Germfree and conventional-flora Sprague-Dawley rats were fed sodium nitrate or sodium nitrite in their drinking water (1,000 microgram/ml), and various organs, tissues, and sections of the intestinal tract were assayed for nitrate (NO3-) and nitrite (NO2-) by a spectrophotometric method. When fed NO3-, germfree rats had chemically detectable levels of NO3- (only) in the stomach, small intestine...
introduction: bacterial translocation is defined as the passage of bacteria from intestinal tract to the extraintestinal organs such as the peritoneum and blood circulation. the aim of this study is to examine bacterial translocation (regarding type of bacteria and effect of time of obstruction on bacterial translocation) from intestinal lumen to the peritoneum and viscera in acute, simple mech...
Numerous investigations have been carried out dealing with the absorption of aureomycin into the blood stream, body fluids, and tissues (1, 2). However, no determination of the concentration of this antibiotic within the lumen of the intestine has been reported. Likewise, there have been many studies concerning the effect of oral aureomycin on the intestinal bacterial flora, but these have reli...
The alimentary canal may be regarded from the point of view of bacterial processes within it, as a singularly perfect incubator; an incubator in which there is provided at different levels such a range of reaction and diversity of food that not only are the conditions suitable for the growth of the normal habituated intestinal bacteria but often also for those organisms, capable of developing a...
The enterotoxaemia syndrome in Belgian Blue calves is characterised by a high case fatality rate, sudden death, lesions of haemorrhagic enteritis of the small intestine and, quite often an absence of other clinical signs but its cause has not been yet identified. As a first step in this identification, the aerobic and anaerobic intestinal flora of a population of 78 calves, originating from far...
Five patients with adult acquired hypogammaglobulinaemia, four of whom were achlorhydric, were studied. Jejunal bacterial counts were much higher than those in a control group of acid secretors, but were similar to those in a control group of patients with pernicious anaemia; Giardia lamblia were isolated from the jejunal content of all patients with hypogammaglobulinaemia. The concentration of...
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...
Obesity is currently a pandemic of worldwide proportions affecting millions of people. Recent studies have proposed the hypothesis that mechanisms not directly related to the human genome could be involved in the genesis of obesity, due to the fact that, when a population undergoes the same nutritional stress, not all individuals present weight gain related to the diet or become hyperglycemic. ...
The gut of a healthy adult harbours a myriad of different microbial species. It is estimated that approximately 10 14 are present in total bacterial colony forming units (CFU). Each colony colonizes a specific intestinal tract. In healthy adult, the main control of intestinal bacterial colonization occurs through gastric acidity but also other factors can influence the intestinal microenvironme...
