Résumé La maladie cœliaque est un trouble auto-immun associé à une intolérance au Gluten qui a pour effet la destruction progressive des villosités de l’intestin grêle. Les symptômes de la maladie cœliaque sont très divers et peuvent se produire à tout âge. Parmi ces symptômes, la maladie abortive est une circonstance rare de découverte de la maladie cœliaque. Nous rapportons le cas d’une patie...

Of 1,004 isolates of Escherichia coli obtained during the spring of 1975 in seven different states from calves with diarrhea, 124 isolates were enterotoxigenic based upon ability to cause distention of the calf ligated intestinal segment. Isolates of enterotoxigenic E. coli (ETEC) were obtained from calves in six of the seven states. ETEC were detected in calves in 118 of 355 herds in Montana d...

Porcine neonatal diarrhea and postweaning diarrhea caused by enterotoxigenic Escherichia coli (ETEC) result in significant morbidity and mortality and are economically important diseases of pigs.1 Secretory diarrhea associated with ETEC infection is mediated by any of several enterotoxins, including heat labile enterotoxin (LT), heat-stable enterotoxin-a (STa), and heat-stable enterotoxin-b (ST...

Polymerase chain reaction for five fimbriae (K88, K99, 987P, F41, F18), two heatstable enterotoxins (STa, STb), one heatlabile enterotoxin (LT), and Shiga-like toxin type II (SLT) was performed on Escherichia coli isolates to determine their genotype among isolates from weaned pigs with diarrhea and/or edema disease in North Carolina. A total of 175 isolates were tested. All but two isolates po...

In this study it was shown that the O101 lipopolysaccharide isolated from Escherichia coli B41 did not contain an O-specific polysaccharide and that its sugar moiety is probably restricted to the core oligosaccharide. It is characterized by the presence of galactose, glucose, N-acetylglucosamine, heptose and 3-deoxy-D-manno-2-octulosonic acid and the fatty acid composition is typical of an Ente...

Some interrelationships among age, ambient temperature, intestinal transit, and enterotoxigenic Escherichia coli infection were studied in an infant mouse model. The transit of dye in the small intestine was accelerated during the response to heat-stable E. coli enterotoxin. Transit in the small intestine of normal mice accelerated with increased age (from less than 17 h to 8 days old) and acce...

The prevalence of diarrhoea in calves was investigated in 8 dairy farms in Mozambique at 4 occasions during 2 consecutive years. A total of 1241 calves up to 6 months of age were reared in the farms, and 63 (5%) of them had signs of diarrhoea. Two farms had an overall higher prevalence (13% and 21%) of diarrhoea. Faecal samples were collected from all diarrhoeal calves (n = 63) and from 330 hea...
