Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, mainly through the process of replacing or including beneficial bacteria in the gastrointestinal tract. Fermented dairy foods such as yogurt, fermented milk and cheese are the major vehicle in delivering probiotics, and probiotic delivery have been traditionally associated with t...

D a t a s o u r c e s Studies were identified by searching MEDLINE, EMBASE/Excerpta Medica, the Cochrane Controlled Trials Register, DARE, and CINAHL from 1966 to 2000, and AMED, MANTIS, the Complementary and Alternative Medicine Citation Index, and AltHealthWatch from 1985 to 2000. Search terms used were diarrhea, gastroenteritis, or rotavirus combined with competitive inhibition, Lactobacillu...

In the present work, the effect of milk supplementation on viability of yogurt bacteria (Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus) and probiotic bacteria (Lactobacillus acidophilus and Bifidobacteria) was studied during yogurt manufacture and thirty three days storage. Incubation time to reach pH value of 4.5 was greatly affected by the addition of casein fract...

Lactic acid bacteria are among the most important probiotic microorganisms typically associated with the human gastrointestinal tract. Traditionally, lactic acid bacteria have been classified on the basis of phenotypic properties, eg, morphology, mode of glucose fermentation, growth at different temperatures, lactic acid configuration, and fermentation of various carbohydrates. Studies based on...

background and aim: yogurt is one of the most consumed foods with different probiotic effects. the aim of this study was to evaluate antimicrobial effects of non-industrial yogurts on two common enteropathogens – salmonella and shigella. methods: in this experimental study, we evaluated the antimicrobial effects of 30 various non-industrial yogurt samples on 11 shigella sonnei, 7 shigella flexn...

BACKGROUND We have previously reported the results of a randomized, double-blind, placebo-controlled trial that found the intake of yogurt supplemented with a probiotic strain, Bifidobacterium longum BB536, alleviates symptoms and affects blood parameters in individuals with Japanese cedar pollinosis (JCPsis) during the pollen season. OBJECTIVE In the present study, fecal microbiota were inve...

In this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. Milk inoculated with yogurt bacteria (mixed culture of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (L. acidophilus LA-5 or Bifidobacterium lactis Bb- 12 or L. rhamnosus HN001 or L. paracase...

Nowadays, there is an increasing interest in the production of functional foods, particularly probiotic foods. Lactic acid bacteria (LAB) particularly strains of Lactobacillus are important bacteria in food microbiology and human nutrition due to their ability to fermented food production and have received considerable attention as probiotics. The traditional fermented dairy foods as a rich sou...
