Abstract:

Le déoxynivalénol (DON) est une mycotoxine de type trichothécène de type B, principalement produite par le genre Fusarium. C'est l'une des mycotoxines les plus répandues, elle est largement trouvée dans les céréales et les produits dérivés des céréales. Le cadmium est un composant de la croûte terrestre et un polluant environnemental courant. C'est un métal trace non essentiel et toxique pour la santé des humains et des animaux. Bien que la toxicité individuelle du DON et du Cd ait été bien étudiée, leur effet combiné est peu étudié. L'intestin étant le premier organe ciblé par les contaminant

Abstract:

Enterohaemorrhagic E. coli (EHEC) are important gastrointestinal pathogens of humans. E. coli serotype O157:H7 is the EHEC most commonly associated with human illness. E. coli O157:H7 is carried asymptomatically by cattle which form an important reservoir for the bacterium. E. coli O157:H7 has been found to colonise at the terminal rectum of cattle in preference to other sites in the bovine gastrointestinal tract. The first objective of this work was to characterise the roles of bacterial secreted components responsible for key functions in the modulation of host defences against EHEC. Data pr

Il est important de souligner que malgré les thérapies actuelles, les personnes diabétiques de type 1 présentent encore une qualité de vie considérablement altérée et une espérance de vie réduite.

Abstract:

The small intestine is prone to infections by bacteria that can adhere to the surface wall. We wish to better understand an infection of the small intestine caused by enteropathogenic Escherichia coli (EPEC) and to achieve this objective we present three models: a chemostat and two mechanistic spatial models in 1-D and 2-D. The chemostat model is a dynamic model where four biologically significant steady states of the infection were observed: washout, persistence, threshold, and blowup. These results concur with previous work done in this field; however in this instance our model is far less c

Abalone are marine molluscs that are highly prized seafood delicacies. Australia produces more than 1,000 metric tonnes of abalone from aquaculture. Abalone aquaculture research priorities are to improve the growth rates and reduce the mortalities of abalone in aquaculture. Currently, little is known about the microbial communities associated with Australian abalone aquaculture; however, pathogens are associated with high mortality rates in the summer months.

Abstract:

Introduction: Intestinal bacteria influence gut morphology by affecting epithelial cell proliferation, development of the lamina propria, villus length and crypt depth [1]. Gut microbiota-derived factors have been proposed to also play a role in the development of a 30 % longer intestine, that is characteristic of PRM/Alf mice compared to other mouse strains [2, 3]. Polyamines and SCFAs produced by gut bacteria are important growth factors, which possibly influence mucosal morphology, in particular villus length and crypt depth and play a role in gut lengthening in the PRM/Alf mouse.

Abstract:

Long term consumption of a high fat diet (HFD) increases the risk of developing Metabolic Syndrome and type 2 diabetes. This led us to hypothesize that long term HFD consumption impairs immune tolerance to the intestinal bacteria. Our studies had two goals. First, we characterized the effect of long term HFD consumption on the systemic immune response by comparing C57BL6 mice fed a HFD and low fat diet (LFD). Plasma immunoglobulin G (IgG) against Escherichia coli (LF-82), E. coli (Nissle 1917), Bacteroides thetaiotaomicron and Lactobacillus acidophilus were measured by a lab-developed ELISA. F

Previous studies examining the canine intestinal microflora have focused on cultivation of bacteria from intestinal content. Recently, it has been recognized that the majority of bacteria cannot be identified using standard culture techniques. The aim of this study was to describe the composition and dynamics of the canine intestinal microflora using molecular methods based on identification of the 16S ribosomal DNA (16S rDNA) and to evaluate the clinical use of a 13C-glycocholic acid blood test (13CGCBT) as a serum marker for small intestinal bacterial biomass.

Abstract:

The gross intestinal configuration of the Nile tilapia intestine changed dramatically from a short, straight intestinal tube at hatch (day 0) to a very complex, coiling pattern first attained at 9 weeks post-hatch. During the developmental period, gut length increased from 90% to 410% of body length. The rate of increase in both intestinal and body lengths took place at an accelerating rate as the fish aged. The great intestinal length provides an advantage to the fish in digestion and absorption of nutrients present in the less energy-efficient herbivorous diet. Formulation of commercial diet

The aims were to characterise the expression of melatonin and its receptors MT1 and MT2 in normal human gastrointestinal tract and pancreas as well as in tumours derived from enterochromaffin cells, small intestinal neuroendocrine tumours (SI-NET),

In the UK, studies of ExPEC have focused on isolates from the North of England, ST131 strains and ExPEC that possess extended-spectrum beta-lactamase (ESBL) enzymes.

Abstract:

The small intestinal permeability barrier is dependent on tight junction (TJ) complexes that separate the external lumen from the underlying mucosa. Apical TJs consist of integral transmembrane proteins including occludin, claudins and ZO-1 as well as the cytoplasmic plaque of TJ-associated adaptor, scaffolding and signalling proteins. Although the function of occludin at the TJ remains unclear, the dynamic mobility of occludin, claudins and ZO-1 to and from the TJ suggests occludin may play a key role in regulation of TJ structure and function, regulated by occludin phosphorylation status.

Abstract:

Die Tyrosin Kinase Brk stellt den Prototypen nicht N-terminal myristoylierter, Nicht-Rezeptor Tyrosin Kinasen dar. Die Expression dieser Kinase ist auf epitheliale Gewebe beschränkt und wird während der Entwicklung differentiell reguliert. In normalen Geweben ist die Brk Expression auf nichtproliferierende, terminal differenzierte Zellen beschränkt. Um die regulatorische Funktion von Brk im murinen Darmepithel zu untersuchen, wurde das brk Gen in der Maus inaktiviert. Brk knockout Mäuse zeigten keine offensichtlichen Defekte in ihrer Entwicklung jedoch eine erweiterte Proliferationszone in den

Abstract:

Background Necrotising enterocolitis (NEe) remains a leading cause of mortality in neonatal intensive care units. There is currently a poor understanding of the molecular mechanisms underlying the pathogenesis of NEC and a lack of effective treatment strategies. Studies performed by various groups suggest that intestinal barrier failure plays a critical role in the development of NEC. The intestinal mucosal barrier is a complex defence system against the onslaught of noxious substances within the lumen, while allowing the influx of nutrients.

Abstract:

Rat exon microarrays were utilized to detect changes in mRNA expression and alternative splicing in the liver, duodenum, jejunum, and ileum of the lactating rat when compared to age-matched virgin controls. Analysis of data at the level of gene expression revealed differential expression of genes involved in cholesterol biosynthesis in each tissue examined, suggesting increased Sterol Response Element Binding Protein activity. We also detected decreased mRNA from components of the T-cell signaling pathway in the jejunum and ileum. We characterized expression of solute carrier and adenosine tri

Abstract:

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>Seawater teleost fish are hyposmotic to their environment and as a consequence must deal with a constant diffusive loss of water and a net gain of salts. In contrast to living in seawater, teleosts fish in a freshwater environment are faced with the opposite dilemma, a constant osmotic influx of water and depletion of salts. Between these environments there are estuarine regions, which are habitats of several species. The purpose of this study was to investigate Na+, Cl-, K+, Ca2+, and Mg2+ levels in the fluid phase and total amoun

Abstract:

Bacillus cereus is one of the known causes of diarrhoeal food poisoning. In their natural environment of soil surviving as spores facilitates their colonisation of raw food ingredients enabling their access to the food chain. Recently psychrotrophic strains of B. cereus have been reclassified based on divergent cold shock gene (cspA) sequences and renamed B. weihenstephanensis. It is the modified cspA gene that is thought to confer the psychrotolerant phenotype witnessed by these strains. Aside from cspA, B. cereus and B. weihenstephanensis are closely related, leading to questions about its p
