Obesity is a pandemic which has been rapidly developing for three decades. When a population is submitted to the same nutritional stress, some individuals are less susceptible to diet-induced weight gain and hyperglycemia. This observation suggests that other mechanisms are involved which are not directly related to the human genome. The human gut contains an immense number of microorganisms, c...

Mosquito midgut plays a crucial role in its vector susceptibility and pathogen interaction. Identification of the sustainable microflora of the midgut environment can therefore help in evaluating its contribution in mosquito-pathogen interaction and in turn vector competence. To understand the bacterial diversity in the midgut of Aedes aegypti mosquitoes, we conducted a screening study of the g...

The human bowel is host to a diverse group of bacteria with over 500 different bacterial species contributing to this diversity. Until recently these bacteria were regarded as residents without any specific functions. The last two decades have seen a radical change in our understanding of the interactions between the gut flora and their eukaryotic hosts and there is a growing appreciation of th...

There's evidence to suggest that probiotics, prebiotics, and a high-fiber diet can help mange various illnesses. Here's how to translate gut flora research into practice.

The microbiota of the human large intestine influences health and well-being. Whereas it has long been accepted that gut bacteria play a role in host pathogenesis, current opinion is that certain microflora components can have beneficial effects on gastroenteritis resistance, blood lipids, antitumor properties, lactose tolerance, and gastrointestinal immunity. It is postulated that in the infan...

Obesity and insulin resistance are the major predisposing factors to comorbidities, such as Type 2 diabetes, nonalcoholic fatty liver disease, cardiovascular and neurodegenerative diseases, and several types of cancer. The prevalence of obesity is still increasing worldwide and now affects a large number of individuals. Here, we review the role of the gut microbiota in the pathophysiology of in...

Bacterial distribution in different developmental stages of house fly Muscadomesticavicina revealed that in the majority of maggots and prepupae, the hemolymph is sterile. Fat cells and trachea are like-wise sterile. Bacteria was distributed through the digestive tract of immature stages of the fly. In larvae/ the largest bacterial count was found in the fore gut then the hind gut and lastly th...

In a young evolving science, there are always more questions than answers. That is also the situation in the emerging field of Probiotics, and this was made very clear at the International Probiotics Workshop in Amsterdam. In the report of this workshop, we present a selection of the most urgent questions in the field of probiotics. In addition, we propose a few strategies for the future of pro...

Commensal microorganisms are not ignored by the intestinal immune system. Recent evidence shows that commensals actively participate in maintaining intestinal immune homeostasis by interacting with intestinal epithelial cells and delivering tolerogenic signals that are transmitted to the underlying cells of the immune system.

Emerging data indicate that humans enjoy health through a productive collaboration with their colonizing flora, the majority of whom reside in the colon. This minireview provides a perspective on recent data and the exciting scientific challenges ahead.
