چکیده

Naturally occurring dual infections with Escherichia coli of different serogroups occurred in 12 pigs 2 to 14 days of age. In each case, one isolate was hemolytic and produced K88 pili and the other was nonhemolytic and produced either K99 or 987P pili.

Increasing the viscosity of the intestinal contents stimulates proliferation of enterotoxigenic Escherichia coli and Brachyspira pilosicoli in weaner pigs.

The present study was designed to evaluate the effect of increased viscosity of the intestinal digesta on proliferation of enterotoxigenic Escherichia coli and the intestinal spirochaete Brachyspira pilosicoli in weaned pigs. Pigs were fed an experimental diet based on cooked white rice (R), which was supplemented with carboxymethylcellulose (CMC; 40 g/kg diet) to increase digesta viscosity. Th...

Enterotoxigenic Escherichia coli infection induces tight junction proteins expression in mice

Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in travelers, young children and piglets, but the precise pathogenesis of ETEC induced diarrhea is not fully known. Recent investigations have shown that tight junction (TJ) proteins and aquaporin 3 (AQP 3) are contributing factors in bacterial diarrhea. In this study, using immunoblotting and immunohistochemistry analyses, we found that E...

Prevalence of serogroups and genotypes for fimbriae and enterotoxins in <i>Escherichia coli</i> isolated from diarrheic piglets in western China

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...

Efficacy of dietary supplementation of bacteriophages in treatment of concurrent infections with enterotoxigenic <em>Escherichia coli</em> K88 and K99 in postweaning pigs

Postweaning diarrhea or colibacillosis is a costly disease causing substantial mortality, as well as growth retardation, in swine production.1-3 Colibacillosis is typically associated with avid intestinal adhesion and fecal shedding of enterotoxigenic Escherichia coli (ETEC). The ETEC causing diarrhea in postweaning pigs carries the F4 (K88) or F18 fimbrial antigen in most cases.4-6 The F5 (K99...
