High Doses of Halotolerant Gut-Indigenous Reduce Cultivable Lactobacilli in Newborn Calves without Increasing Its Species Abundance.

To elucidate the ecological effect of high oral doses of halotolerant (resistant to table salt) indigenous-gut bacteria on other commensals early in life, we conducted a culture-based study to quantify the effect of intestinal strain of bovine origin (with remarkable aerobic growth capabilities and inhibitory activity against O157:H7 and F5) on clinical health and gut lactobacilli/coliforms in newborn calves. In a double-blind placebo-randomized trial twelve colostrum-fed calves, consecutively born at a farm, were fed within 12 hours from birth at low (10 CFU/day) or high concentrations (10) or placebo (q24 h, 5 d; 10 d follow-up). We developed a 2.

Comparison of the fecal bacterial microbiota of healthy and diarrheic foals at two and four weeks of life.

Background: Diarrhea in foals affects up to 60% of foals during the first six months of life. The effect of diarrhea on the fecal bacterial microbiota in foals has not been investigated. Little is known on the fecal bacterial microbial richness and diversity of foals at a young age.

Prevalence of netF-positive Clostridium perfringens in foals in southwestern Ontario.

NetF-producing Clostridium perfringens have recently been identified as a cause of necrotizing enteritis in neonatal foals, but little is known about its prevalence in clinically normal foals. Foals (n = 88) ranging in age from < 1 wk to 2 to 4 mo (median age 2 to 4 wk) on 8 horse-breeding farms in Ontario were examined on 1 or 2 occasions for the presence of C. perfringens.

The longitudinal effect of a multi-strain probiotic on the intestinal bacterial microbiota of neonatal foals.

Reasons For Performing The Study: The microbiota plays a key role in health and disease. Probiotics are a potential way to therapeutically modify the intestinal microbiota and prevent disease.

Objectives: The aim of this study was to investigate the effects of probiotics on the bacterial microbiota of foals during and after administration.

Effects of transport, fasting and anaesthesia on the faecal microbiota of healthy adult horses.

Reasons For Performing Study: The intestinal microbiota is important for health and disease. Factors that disturb the equine intestinal microbiota need further investigation.

Objectives: To determine the effects of transport, fasting and anaesthesia on the faecal microbiota of healthy adult horses using next-generation sequencing.
