“Blown-pack” spoilage of beef by psychrotrophic Clostridium spp. occurs sporadically and resistance of the endospores to most interventions makes them very difficult to control. Current interventions used to control spoilage and pathogenic bacteria, such as acid washes and heat treatments, do...

Host resistance to bacterial infections is thought to be dictated by host genetic factors. Infections by the natural murine enteric pathogen Citrobacter rodentium (used as a model of human enteropathogenic and enterohaemorrhagic E. coli infections) vary between mice strains, from mild...

Background Campylobacter jejuni causes enterocolitis in humans, but does not incite disease in asymptomatic carrier animals. To survive in the intestine, C. jejuni must successfully compete with the microbiota and overcome the host immune defense. Campylobacter jejuni colonization success varies...

Multiple sclerosis (MS) is a common cause of non-traumatic neurologic disability with high incidence in many developed countries. Although the etiology of the disease remains elusive, it is thought to entail genetic and environmental causes, and microbial pathogens have also been envisioned as...

Background: The Human Microbiome is an area of increasing interest, both in and outside of the scientific community. While overall knowledge has increased exponentially, many aspects remain unclear, such as mechanisms of host-interaction and persistence. Intracellular bacteria have previously...

Non-digestible oligosaccharides (NDO) were shown to reduce inflammation in experimental colitis, but it remains unclear whether microbiota changes mediate their colitis-modulating effects. This study assessed intestinal microbiota and intestinal inflammation after feeding chemically defined...

The nature of weaning, considered the most stressful and significant transition experienced by dairy calves, influences the ability of a calf to adapt to the dramatic dietary shift, and thus, can influence the severity of production losses through the weaning transition. However, the effects of...

Background Diet and environment impact the composition of mammalian intestinal microbiota; dietary or health disturbances trigger alterations in intestinal microbiota composition and render the host susceptible to enteric pathogens. To date no long term monitoring data exist on the fecal...

Introduction: Antimicrobial exposure in early life has been associated with gut microbiota dysbiosis and development of allergic diseases in childhood. In adults and older children, C. difficile is the major pathogen responsible for antibiotic-induced diarrhea but the effect of colonization with...

The effects of high pressure, temperature, and antimicrobial compounds on endospores of Clostridium spp. were examined. Minimal inhibitory concentrations (MIC) of nisin and reutericyclin were determined for vegetative cells and endospores of Clostridium sporogenes ATCC 7955, Clostridium...
