diet components are one of the determination factors for changing of morphology of small intestines which lead to a change in digestien and absorption of nutritiond subs tonces.to study the histomorphometric changes of small intestine due to hull- less barley food diets in poultry, 20, of 70 weeks old healthy road island red cocks were selected and divided equally into 2 experimental groups and...

Bile salts is one of essential components bile secreted into the intestine to confer antibacterial protection. Cronobacter species are associated with necrotizing enterocolitis in newborns and show a strong tolerance salts. However, little attempt has been made focus on molecular basis In this study, we investigated roles tolC growth, cell morphology, motility, biofilm formation ability malonat...

An experiment was conducted on broiler chickens to study the effects of conjugated linoleic acid (CLA), fish oil, both at 7% of the diet, or their mixtures at 3.5% of the diet, on the performance, carcass traits and intestinal morphology of broiler chickens. The chicks fed with 7% fish oil or 7% CLA diets, were found to have an inferior weight gain in grower and finisher phases, respectively. A...

Background: There are some reports on the positive effectsof dietary insoluble fiber on the performance of broilers. Objectives: This study was carried out to determine theeffect of inclusion rate and particle size of rice husk in the diet of broilerson the ileal and cecal bacteria populations and small intestine morphology. Methods: The experimental diets  consisted of a control husk-free diet...

The study on how the digestive system responds to environmental stimuli and malnourishment is nowadays considered a hot topic of research. Unfortunately the effects of different diets on the intestine morphology and also on its associated systems, such as endocrine and nervous systems, are almost unknown, despite some studies indicate that the microbial composition of mucosal communities in hum...

Mammalian vasculature, and the analogous tracheal system in Drosophila, can respond dynamically to hypoxic conditions to maintain a constant supply of oxygen to peripheral tissues. In a recent study published in Cell, Linneweber et al (2014) reveal that tracheal plasticity can also be regulated by nutrient availability, through both systemic and local insulin signaling. They also show that spec...

Neosporosis was diagnosed in a 16-year-old female white rhinoceros (Ceratotherium simum) that died suddenly without clinical signs. Histopathology revealed disseminated protozoan tachyzoites in liver, adrenal cortex, kidney, and intestine, with morphology compatible with either Toxoplasma or Neospora. The organism was identified as Neospora caninum with the use of primary rabbit anti-N. caninum...

Background. Gut microbiota plays an important role in the human body, antimicrobial drugs intake being one of main factors affecting composition. Antibiotics suppress normal intestinal microflora allowing for growth and development pathogenic flora. Objective. To study effect meropenem imicenem on microbiocenosis morphology small intestine rats. Material methods. In experiment rats, we analysed...

Intestinal changes, mainly in the jejunum, were investigated in 13 cases of malignant histiocytosis at necropsy and who had presented as lethal midline granuloma. Villous atrophy with crypt hyperplasia was observed in all cases, and a proliferation of atypical histiocytes was observed in seven cases. In the remaining cases, histiocytes with normal morphology increased in number. These findings ...

In a parasitological survey of free-ranging Cerdocyon thous (Carnivora: Canidae) from Brazilian Caatinga shrubland, a new species of Pterygodermatites (Multipectines) was recovered from the small intestine of this host. Morphological analysis showed that P. (Multipectines) pluripectinata n. sp. is distinguished from all other congeneric species mainly by the numerous plate-like projections and ...
