The flexibility of digestive traits characterizes a standard model of physiological flexibility, demonstrating that animals adjust their digestive attributes in order to maximize overall energy return. Using an intraspecific experimental study, we evaluated the amount of flexibility in digestive tract mass and length in individuals from field mouse populations inhabiting semi-arid and temperate...

We present a case report of diffuse polypoid lesions of the digestive tract in which multiple endoscopic techniques (upper endoscopy, colonoscopy, and capsule endoscopy) were performed in order to complete and refine the diagnosis in a patient with severe hypogammaglobulinemia with recurrent infections, bronchiectasies and diffuse nodular lymphoid hyperplasia of the digestive tract. In patients...

We previously described the effects of intake of dairy products on plasmid dissemination in the digestive tract of gnotobiotic mice associated with human faecal flora (HFF) and found that yoghurt, heat-treated yoghurt (HTY) and milk reduced population levels of transconjugants compared with findings in mice fed a standard mouse diet. In the case of lactose intake, transconjugants were not detec...

Hirudo medicinalis, the medicinal leech, usually carries in its digestive tract a pure culture of Aeromonas veronii bv. sobria. Such specificity is unusual for digestive tracts that are normally colonized by a complex microbial consortium. Important questions for the symbiotic interaction and for the medical application after microvascular surgery are whether other bacteria can proliferate or a...

Background and aimsNowadays, probiotic microorganisms are given high attention due to their potential for the improvement of animal production productivity. The natural gut microflora poultry can serve as an excellent source optimum strains. Therefore, this study isolated, identified characterized Lactobacillus strains from digestive tract content RIR chicken in Ethiopia.MethodsA total five chi...

The article considers a method to obtain environmentally friendly aquaculture products (red tilapia (Oreochromis mossambicus × Oreochromis niloticus) by adding the probiotic preparation Ecoflor balanced mixed feed. component of formed several strains bifid and lacto bacteria gives prepa-ration ability improve intestinal microflora fish, activate immune system, remove unfavorable metabolic produ...

In considering the use of digestive enzyme supplements, it is not uncommon to question the survivability of unprotected enzymes through the digestive process. Pancreatic enzymes, available as both drugs and dietary supplements, are known to require enteric coating to prevent permanent denaturing by gastric acidity. Fortunately, not all enzymes require these coatings to survive the gastric envir...

The aerobic intestinal microflora of 2-week-old herring (Clupea harengus) larvae was characterized by using conventional microbiological methods and electron microscopy. Larvae were hatched and kept in filtered seawater or in seawater with penicillin and streptomycin. The gastrointestinal tract of herring larvae is essentially a straight tube divided into two compartments. Light microscopy reve...

Orally ingested probiotic micro-organisms do not exert health effects exclusively in the intestine. Some strains can alleviate or prevent bacterial, fungal or viral infections in other organs by stimulation of the immune system. By preservation or improvement of the barrier function of the intestinal mucosa, they may inhibit translocation of potential pathogens and thus prevent infections of th...
