A chemical characteristic of the feces of diarrheal piglets permits differentiation among piglets receiving antibiotic treatment and those with colibacillosis or dyspepsia. A high concentration of lactic or succinic acid was observed in the diarrheic feces of piglets receiving antibiotic treatments
We undertook an epidemiologic study for the sensitivity of both Shiga-like toxin (Slt)-producing Escherichia coli (STEC) O157 and non-STEC O157 strains isolated from different patients with diarrhea to hydrochloric acid (HCl) and organic acids such as acetate, propionate, butyrate and lactate, and
We observed a significant difference in the organic acid profile of diarrheal feces between pigs infected with and free from pathogenic spirochetes. Diarrhea and loose feces were collected from growing pigs, held at 15 different commercial farms. A total of 106 samples were measured for organic acid
Gastrointestinal toxicity and various infections are serious problems associated with high-dose chemotherapy. Antibacterial chemoprophylaxis reduces the incidence of gram-negative bacterial infection; however, it may affect the normal intestinal flora and induce drug resistance in organisms. We
Succinate was the major organic acid detected in the hindgut content of pigs suffering from antibiotic-associated diarrhea. Antibiotic-associated diarrhea was induced by an oral dose of polymyxin B sulfate (3,000,000 units/day) or an intramuscular injection of enrofloxacin (0.6 g enrofloxacin/day).
Our objective was to document how intake of Lactobacillus plantarum 299v affects the concentrations of fecal organic acids during and after metronidazole treatment in 19 patients with recurrent Clostridium difficile-associated diarrhea. Fecal samples were analyzed by gas-liquid chromatography. After
The study critically evaluates the changes in the chemical composition of the luminal fluid along the whole length of the small intestine in four children with acute cholera and in one with acute noncholeraic diarrhea. In the children with cholera the total CO2 content rose abruptly from a mean of
The major purpose of this research was to gain insight into the effect of carbohydrate malabsorption on fecal water output. To do this we measured daily fecal output of total carbohydrate, reducing sugars, and organic acids (a product of bacterial fermentation). Normal subjects were studied in their
BACKGROUND
Gut microbiota are known to be closely related to irritable bowel syndrome (IBS). However, not much is known about characteristic fecal metabolic profiles of IBS. We aimed to characterize fecal metabolites in patients with IBS with predominant
diarrhea (IBS-D) using
Two studies were conducted to evaluate the effects of organic acid (OA) supplementation in a highly digestible (Exp. 1) or a less digestible diet (Exp. 2) on the growth performance and intestinal health of weaned pigs. In Exp. 1, a total of 240 pigs weaned at day 21 were assigned to one of five
Whether carbohydrate malabsorption causes diarrhea probably depends on the balance between the osmotic force of the carbohydrate and the compensatory capacity of the colon to dispose of the carbohydrate by bacterial fermentation. The present study evaluated the specific role of the osmolarity by
Organic short and medium chain fatty acids are used in diets for piglets because they have an impact on the digestive processes and the intestinal microbiota. In this study, 48 pens (2 piglets/pen) were assigned randomly to 4 diets, without additive (control), with organic acids (OA; 0.416% fumaric
Gut health of nursery pigs immediately after weaning is tightly associated with their growth performance and economic values. Postweaning diarrhea (PWD) is one of the major concerns related to gut health of nursery pigs which often is caused by infections of enterotoxigenic Escherichia coli (ETEC),
Fecal metabolites are associated with gut visceral sensitivity, mucosal immune function and intestinal barrier function, all of which have critical roles in the pathogenesis of irritable bowel syndrome (IBS). However, the metabolic profile and pathophysiology of IBS are still unclear. Three experiments were conducted to assess the response of weaned pigs to organic acid SF3, which contains 34% calcium formate, 16% calcium lactate, 7% citric acid and 13% medium chain fatty acids. Dietary treatments had no effect on growth performance of piglets (21-day weaning) fed the commercial
