Background. The purpose of this study is to assess the effect of clindamycin (150 mg qid for 10 days) and ciprofloxacin (500 mg bd for 10 days) on the skin, nasal, saliva and intestinal microflora of healthy humans for a period of one year In addition, the consequences of the emergence and persistence of clindamycin and ciprofloxacin resistant bacteria in the normal microflora were studied. Met...

1. Amylase (EC 3.2.1.1) activity found in the intestinal tract of chicks posterior to the stomach is of endogenous origin, as amylase in the food is inactivated by the low pH in the stomachs. 2. Ingestion of raw soya-bean diet (RSD) or of heated soya-bean diet (HSD) supplemented with trypsin inhibitors induced higher amylase activites in the lower part of the small intestine and caecum as compa...

451 Abstract: An experiment was conducted to determine the effects of an organic acid combination (Acid Lac Dry: lactic, fumaric, propionic, citric and formic acid) and/or zinc bacitracin on the body weight gain, feed efficiency, microflora and pH in the ileum content of broiler-type chicks. Ross PM3 broiler chicks were placed in an experimental design that consisted of four dietary treatments ...

Onion (Allium cepa) bulb from Liliaceae has antioxidant, spasmolytic and antihypertensive activities. The aim of present study was to investigate the antispasmodic effect of onion peel on rat ileum contractility. Onion peel powder was extracted by maceration in 70% alcohol for 72 h. A terminal portion of ileum from male Wistar rat was dissected and its contractions were recorded isotonically in...

To evaluate the effects of hyperglycemia and insulin treatment on proportion serotonin-immunoreactive (5-HT-IR) myenteric neurons, samples were taken from duodenum, ileum, colon diabetic, insulin-treated control rats 10 weeks after onset streptozotocin-induced hyperglycemia. Myenteric whole-mount preparations immunostained with anti-5-HT pan-neuronal anti-HuCD markers. In controls, 5-HT-IR neur...

The effect of dietary fat source (soy oil or a mixture of lard and tallow) and dietary supplementation with antibiotics (a combination of avilamycin at 10 mg kg of feed(-1) and salinomycin at 40 mg kg of feed(-1)) on the bacterial community in the ileum of broiler chickens at different ages (7, 14, 21, and 35 days) was studied using PCR with denaturing gradient gel electrophoresis (DGGE) analys...

Background: It is possible to manipulate the composition of the gastrointestinal microflora by administration of preand probiotics. This may help to preserve gut barrier function and reduce the incidence of septic morbidity. Aims: To assess the effects of a combination of preand probiotics (synbiotic) on bacterial translocation, gastric colonisation, systemic inflammation, and septic morbidity ...

Many studies dealing with trinitrobenzene sulfonic acid (TNBS) colitis in rats have been carried out referring only to the colon. In humans, ulcerative colitis (UC) can extend a variable distance into the terminal ileum in a phenomenon known as backwash ileitis (BWI). The aim of this study was therefore to examine the effect of TNBS-induced colitis on different aspects of the rat ileum and jeju...

The effect of cereal non-starch polysaccharides (NSP) on the gut microbial populations was studied in 5 growing pigs between 39-116 kg body weight according to a Latin square design. The diets were composed to contain different NSP levels. The control diet had a normal NSP content (139 g/kg dry matter (DM)), 2 diets had a low total amount of NSP (95 and 107 g/kg DM) and 2 diets had a high amoun...

Lactic acid bacteria are probiotics widely used in functional food products, with a variety of beneficial effects reported. Recently, intense research has been carried out to provide insight into the mechanism of the action of probiotic bacteria. We have used gene array technology to map the pattern of changes in the global gene expression profile of the host caused by Lactobacillus administrat...
