Segmented filamentous bacteria (SFBs) are apathogenic autochthonous bacteria in the murine small intestine that preferentially attach to Peyer's patch epithelium. SFBs have never been cultured in vitro. We have studied the effects of SFBs on the immune system of the host. Mice monoassociated with SFBs were compared with germ-free mice and with mice without SFBs but with a specific-pathogen-free...

The normal bacterial flora contains antibiotic resistance genes to various degrees, even in individuals with no history of exposure to commercially prepared antibiotics. Several factors seem to increase the number of antibiotic-resistant bacteria in feces. One important factor is the exposure of the intestinal flora to antibacterial drugs. Antibiotics used as feed additives seem to play an impo...

introduction: nosocomial infections affect nearly 10% of hospitalized patients. the majority of nosocomial infections are transmitted by contact, primarily by hands of health care workers. the micro-organisms on the hand can be divided into transient, resident and infectious flora. transient flora is the main cause of nosocomial infection which acquired primarily by contact and loosely attached...

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...

The aim of this study was to count, isolate and identify by traditional methods the major bacteria colonizing the intestinal tract of organic and conventional chickens. The study was performed in 2 conventional and 2 organic chicken farms. Intestinal samples (24 from ileum and 24 from caecum) were collected from organic reared chickens during the production cycle (40 days of age) and at slaught...

The isolated and identified bacteria from yoghurt sample are of spp. Lactobacillus. The bacteria of this spp. are lactic acid producers. These spp. resembles to Lactobacillus acidophilus. A probiotic is a microorganism known to be friendly and beneficial to its host when consumed. In today's time, probiotics are a very popular subject of research among scientists and pharmaceutical companies .D...

Spirulina is a photosynthetic, filamentous, spiral-shaped and multicellular edible microbe. It is the nature's richest and most complete source of nutrition. Spirulina has a unique blend of nutrients that no single source can offer. The alga contains a wide spectrum of prophylactic and therapeutic nutrients that include B-complex vitamins, minerals, proteins, gamma-linolenic acid and the super ...

Nutritional practices that promote good health and optimal athletic performance are of interest to athletes, coaches, exercise scientists and dietitians. Probiotic supplements modulate the intestinal microbial flora and offer promise as a practical means of enhancing gut and immune function. The intestinal microbial flora consists of diverse bacterial species that inhabit the gastrointestinal t...
