The effects of voluntary wheel-running exercise on cecal microbiota and short-chain fatty acid production were investigated in rats. The microbiota composition was notably different between the exercised and sedentary rats. Furthermore, the exercised rats showed a significantly higher n-butyrate concentration than the sedentary rats. This alteration of the(More)
Porcine edema disease (ED) is caused by Shiga toxin 2e-producing Escherichia coli (STEC). ED has become frequent in pig farms, and the use of antimicrobials has resulted in the development of antimicrobial-resistant STEC. Accordingly, the use of materials other than antimicrobials is requested for the prevention of ED. Oral administration of a heat-killed(More)
Weakly tumorigenic and nonmetastatic QR-32 cells derived from a fibrosarcoma in C57BL6 mouse are converted to malignant cells once they have grown after being coimplanted with a gelatine sponge which induces inflammation. We administered a newly developed peroral superoxide dismutase (SOD), oxykine, and as control vehicle, gliadin and saline, starting 2(More)
Edema disease (ED) has become frequent in Japan, but no effective method for experimental infection has been developed. We report here the use of a capsule that resistant against gastric digestion to induce the ED in piglets. Four 21-day-old piglets were used. Shiga toxin 2e-producing Escherichia coli (STEC) cell pellet was encapsulated and administered(More)
The use of antimicrobials in broilers is considered to be a cause of the appearance of vancomycin-resistant enterococci (VRE). Once VRE penetration occurs, whatever its origin, it is difficult to expel the enterococci from the intestine because of their multiple resistance, whether natural or acquired. In this study, we evaluated the prevention of VRE(More)
The immune system in juvenile calves is immature, so calves are susceptible to several diarrheal and respiratory diseases. Oral administration of lactic acid bacteria (LAB) is known to improve the growth performance and prevent diarrheal and respiratory diseases by stimulating the immune system in juvenile calves. Most of the immunostimulation by LAB is(More)
The effect of a heat-killed cell preparation of Enterococcus faecalis strain EC-12 (EC-12) on the gene expression of Na(+)-K(+)-2Cl(-) co-transporter 1 (NKCC1) in intestinal epithelial cells was evaluated by using rats. The NKCC1 gene in ileal epithelial cells was significantly up-regulated by the oral administration of EC-12. The results of this study(More)
Early weaning induces villous atrophy in the small intestine (SI) of piglets. Oral administration of live lactic acid bacteria (LAB) can improve villous shortening. In this study, we evaluated the oral administration of a heat-killed and dried cell preparation of Enterococcus faecalis (a LAB) strain EC-12 against villous atrophy in early-weaned mice(More)
