A 145-acre potato field adjacent to Dorris, California, was treated with ethoprop (Mocap) to control nematodes. Ethoprop releases n-propyl mercaptan, a highly odorous and volatile gas, as a degradation product of the pesticide. An epidemiological investigation was undertaken by the California
A randomized clinical trial was completed to study the severity, duration, and nutritional outcome of acute diarrhea in 85 Peruvian children between 5 and 24 months of age who received a soy-protein-isolate, lactose-free formula (group SF) or one of two mixtures of home-available foods, all in
BACKGROUND
Olestra, a nonabsorbable, energy-free fat substitute used in snack foods, has been anecdotally reported to cause gastrointestinal (GI) adverse events, although such effects were not expected based on results from randomized trials, in which it was consumed in typical snack
The aim of this study was to determine the effects of olestra and sorbitol consumption on three accepted objective measures of diarrhea (stool output >250 g/day, liquid/watery stools, bowel movement frequency >3/day), and how stool composition influences reports of common gastrointestinal symptoms.
Postweaning diarrhea (PWD) in pigs is a leading cause of economic loss in pork production worldwide. The current practice of using antibiotics and zinc to treat PWD is unsustainable due to the potential of antibiotic resistance and ecological disturbance, and novel methods are required. In this
BACKGROUND
Potato allergy has been described rarely, generally in relation to the Oral Allergy Syndrome (OAS). Adults with seasonal allergic rhinitis have been reported in whom peeling of raw potatoes causes oculonasal symptoms, wheezing, and contact urticaria. Skin testing with fresh fruits and
We evaluated the effect of raw potato starch (RPS) on growth performance, postweaning diarrhea, and gastrointestinal microbial populations in weaned piglets. Eighty-four piglets were weaned at 17 +/- 2 d of age with an average BW of 6.0 +/- 0.9 kg. Pigs were blocked by BW and assigned to 1 of 4
A method for measuring the transit time of a meal, containing sausages, mashed potato, baked beans, and a pineapple custard dessert, through the gastrointestinal tract was evaluated in 14 healthy volunteers. Gastric emptying was determined by incorporating a radioactive marker in the meal and
BACKGROUND
Folk herbal medicine knowledge and its utilization by aboriginal cultures are not only useful for conservation of cultural traditions and biodiversity, but also useful for community healthcare and drug discovery in the present and in the future.
OBJECTIVE
Using a semi-structured
Colonic bacterial production of short-chain fatty acids (SCFA) plays an important role in the salvage of unabsorbed carbohydrate and in colonic absorption of electrolytes and water. The objective of this study was to determine whether patients with diarrhea-predominant irritable bowel syndrome
BACKGROUND
In June 1998, we investigated one of the largest foodborne outbreaks of enterotoxigenic Escherichia coli gastroenteritis reported in the United States.
METHODS
We conducted cohort studies of 11 catered events to determine risk factors for illness. We used stool cultures, polymerase chain
The occupational health nurse in a large manufacturing facility arrives at work early one Monday morning to find three ill employees in the clinic waiting room and a message from several plant supervisors that multiple employees have called in sick. The supervisors are concerned. The employees have
Weaned piglets commonly suffer from gastroenteritis caused by enterotoxigenic Escherichia coli K88. Our aim was to produce E. coli strains that inhibited the growth of E. coli K88 and could be used as a probiotic against postweaning diarrhea. The inclusion criteria for the probiotics were that in
Corn, feed, and litter samples reported to be associated with feed refusal, diarrhea, leg weakness, and mortality were evaluated for the presence of toxic substances. Intubated residues of ethyl acetate extracts of these samples did not cause gross lesions, diarrhea, or mortality in young New
BACKGROUND
Cyclospora cayetanensis is a recently recognized parasite that causes prolonged diarrheal illness. Its modes of transmission have not been fully determined, although some investigations before 1996 implicated water. Outbreaks of cyclosporiasis in the United States in 1996 and 1997 are
