Human milk oligosaccharides (HMO) are major components of breast milk that may have local effects in the gastrointestinal tract and systemic functions after being absorbed, both depending on their metabolism. Using preterm pigs, we investigated the metabolic fate of HMO in three experiments with two different HMO blends. In addition, we examined ef...

Background: Vultures have adapted the remarkable ability to feed on carcasses that may contain microorganisms that would be pathogenic to most other animals. The holobiont concept suggests that the genetic basis of such adaptation may not only lie within their genomes, but additionally in their associated microbes. To explore this, we generated sho...
Article
Aquaculture will play an essential role in feeding a growing human population, but several biological challenges impede sustainable growth of production. Emerging evidence across all areas of life has revealed the importance of the intimate biological interactions between animals and their associated gut microbiota. Based on challenges in aquacultu...

The exciting promises of functional metagenomics for the efficient discovery of novel biomolecules from nature are often hindered by factors associated with expression hosts. Aiming to shift functional metagenomics to a host independent innovative system, we here report on the cloning, heterologous expression and reconstitution of an RNA polymerase...

Background SP-D is an important host defense lectin in innate immunity and SP-D deficient mice show several abnormal immune effects and are susceptible to allergen-induced airway disease. At the same time, host microbiome interactions play an important role in the development of allergic airway disease, and alterations to gut microbiota have been l...

Background The airways of healthy humans harbor a distinct microbial community. Perturbations in the microbial community have been associated with disease, yet little is known about the formation and development of a healthy airway microbiota in early life. Our goal was to understand the establishment of the airway microbiota within the first 3 mon...
Article
Human milk oligosaccharides (HMOs) may mediate prebiotic and anti-inflammatory effects in newborns. This is particularly important for preterm infants who are highly susceptible to intestinal dysfunction and necrotizing enterocolitis (NEC). We hypothesized that HMO supplementation of infant formula (IF) improves intestinal function, bacterial colon...
Article

Background Vitamin D is under scrutiny as a potential regulator of the development of respiratory diseases characterised by chronic lung inflammation, including asthma and chronic obstructive pulmonary disease. It has anti-inflammatory effects; however, knowledge around the relationship between dietary vitamin D, inflammation and the microbiome in...
Article
Mother's own milk is the optimal first diet for preterm infants, but donor human milk (DM) or infant formula (IF) are used when supply is limited. We hypothesized that a gradual introduction of bovine colostrum (BC) or DM improves gut maturation, relative to IF during the first 11 days after preterm birth. Preterm pigs were fed gradually advancing...

Vultures are scavengers that fill a key ecosystem niche, in which they have evolved a remarkable tolerance to bacterial toxins in decaying meat. Here we report the first deep metagenomic analysis of the vulture microbiome. Through face and gut comparisons of 50 vultures representing two species, we demonstrate a remarkably conserved low diversity o...
Article
Methane (CH4) emission was investigated in artificially reared growing lambs fed milk replacer and cream. This study was part of a larger study with 70 lambs, of which 18 lambs with an average body weight of 21 ± 3.6 kg (mean ± SD) were used. The lambs were housed in individual pens (1.5 × 1.5 m). From 3 until 180 days of age, they were fed either...

Recent studies have shown that wild ruminants are sources of previously un-described microorganisms, knowledge of which can improve our understanding of the complex microbial interactions in the foregut. Here we investigated the microbial community of 7 wild-caught giraffes (Giraffa camelopardalis), 3 of which were fed natural browse and 4 were fed...

This work provides the first description of the bacterial population of the lung microbiota in mice. The aim of this study was to examine the lung microbiome in mice, the most used animal model for inflammatory lung diseases such as COPD, cystic fibrosis and asthma.Bacterial communities from broncho-alveolar lavage fluids and lung tissue were compa...

Background The aim of this study was to investigate the effect of various classes of clinically relevant antibiotics at sub-lethal concentrations on virulence gene expression and biofilm formation in Staphylococcus aureus. Findings LacZ promoter fusions of genes related to staphylococcal virulence were used to monitor the effects of antibiotics on...
