous animal studies suggest that probiotic therapy has beneficial effects in various liver diseases, the evidence for beneficial effects in human liver disease is controversial. This study was carried out to investigate the efficacy of probiotic therapy in alleviating small intestinal bacterial overgrowth (SIBO) and permeability in chronic liver disease. METHODS Fifty-three...

Helicobacter pylori is a human pathogen that infects over 50% of the population worldwide. It is the most important etiologic agent of gastroduodenal ulcers and malignancies. Helicobacter pylori urease enzyme is considered the main factor for the organism's colonization in the gastroduodenal mucosa. Hens immunized with the purified urease produce a highly specific anti-H. pylori urease immunogl...

BACKGROUND Alteration in plasma lipid and lipoprotein profile has been documented in diabetic patients. The purpose of this study was to compare the effect of probiotic and conventional yogurt on lipid profile in type 2 diabetes mellitus patients. MATERIALS AND METHODS A total of 44 patients with type 2 diabetes aged 30-60 years old who had low density lipoprotein cholesterol (LDL-c) ≥100 mg/...
