BACKGROUND Probiotic supplementation significantly reduces the risk of necrotising enterocolitis (NEC) and all cause mortality in preterm neonates. Independent quality assessment is important before introducing routine probiotic supplementation in this cohort. AIM To assess product quality, and confirm that Bifidobacterium breve (B. breve) M-16V(More)
Consumption of Lactobacillus spp. has been shown to enhance immune responses in mice. This study examined the immuno-adjuvant capacity of two strains: Lactobacillus acidophilus L10 and Lactobacillus fermentum PC2, in the induction of protective humoral immunity in a Salmonella Typhimurium vaccine challenge model. Briefly, BALB/c mice were divided into four(More)
BACKGROUND Gut development, function and colonisation are impaired in animal models of prematurity with intrauterine growth restriction (IUGR). The effect of Bifidobacterium breve (B. breve) supplementation on faecal bifidobacteria in small for gestational age (SGA: birth weight <10th centile due to IUGR) preterm infants is not known. OBJECTIVE We(More)
This study examined the influences of the dosage of the adjuvant, the nature of the antigen and the host genetics on the capacity of L. fermentum PC1 (PC1) to function as an oral adjuvant. BALB/c and DBA/1 mice were vaccinated with either ovalbumin (OVA) or Salmonella Typhimurium on days 0 and 14, Mice were also dosed with the PC1 (10⁸ CFU or 10(11) CFU per(More)
Community-level selection is an important concept in evolutionary biology and has been predicted to arise in systems that are spatially structured. Here we develop an experimental model for spatially-structured bacterial communities based on coaggregating strains and test their relative fitness under a defined selection pressure. As selection we apply(More)
