For ten years, a lot of advances have been achieved for the morphological exploration of the small intestine as well as with CT and MR enterography than with wireless capsule endoscopy. These investigations have renewed the approaches of different diseases that can affect the small intestine: tumors, especially sub-mucosal tumors (CT enterography), iron-deficiency anemia (capsule endoscopy) and follow-up of patients with Crohn's disease of the small intestine (MR enterography). Balloon enteroscopy may then allow therapeutic approach when needed (treatment of bleeding angiodysplasia).

An unusual case of small bowel obstruction (SBO) due to haemostatic gelatin sponge placed during caesarean delivery is presented. A primigravida in their 30s underwent caesarean delivery at 39 weeks, and developed symptoms of SBO from the second postoperative day. Given the worsening condition of the patient and increasing abdominal girth, CT of the abdomen and pelvis was done which revealed features of SBO.

Microbiota in the gastrointestinal tract (GIT) consisting of the rumen and hindgut (the small intestine, cecum and colon) in dairy calves play a vital role in their growth and development. This review discusses the development of dairy calf intestinal microbiomes with an emphasis on the impact that husbandry and rearing management have on microbiome development, health and growth of pre-weaned dairy calves. The diversity and composition of the microbes that colonize the lower GIT (small and large intestine) can have a significant impact on the growth and development of the calf, through influence on nutrient metabolism, immune modulation, resistance or susceptibility to infection, production outputs and behaviour modification in adult life.

Heat-stress-induced oxidative and inflammatory responses were important factors contributing to chicken intestinal damage. The purpose of this study was based on the antioxidant and anti-inflammatory activities of Physalis Calyx seu Fructus (Jin Deng Long, JDL) to investigate its efficacy and mechanism in relieving chicken heat stress damage. Primary chicken embryo duodenum cells and 90 30-day-old specific-pathogen-free chicken were randomly divided into control and JDL groups to establish heat stress models and .

Bacteria in the complex and nontuberculous mycobacteria may affect a variety of animal species under human care and pose public health risks as zoonotic pathogens. A case of sudden onset of lethargy and increased respiratory effort in a 5-y-old, intact female reindeer () under managed care had progressed to severe dyspnea despite aggressive treatment. The animal was euthanized due to poor prognosis.

Aims/hypothesis: Within the small intestine, neutrophils play an integral role in preventing bacterial infection. Upon interaction with bacteria or bacteria-derived antigens, neutrophils initiate a multi-staged response of which the terminal stage is NETosis, formation of protease-decorated nuclear DNA into extracellular traps. NETosis has a great propensity to elicit ocular damage and has been associated with diabetic retinopathy and diabetic macular oedema (DME) progression.
