BACKGROUND/AIMS While probiotic bacteria are successfully used in the treatment of ulcerative colitis, the effect of commercially available probiotic products is still controversial. Here, we study whether the number of living probiotic bacteria in yoghurts is altered by an interruption of the cold chain. METHODS Three commonly available probiotic yoghurts were kept at 4°C or put at room temp...

OBJECTIVE To determine if local prophylactic application of probiotic bacteria to burn wounds will prevent death in a mouse model of burn wound sepsis. BACKGROUND Infection remains the most common complication after burn injury and can result in sepsis and death, despite the use of topical and systemic antibiotics. Pseudomonas aeruginosa is a frequently implicated pathogen. Local application ...

Domestic ruminants, especially sheep and cattle, are the main reservoirs of Shiga toxin-producing Escherichia coli (STEC) and may transmit this pathogen to human. Probiotics are "live organisms that, when administered in adequate amounts, confer a health benefit on the host", decreasing the infection and its dissemination. However, these benefits are conferred only after the colonization of pro...

The pathogenesis of Listeria monocytogenes depends on its ability to attach to and invade the gastrointestinal epithelium and subsequently withstand the host immune response. Despite a thorough understanding of the intracellular phase of infection, relatively little is known about how the pathogen behaves in the gastrointestinal tract and whether it is affected by the presence of host commensal...

Recently, high interest has been attracted to the research of inflammatory bowel diseases (IBD). Recombinant probiotic bacteria may represent an interesting way to influence the course of IBD. Their benefits include cheap and simple production and easy manipulation of the genetic material. Several gene therapy and probiotic approaches ...

Segmented filamentous bacteria (SFB) are present in the gastrointestinal tract of mice from weaning until the maturation of the immune system. Probiotic bacteria also have an effect on host immunity. To study the relationships established between these bacteria, samples from a mouse model fed with Lactobacillus plantarum under different immunological conditions were analysed. SFB populations we...

These lactic acid bacteria and probiotic microorganisms in fermented foods have been used for many years for health reasons and are now an attractive alternative for treating of intestinal disorders and seem to influence the immune system via stimulating protective immune cells. Through genetic engineering, it is possible to strengthen the effect of existing probiotic [8] strains and create com...

INTRODUCTION Human health is deemed to be maintained by the crosstalk among the body and probiotic bacteria. Disruptions in this composition are associated with the pathogenesis of numerous diseases. Through modernization, traditional foods consumption has been abandoned and native food starters have been substituted with industrial products. Hence, we aimed to isolate and evaluate probiotic ba...

The various therapeutic benefits of Lactobacillus acidophilus and Bifidobacterium spp. have resulted in their increased incorporation into dairy foods such as yoghurts. Currently however, the efficacy of these probiotic bacteria is limited by their poor survival during the shelf life of yoghurt. Oxygen toxicity is widely considered to be responsible for the cell deaths of these bacteria. The in...
