Hemorrhagic enteritis (HE) is an acute viral disease that affects avian species, particularly turkeys, compromising their commercial production and having a negative effect on animal welfare. Turkey adenovirus 3 (TAdV-3), is the main causal agent of the disease. In this study, we considered 3 groups of turkeys to achieve 2 purposes: 1) A preliminary investigation on the microbiota content in the 4 parts of healthy turkey's intestine (group A), namely duodenum, jejunum, ileum, and ceca was done; 2) an investigation on the relationship between natural infections with TAdV-3 and the intestinal microbiota in the jejunum, where HE mostly develops, comparing group A with animals with molecular positivity for the virus and with clinical signs of HE (group B) and animals with molecular positivity for the virus but without clinical signs (group C)...

Although the intestine plays the major role in 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) action on calcium homeostasis, the mechanisms involved remain incompletely understood. The established model of 1,25(OH)2D3 regulated intestinal calcium absorption postulates a critical role for the duodenum. However it is the distal intestine where 70 -80% of the ingested calcium is absorbed. In order to test directly the role of 1,25(OH)2D3 and the vitamin D receptor (VDR) in the distal intestine, 3 independent knockout (KO) /transgenic (TG) lines expressing VDR exclusively in the ileum, cecum and colon were generated by breeding VDR KO mice with TG mice expressing human (h)VDR under the control of the 9...

Hemorrhage following whole-body γ-irradiation in a combined injury (CI) model increases mortality compared to whole-body γ-irradiation alone (RI). The decreased survival in CI is accompanied by increased bone marrow injury, decreased hematocrit, and alterations of miRNA in the kidney. In this study, our aim was to examine cytokine homeostasis, susceptibility to systemic bacterial infection, and intestinal injury. More specifically, we evaluated the interleukin-6 (IL-6)-induced stress proteins including C-reactive protein (CRP), complement 3 (C3), Flt-3 ligand, and corticosterone...

Intestinal cells can sense the presence of pathogens and trigger many important signaling pathways to maintain tissue homeostasis and normal function. Escherichia coli and lipopolysaccharides (LPS) are the main pathogenic factors of intestinal disease in pigs. However, the roles of endoplasmic reticulum stress (ERS) and its mediated apoptosis in intestinal malfunction induced by E. coli or LPS remain unclear. In the present study, we aimed to evaluate whether ERS could be activated by E. coli fed to piglets and whether the underlying mechanisms of this disease process could be exploited...

Ileocolic resection (ICR) is the most common intestinal resection performed for Crohn's disease, with recurrences commonly occurring at the site of the anastomosis. This study used an animal model of ICR in wild-type mice to examine immunologic changes that developed around the surgical anastomosis and how these changes impacted gut responses to minor acute injury. ICR was performed in adult 129S1/SvlmJ mice and results compared with mice receiving sham or no surgery. Dextran sodium sulfate was given either on post-operative day 9 or day 24 to evaluate immune responses in the intestine both immediately following surgery and after a period of healing...

Dacomitinib, an irreversible small-molecule pan-ErbB TKI, has a high incidence of diarrhea which has been suggested to be due to chloride secretory mechanisms. Based on this hypothesis, crofelemer, an anti-secretory agent may be an effective intervention. T84 monolayers were treated with 1µM dacomitinib and 10µM crofelemer, and mounted into Ussing chambers for electrogenic ion analysis. Crofelemer attenuated increases in chloride secretion in cells treated with dacomitinib. Albino Wistar rats (n=48) were treated with 7...

Currently, the screening of new drug candidates for intestinal permeation is typically based on in vitro models which give no information regarding regional differences along the gut. When evaluation of intestinal permeability by region is undertaken, two preclinical rat models are commonly used, the Ussing chamber method and single-pass intestinal perfusion (SPIP). To investigate the robustness of in vivo predictions of human intestinal permeability, a set of four model compounds was systematically investigated in both these models, using tissue specimens and segments from the jejunum, ileum, and colon of rats from the same genetic strain...

Inadequate feed consumption reduces intestinal barrier function in both ruminants and monogastrics. Objectives were to characterize how progressive feed restriction (FR) affects inflammation, metabolism, and intestinal morphology, and to investigate if glucagon-like peptide 2 (GLP2) administration influences the aforementioned responses. Twenty-eight Holstein cows (157 ± 9 d in milk) were enrolled in 2 experimental periods. Period 1 [5 d of ad libitum (AL) feed intake] served as baseline for period 2 (5 d), during which cows received 1 of 6 treatments: (1) 100% of AL feed intake (AL100; n = 3), (2) 80% of AL feed intake (n = 5), (3) 60% of AL feed intake (n = 5), (4) 40% of AL feed intake (AL40; n = 5), (5) 40% of AL feed intake + GLP2 administration (AL40G; 75 µg/kg of BW s...

Tritrichomonas foetus (T. foetus) is a flagellated protozoa that infects the distal ileum and proximal colon of domestic cats, as well as the urogenital tract of cattle. Feline trichomonosis is recognized as a prevalent cause of chronic diarrhea in cats worldwide. The suspected route of transmission is fecal-oral, with cats in densely crowded environments at highest risk for infection. Thus, the recommended strategy for minimizing spread of infection is to identify and isolate T. foetus-positive cats from the general population...

BACKGROUND AND OBJECTIVES: In Crohn's disease (CD), belonging to inflammatory bowel disease, the small intestine is involved in most cases. Most frequently affected is the distal ileum, where vitamin B-12 is specifically absorbed. Therefore, malabsorption of vitamin B-12 is quite likely to occur in patients with CD. In this study, we have studied the vitamin B-12 status in CD patients. METHODS AND STUDY DESIGN: Forty eight patients with CD were evaluated for their food intake, and circulating concentrations of vitamin B-12, folic acid, and homocysteine (Hcy) as a sensitive marker for the insufficiency of these vitamins and a risk factor of atherosclerosis...

Short-term feeding with low-fiber diet remodels the mechanomorphological properties in the rabbit small intestine. The aims were to study the effect of feeding low-fiber diet for 5 months on mechanomorphological properties including the collagen fraction in the rabbit intestines. Fifteen rabbits were divided into an Intervention group (IG, n = 10) fed a low-fiber diet and a Control group (CG, n = 5) fed a normal diet for 5 months. Five months later, four 10-cm-long segments obtained from the duodenum, jejunum, ileum and large intestine were used for histological and mechanical analysis, respectively...
