Probiotics have been demonstrated to be useful to enhance gut health and prevent gastrointestinal infections in humans. Additionally, some multi-strain probiotic combinations have been suggested to have greater efficacy than single strains. The objective of this study is to demonstrate the potential of a combination of the probiotic strains: Bifidobacterium longum subsp. infantis CECT 7210 (bra...

This experiment was conducted to compare the effects of multi-strain probiotic inclusion levels on performance, intestinal morphology, gut microflora and hematological changes in Salmonella typhimurium (ST) infected broiler chickens. A total of 120 day old Ross 308 broiler chickens were distributed into 20 floor pens and reared for 10 days under 5 experimental treatments including a corn-soy ba...

The gastrointestinal tract of human body is considered as an ecosystem which had been developed physiologically and microbiologically. The probiotic organisms (lactic acid bacteria) are one of the most important groups present in the gastrointestinal tract. A good number of Lactobacillus species, Bifidobacterium species, Saccharomyces boulardii and some other microbes are now used as probiotic ...

Background/Aims Visceral pain and hypothalamic-pituitary-adrenal axis (HPA) dysregulation is a common characteristic in irritable bowel syndrome (IBS) patients. Previously, we reported that a probiotic formulation (Lactobacillus helveticus R0052 and Bifidobacterium longum R0175) prevents chronic stress-mediated brain function abnormalities by attenuating the HPA axis response. Here, we compared...

A probiotic containing Bacillus mesentericus, Clostridium butyricum, and Streptococcus faecalis [AVITEAM] was evaluated in damage control and synergism with vaccination against coccidial infection in broilers, using morphometric measurements and histopathological observations. It was mixed in feeds and vaccination was done by inoculating birds with an attenuated live vaccine containing Eimeria ...

Alzheimer's disease (AD) is associated with severe cognitive impairments as well as some metabolic defects. Scant studies in animal models indicate a link between probiotics and cognitive function. This randomized, double-blind, and controlled clinical trial was conducted among 60 AD patients to assess the effects of probiotic supplementation on cognitive function and metabolic status. The pati...

Notwithstanding the European Food Safety Authority (EFSA) did not approve any health claims for probiotic foods [including terms such as " probiotic, " " active bacteria " ; European Commission (EC), 2007], most of the research studies in the field of microorganisms used for obtaining functional food deal with (putatively) probiotic bacteria. Probiotics may positively affect human/animal health...

A need has existed for a selective medium that allows for growth of Bacillus anthracis while inhibiting common contaminants and closely related sporeformers (e.g., B. cereus). A selective medium (PLET medium) was developed containing the following ingredients added to Difco Heart Infusion Agar (HIA): polymyxin, 30 units/ml; lysozyme, 40 ,ug/ml; disodium ethylenediaminetetraacetate (EDTA), 300 ,...

Bacteria resistant to cadmium or mercury or both were isolated from the Great Sippewissett Marsh (Cape Cod, Mass.) and from Boston Harbor. Many of these metal-resistant isolates were gram-positive aerobic sporeformers, although not necessarily isolated as spores. Although several of the isolated strains bore plasmids, cadmium and mercury resistances appeared to be, for the most part, chromosoma...

The use of probiotic products, especially for humans, requires an unequivocal taxonomical definition of their microbial content, in order to assign the probiotic effects to well identified and characterized microbial strains. In the absence of this, the labeling of some marketed probiotics may be misleading, both in terms of microbiological contents and possible beneficial effects. Currently, t...
