Probiotic ingestion can be recommended as a preventative approach to maintaining the balance of the intestinal microflora and thereby enhance 'well-being'. Research into the use of probiotic intervention in specific illnesses and disorders has identified certain patient populations that may benefit from the approach. Undoubtedly, probiotics will vary in their efficacy and it may not be the case...

The impressive variety of reactions that can be performed by the gut flora on both exogenous and endogenously-produced compounds justifies its status as a major site of metabolism, comparable to the liver (Drasar et al. 1970; Scheline, 1973; Walker, 1973; Drasar & Hill, 1974). Furthermore, one might expect that the capacity of the flora to adapt to metabolic pressure by altering its component o...

The colonization of the infant gut after birth represents a complex succession of bacterial types and is governed by a wide range of external influences such as the mother’s vaginal, faecal and skin floras, the extent of bacterial contamination of the perinatal environment and the feeding regime. The influence of breast feeding and formula feeding on the development of the infant gastrointestin...

The intestinal lactic acid microflora of the edible snail Cornu aspersum was studied by culture-based methods and was phenotypically and molecularly characterized. The antibacterial activity of lactic acid bacteria (LAB) isolates was investigated. Snails in different stages of development were collected from farms located in several regions of Bulgaria. One hundred twenty-two isolates, belongin...

PURPOSE OF REVIEW Gut microbiota plays an important role in health and disease, but this ecosystem remains incompletely characterized and shows a wide diversity. This review discusses new findings that may explain how gut microbiota can be involved in the control of energy and metabolic homeostasis. RECENT FINDINGS Over the past 5 years studies have highlighted some key aspects of the mammali...

Several dietary phytochemicals exhibit anti-oxidative, anti-inflammatory and anti-osteoporotic activities relevant to prevention of chronic diseases, including lifestyle-related diseases. Soybean isoflavones are similar in structure to estrogen and have received considerable attention as potential alternatives to hormone replacement therapy. Daidzein, a major isoflavone found in soybean, is met...

The birth process allows the progressive formation of complex intestinal microflora composed of myriad bacteria, leading to this recently identified host-bacterial mutualism in the human intestine. This kind of cross-talk originating from birth is opportunistically used by the young host to initiate its own immune system. Recent epidemiogical data support the hypothesis that some increasing imm...

The gut microflora is an important constituent in the intestinal mucosal barrier and has been introduced as the concept of probiotic therapy that beneficially affects the host by improving its intestinal microbial balance. Therefore, the main objective of the study was to explore the protective potential of various lactobacilli strains for murine giardiasis. By experimentation, it was found tha...

Toll-like receptors (TLRs) play a crucial role in host defense against microbial infection. The microbial ligands recognized by TLRs are not unique to pathogens, however, and are produced by both pathogenic and commensal microorganisms. It is thought that an inflammatory response to commensal bacteria is avoided due to sequestration of microflora by surface epithelia. Here, we show that commens...
