to clarify fermentative alterations in the large intestine (hindgut) during grazing, fecal alcohol and volatile fatty acids (vfas) concentrations were evaluated in 30 dairy heifers. the heifers were kept in pasture growing mixed grass herbage from spring (mid may) until october, and their rectal feces were collected periodically. concentrations of ethanol, methanol and isopropanol were increase...

CONTEXT Fecal elastase is a noninvasive test for pancreatic insufficiency diagnosis. OBJECTIVES Evaluate the usefulness of fecal elastase 1 for the indication of exocrine pancreatic insufficiency among former alcohol addicts and patients with chronic pancreatitis. METHODS Forty-three patients with chronic pancreatitis and thirty-three asymptomatic former alcohol addicts entered the study. T...

Sample preparation and DNA extraction protocols for DNA amplification by PCR, which can be applied in human fecal samples for taeniasis diagnosis, are described. DNA extracted from fecal specimens with phenol/chloroform/isoamilic alcohol and DNAzol reagent had to be first purified to generate fragments of 170 pb and 600 pb by HDP2-PCR. This purification step was not necessary with the use of QI...

Epidemiological studies have shown an association between consumption of alcoholic beverages, particularly beer, and carcinoma of the large bowel, especially the rectum. We studied the effects of chronic dietary beer and ethanol consumption on experimental colonic carcinogenesis, fecal bile acid and neutral sterol levels, fecal bacterial flora, and colonic epithelial DNA synthesis. Ten-week-old...

Two isolation methods were compared for isolation of Clostridium difficile from food animal feces. The single alcohol shock method (SS) used selective enrichment in cycloserine-cefoxitin fructose broth supplemented with 0.1% sodium taurocholate, followed by alcohol shock and isolation on tryptic soy agar supplemented with 5% sheep blood, and cycloserine-cefoxitin fructose agar. The double alcoh...

Direct inoculation to cefoxitin-cycloserine-fructose agar and broth was compared with alcohol shock-chopped meat broth inoculation for optimal detection of Clostridium difficile in fecal samples. Alcohol shock is significantly more sensitive than cefoxitin-cycloserine-fructose agar or broth and may be the method of choice to detect C. difficile in asymptomatic carriers.

Studies have shown that excessive alcohol consumption impacts the intestinal microbiota composition, causing disruption of homeostasis (dysbiosis). However, this observed change is not indicative of the dysbiotic intestinal microbiota function that could result in the production of injurious and toxic products. Thus, knowledge of the effects of alcohol on the intestinal microbiota function and ...
