Molecular Characterization of Intestinal Bacteria in Healthy Cats and a Comparison of the Fecal Bacterial Flora between Healthy Cats and Cats with Inflammatory Bowel Disease (IBD). (August 2008) Lauren Elizabeth Ritchie, B.S., Texas A&M University Co-Chairs of Advisory Committee: Dr. Jan S. Suchodolski Dr. Jörg M. Steiner Past studies characterizing the feline intestinal microflora have used tr...

The inflammatory bowel diseases (IBD), Crohn's disease and ulcerative colitis, are T cell-mediated diseases that are characterized by chronic, relapsing inflammation of the intestinal tract. The pathogenesis of IBD involves the complex interaction between the intestinal microflora, host genetic and immune factors, and environmental stimuli. Epidemiological analyses have implicated acute bacteri...

Probiotics are beneficial live microorganisms because they provide health benefits to the host after being consumed in sufficient amounts, primarily by increasing proliferation of native digestive microflora. Hypercholesterolemia is a condition which cholesterol serum concentration elevated significantly (exceeds 200 mg/dL). characterized high plasma levels low-density lipoprotein (LDL) and low...

Lactobacilli and bifidobacteria are important members of the gastrointestinal microflora of man and animals. There is a substantial and growing body of evidence that these microbes provide benefits to the host in which they reside. Understanding the roles of these two groups of bacteria in the intestine continues to be a significant challenge. To this end, genetic characterisation and manipulat...

Signaling by lymphotoxin (LT) and TNF is essential for the organogenesis of secondary lymphoid tissues in systemic and mucosal compartments. In this study, we demonstrated that the progeny of mice treated with fusion protein of LTbetaR and IgGFc (LTbetaR-Ig) or LTbetaR-Ig plus TNFR55-Ig (double Ig) showed significantly increased numbers of isolated lymphoid follicles (ILF) in the large intestin...

Aim. To study the opinions of gastroenterologists about drugs affecting intestinal microflora.
 Materials and methods. A qualitative survey was conducted in focus groups to patterns prescribing that regulate microflora chronic gastrointestinal diseases. The included only outpatient who managed patients with irritable bowel syndrome, an uncomplicated diverticular disease clinical manifestat...

For 4 weeks, 3-month old germfree (GF) and conventional (CV) rats were given a semi-synthetic diet sterilized by irradiation with or without 10% of lactose. During the 5th week, 0.2% of titanium oxide (TiO2) was added to the diet and the rats were killed at regular intervals throughout the light/dark cycle. The patterns of TiO2 and 45Ca excretion were similar, indicating that TiO2 was a good ma...

Samples from the pharynx, stomach, duodenum or jejunum, and faeces were collected on 7 days between 1st and 28th day from neonates weighing less than 1.5 kg at birth who were fed by transpyloric tube. These were cultured on selective and non-selective media, and the results were expressed in a semi-quantitative manner. The number of bacterial species and the density of their growth increased wi...

The effects of diet on the histochemical composition of intestinal mucosubstances and the morphology of the villi and crypts were investigated by comparing the data of germ free and conventionally maintained rats fed either a purified diet or a commercial diet. The influence of intestinal microflora was evaluated by comparing the germ free rats and those harbouring either a conventional rat flo...

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...
