Assessing the Diversity and Specificity of Two Freshwater Viral Communities through Metagenomics
The two freshwater viromes appear closely related, despite the significant ecological differences between the two lakes, and appear genetically distinct from other aquatic ecosystems, demonstrating the specificity of freshwater viruses at a community scale for the first time. Expand
Exploring and quantifying fungal diversity in freshwater lake ecosystems using rDNA cloning/sequencing and SSU tag pyrosequencing.
This study represents the first unveiling of microbial eukaryote and fungus diversity assessed with two complementary molecular methods, and is considered a major milestone towards understanding the dynamics and ecology of fungi in freshwater lake ecosystems. Expand
The Airway Microbiota in Cystic Fibrosis: A Complex Fungal and Bacterial Community—Implications for Therapeutic Management
The diversity and species richness of fungal and bacterial communities was significantly lower in patients with decreased lung function and poor clinical status, and the microbial community was viewed as a unique pathogenic entity. Expand
Algal diseases: spotlight on a black box.
The biodiversity and impact of pathogens and parasites of aquatic primary producers in freshwater and marine systems are reviewed and how emerging technologies can be used to reassess the profound, multi-faceted, and so far broadly-overlooked influence of algal diseases on ecosystem properties is discussed. Expand
Unveiling fungal zooflagellates as members of freshwater picoeukaryotes: evidence from a molecular diversity study in a deep meromictic lake.
It is thought that fungal zooflagellates have been misidentified as phagotrophic nanoflageLLates in previous studies, in agreement with a recent experimental demonstration that zoospore-producing fungi and parasitic activity may play an important role in aquatic food webs. Expand
Characterization of phytoplankton communities in the lower St. Lawrence Estuary using HPLC-detected pigments and cell microscopy
The seasonal variation in the composition of algal communities in the lower St. Lawrence Estuary was examined using HPLC pigments and cell taxonomy, and the efficiency of these 2 techniques wasExpand
The Molecular Diversity of Freshwater Picoeukaryotes Reveals High Occurrence of Putative Parasitoids in the Plankton
An original 18S rDNA survey of freshwater picoeukaryotes sampled during spring/summer 2005, complementing an earlier study conducted in autumn 2004, highlighted the dominance of parasites and saprotrophs, and provided indications that these organisms have probably been wrongfully regarded as bacterivores in previous studies. Expand
Virus-Bacterium Interactions in Water and Sediment of West African Inland Aquatic Systems
The results support the paradigm that aquatic viruses are ubiquitous and may have moved between the two compartments of the shallow systems examined and indicates that the intensity of virus-bacterium interactions in benthic habitats may lower than the intensity in the adjacent bodies of water. Expand
Dysbiosis in inflammatory bowel disease: a role for bacteriophages?
The dysbiosis theory, reviewed by Tamboli et al, is that an imbalance between putative “harmful” versus “protective” bacterial species may promote chronic intestinal inflammation, and several studies published so far support this hypothesis. Expand
Viral Activity in Two Contrasting Lake Ecosystems
Although viruses did not represent the main agent of bacterial mortality, their relative importance was higher in the less productive system, and there were no significant depth-related differences in FVIC or burst size. Expand
