Bifidobacterial Succession and Correlation Networks in a Large Unselected Cohort of Mothers and Their Children
Avershina, Ekaterina; Storrø, Ola; Øien, Torbjørn; Johnsen, Roar; Wilson, Robert; Egeland, Thore; Rudi, Knut (Journal article; Peer reviewed, 2013)Bifidobacteria are a major microbial component of infant gut microbiota, which is believed to promote health benefits for the host and stimulate maturation of the immune system. Despite their perceived importance, very ... -
Correlations between Lumbricus terrestris survival and gut microbiota
Rudi, Knut; Strætkvern, Knut Olav (Journal article, 2012)Background: The interplay between diet, gut bacteria and health still remain enigmatic. Here, we addressed this issue through the investigation of the effect of crystalline cellulose on the earthworm Lumbricus terrestris ... -
Culture dependent and independent analyses suggest a low level of sharing of endospore-forming species between mothers and their children
Avershina, Ekaterina; Larsen, Marte Gro; Aspholm, Marina Elisabeth; Lindbäck, Toril; Storrø, Ola; Øien, Torbjørn; Johnsen, Roar; Rudi, Knut (Peer reviewed; Journal article, 2020)Spore forming bacteria comprise a large part of the human gut microbiota. However, study of the endospores in gut microbiota is limited due to difficulties of culturing and numerous unknown germination factors. In this ... -
Exploring the brine microbiota of a traditional Norwegian fermented fish product (Rakfisk) from six different producers during two consecutive seasonal productions
Bjerke, Guro alette; Rudi, Knut; Avershina, Ekaterina; Moen, Birgitte; Blom, Hans; Axelsson, Lars Torsten (Peer reviewed; Journal article, 2019)The purpose of this study was to explore the microbiota of Norwegian fermented fish (rakfisk), a traditional product popular in the Norwegian market. Brine samples, collected from six producers during two subsequent years, ... -
Faecal short-chain fatty acids - a diagnostic biomarker for irritable bowel syndrome?
Farup, Per Grønaas; Rudi, Knut; Hestad, Knut (Journal article; Peer reviewed, 2016)Background The diagnosis of irritable bowel syndrome (IBS) relies on symptom-based criteria. A valid and reliable biomarker that could confirm the diagnosis is desirable. This study evaluated the properties of faecal ... -
Functional Bowel Disorders Are Associated with a Central Immune Activation
Farup, Per Grønaas; Ueland, Thor; Rudi, Knut; Lydersen, Stian; Hestad, Knut (Peer reviewed; Journal article, 2017)Background. Subjects with depression and unexplained neurological symptoms have a high prevalence of gastrointestinal comorbidity probably related to the brain-gut communication. This study explored associations between ... -
Gut Microbiota in HIV Infection: Implication for Disease Progression and Management
Nwosu, Felix Chinweije; Avershina, Ekaterina; Wilson, Robert Charles; Rudi, Knut (Journal article; Peer reviewed, 2014)Survival rates among HIV patients have significantly improved since the introduction of antiretroviral therapy (ART) in HIV management. However, persistent disease progression and clinical complications in virally suppressed ... -
HumGut: a comprehensive human gut prokaryotic genomes collection filtered by metagenome data
Hiseni, Pranvera; Rudi, Knut; Wilson, Robert Charles; Hegge, Finn Terje; Snipen, Lars (Peer reviewed; Journal article, 2021)Background A major bottleneck in the use of metagenome sequencing for human gut microbiome studies has been the lack of a comprehensive genome collection to be used as a reference database. Several recent efforts have ... -
Liquid array diagnostics: A novel method for rapid detection of microbial communities in single-tube multiplex reactions
Hiseni, Pranvera; Wilson, Robert Charles; Storrø, Ola; Johnsen, Roar; Øien, Torbjørn; Rudi, Knut (Peer reviewed; Journal article, 2019) -
Prediction of high fecal propionate-to-butyrate ratios using 16S rRNA-based detection of bacterial groups with liquid array diagnostics
Hiseni, Pranvera; Snipen, Lars-Gustav; Wilson, Robert Charles; Furu, Kari; Hegge, Finn Terje; Rudi, Knut (Peer reviewed; Journal article, 2023)Butyrate and propionate represent two of three main short-chain fatty acids produced by the intestinal microbiota. In healthy populations, their levels are reportedly equimolar, whereas a deviation in their ratio has been ... -
Prevalence and dispersal of a facultative bacterial symbiont associated with an endemic metazoan host
Bakke, Beate Banken; Wilson, Robert Charles; Rudi, Knut (Journal article; Peer reviewed, 2011)Co-dispersal is of primary importance in symbiotic relations between macro- and micro-organisms. Obligate symbionts generally follow the same dispersal pattern as their host, while it still remains unresolved whether ... -
Questioning the Quality of 16S rRNA Gene Sequences Derived From Human Gut Metagenome-Assembled Genomes
Hiseni, Pranvera; Snipen, Lars Gustav; Wilson, Robert Charles; Furu, Kari; Rudi, Knut (Peer reviewed; Journal article, 2022)The recent introduction of metagenome-assembled genomes (MAGs) has marked a major milestone in the human gut microbiome field (Almeida et al., 2019; Nayfach et al., 2019; Pasolli et al., 2019). Such reference-free, de ... -
Spatial fractionation of phosphorus accumulating biofilm: stratification of polyphosphate accumulation and dissimilatory nitrogen metabolism
Villard, Didrik; Saltnes, Torgeir; Sørensen, Gjermund; Angell, Inga Leena; Eikås, Sondre; Johansen, Wenche; Rudi, Knut (Peer reviewed; Journal article, 2022)The spatial distribution of microorganisms represents a critical issue in understanding biofilm function. The aim of the current work was to develop a method for biofilm fractionation, facilitating the analysis of individual ... -
Spatiotemporal succession of phosphorous accumulating biofilms during the first year of establishment
Villard, Didrik; Goa, Inger Andrea Nesbø; Angell, Inga Leena; Eikaas, Sondre; Saltnes, Torgeir; Johansen, Wenche; Rudi, Knut (Peer reviewed; Journal article, 2023)Many wastewater treatment plants are dependent on the utilization of microorganisms in biofilms. Our knowledge about the establishment of these biofilms is limited, particular with respect to biofilms involved in enhanced ...
