Digesta Passage, Fermentation, and Microbes in the Hindgut and Its Relative Contribution to the Nutrition of Cattle
Fermentation in the cecum and colon and digesta passage through the intestines were investigated in a series of experiments. Specific gravity, but not length, of inert particles affected their passage through the intestines. Passage was quickest for particles with a specific gravity of 1.17 and …

Microbiome Dynamics in Broilers Infected with Infectious Bronchitis Virus and the Protective Role of Lactobacillus-Based Probiotics
… in IBV challenged group compared to control in cecum at 6 and 15 dpi, whereas tracheal microbiome of IBV challenged group showed significantly higher evenness and Shannon index compared to control in 6 and 9 dpi respectively. Beta diversity indicated a significant microbial composition shift in …

The Role of Microbiota in Formation and Bioavailability of Sulforaphane From Glucoraphanin in F344 Rats
In conclusion, the cecum in the rat is the major site of fermentation by microbiota. Since the colon is right next to the cecum, colonic NQO1 induction as well as cecal inflammation indicate that cecal microbiota may play an important role in the hydrolysis to bioactive SF from GRP. However, the …

Response of large intestinal mucosa in rats to dietary protein and fat
… ammonia concentrations of the contents in the cecum and different segments of colon in rats fed defined semi-purified diets and (2) to determine if the pH and ammonia concentrations of the cecal and colon contents are associated with differences in mucosal cell proliferation of the cecum and …

Nutritional implications of coprophagy and cecal function in two microtine rodents (Microtus pennsylvanicus and Microtus pinetorum)
… protein intake under these dietary conditions. Cecum removal decreased diet digestibility but did not significantly influence body weight dynamics since food consumption and passage rate increased to compensate for the digestibility perturbations induced by cecectomy. However, the effects of …

Molecular Analysis of Roseburia Cecicola, a Motile Anaerobe, as a Foundation for Study of Bacterial Motility and Chemotaxis in the Murine Gastrointestinal Ecosystem
… to colonize its specific habitat in the mouse cecum. I purified the main protein (flagellin) of the flagellar apparatus of the organism. The purified protein was then used in raising polyclonal and monoclonal antibodies. In addition, the gene encoding the protein was cloned and sequenced.

Molecular analysis of oxygen toxicity in the obligate anaerobe Roseburia cecicola: Isolation of a compound that degrades DNA when exposed to oxygen
… bacterium isolated from the mucosa of the murine cecum, Roseburia cecicola. This organism is a strict anaerobe whose growth is inhibited when exposed to oxygen.

Pathological Changes and Immunity Associated With Experimental Eimeria Vermiformis Infections in the Mouse (Mus Musculus)
… changes were studied in the small intestine, cecum, colon, mesenteric lymph nodes, liver, spleen and kidney. Surface changes in ileum were studied with the scanning electron microscope (SEM). Immunity to E. vermiformis was determined 30 and 105 DAI. Cross-immunity to E. ferrisi was also …

The invasin IbeA and its role in Adherent-Invasive Escherichia coli (AIEC) pathogenesis
… pathology scores in the small intestine and the cecum for AIEC ∆ibeA when compared to the wild-type, and reduced IFN-γ secretion in the cecum. This study reports, for the first time, the role of the invasin IbeA in the AIEC pathotype, and shows that it plays a relevant role not only in the …

Development of an antigen-specific ELISPOT to detect intestinal antibody responses to the swine whipworm, Trichuris suis
… jejunal region of small intestine (SI-MLN) and cecum in large intestine (C-MLN); and ileocecal Peyer's patches (IC-PP)] and lamina propria from the proximal colon removed from T. suis infected pigs. Tbe local antibody responses were compared to peripheral antibody responses found in the spleen …

Butyrate-induced upregulation of intestinal glucose transport and signaling pathways represent a possible nutrient therapy for individuals with malabsorptive disorders
… for GLP-1 and GLP-2) was 2-fold higher in the cecum of butyrate-treated rats (P<0.0014). Butyrate also increased FFAR2 and FFAR3 mRNA abundance in the cecum. Taken together, butyrate increased glucose transport by the proximal intestine supported by an increase of jejunal GLUT2 and stimulation …

CHARACTERIZING THE ROLE OF PUTATIVE VIRULENCE GENES ASSOCIATED WITH INFECTION, COLONIZATION AND PERSISTENCE OF SALMONELLA ENTERITIDIS IN CHICKEN USING A BIOLUMINESCENT REPORTER
… early as 30 hours post-infection (p.i.) in the cecum with the aid of photonic signal strength detected by ex-vivo imaging and colony count values. Thus, colonization in the cecum is a rapid process in young birds. Other predilection sites were the crop and yolk sac, which were colonized at 24 …

Optimization and Application of Metabolomic Assays for Analyzing Diet-induced and Gut Microbiota-derived Short-chain Fatty Acids in Mice and Humans
… This method was also retrospectively applied to cecum samples of KK.Cg-A<sup>y</sup>/a, genetically induced obese mouse model, to quantify the effects of RS4 on cecum SCFA concentrations. 16S rRNA sequencing was performed to study the effect of RS4 on gut microbial composition. Blood biomarkers, …

Characterizing the microbiota and profiling small non-coding RNAs in the compartments of the equine hindgut
… the microbial population structure within the cecum, right ventral colon, right dorsal colon and feces. First, we characterized microbial communities present in each of these anatomical sites and then completed a multivariate model to determine similarities of compartments and compared those to …

The effects of administered indigenous micro-organisms on uptake of ¹²⁵I-gamma globulin in in vitro intestinal segments of neonatal calves
… was expressed as percentage of distance from cecum to abomasum. Uptake was expressed as milligrams gamma globulin internalized per gram of segment tissue. Distribution of gamma globulin uptake after 1.5 h exposure was a cubic function of PSEG. Uptake was greatest In a region 15% of …

Select novel carbohydrates affect glycemic and insulinemic response, energy value, and indices of gut health as measured using canine, avian, rodent, and in vitro model systems
… cecal weight but not colon weight. On a per cecum basis, SFD and SCF increased acetate, propionate, and total SCFA concentrations, with no effect on butyrate concentrations, compared to the Control diet. Cecal branched-chain fatty acids (BCFA) concentrations were decreased by SFD and SCF, …

The effects of 2’-fucosyllactose and Bifidobacterium longum subspecies infantis supplementation on growth, intestinal development and immune development and function in piglets
… disaccharidase activity. Luminal samples from cecum, ascending colon (AC) and rectum (RC) were analyzed for dry matter. Volatile fatty acids (VFA) and abundance of Bifidobacterium ssp. and B infantis, analyzed by qPCR were measured in AC and RC contents. There was no experimental treatment …
