Characterization of B Cell Responses in Rainbow Trout (Oncorhynchus Mykiss) Affected by Red Mark Syndrome

Advanced Science, Volume 12, Issue 35, September 18, 2025.
This study extensively characterizes the B cell response of rainbow trout (Oncorhynchus mykiss) in response to red mark syndrome (RMS). This disease, suspected to be caused by a Midichloria‐like organism (MLO), induces skin lesions in the infected animals, characterized by a massive influx of IgM+ B cells.

Infection of the endothelium by members of the order Rickettsiales [PDF]

Thrombosis and Haemostasis, 2009
SummaryThe vascular endothelium is the main target of a limited number of infectious agents; Rickettsia, Ehrlichia ruminantium, and Orientia tsutsugamushi are among them. These arthropod-transmitted obligately-intracellular bacteria cause serious systemic diseases that are not infrequently lethal.

Flagellar movement in two bacteria of the family rickettsiaceae: a re-evaluation of motility in an evolutionary perspective. [PDF]

PLoS ONE, 2014
Bacteria of the family Rickettsiaceae have always been largely studied not only for their importance in the medical field, but also as model systems in evolutionary biology. In fact, they share a recent common ancestor with mitochondria. The most studied

Interactions and Community Structure of Fungi and Prokaryotes in Salt and Brackish Marsh Ecosystems

Environmental DNA, Volume 7, Issue 5, September–October 2025.
Microbial communities drive biogeochemical cycling in salt and brackish marshes, yet fungal‐prokaryotic interactions remain understudied. This study used 16S and 28S rRNA metabarcoding and network analyses to examine microbial communities in North Inlet salt marsh and Winyah Bay brackish marsh.

A single-cell genome perspective on studying intracellular associations in unicellular eukaryotes. [PDF]

, 2019
Single-cell genomics (SCG) methods provide a unique opportunity to analyse whole genome information at the resolution of an individual cell. While SCG has been extensively used to investigate bacterial and archaeal genomes, the technique has been rarely ...

Comparison of synthetic membranes in the development of an in vitro feeding system for Dermanyssus gallinae [PDF]

, 2010
Although artificial feeding models for the poultry red mite (Dermanyssus gallinae) most frequently use biological membranes consisting of day-old chick skin, there are ethical considerations associated with the use of skin.

Daphnia‐associated bacterial communities correlate with diet quantity, environmental conditions, and epidemic size across natural outbreaks

Limnology and Oceanography, Volume 70, Issue 8, Page 2053-2066, August 2025.
Abstract Zooplankton‐associated microbiomes play an important role for host health, and contribute to ecosystem processes such as nutrient cycling. Yet, few studies have assessed how environmental gradients and biotic interactions, including parasitism and diet, may shape the microbiome composition of wild zooplankton. Here, we analyzed the microbiomes

Applied and Environmental Microbiology, 2016
ABSTRACT The Rickettsiales ( Alphaproteobacteria ) are obligate intracellular bacteria that colonize a wide range of eukaryotic hosts, including diverse metazoa and protists.

Documenting microbial populations within the University of Alberta Meteorite Curation Facility using 16S rRNA gene sequencing: Implications for the curation of astromaterials

Meteoritics &Planetary Science, Volume 60, Issue 8, Page 1798-1813, August 2025.
Abstract Meteorites are easily contaminated at the Earth's surface by microbial activity. Here, DNA extracts from two meteorite specimens and samples from curation laboratory surfaces are analyzed with amplicon sequencing, to understand microbial communities that contaminate meteorites and that may be resident in curation facilities.
