Ehrlichia chaffeensis proteomic profiling reveals distinct expression patterns of infectious and replicating forms

Frontiers in Cellular and Infection Microbiology
Ehrlichia chaffeensis is a tick-transmitted rickettsial pathogen responsible for causing human monocytic ehrlichiosis (HME). The pathogen’s developmental cycle includes infectious dense-core cells (DCs) and non-infectious replicating cells (RCs ...

A 10-year surveillance of Rickettsiales (Rickettsia spp. and Anaplasma phagocytophilum) in the city of Hanover, Germany, reveals Rickettsia spp. as emerging pathogens in ticks

Parasites & Vectors, 2017
Background Rickettsiales (Rickettsia spp. and Anaplasma phagocytophilum) transmitted by ticks are considered (re-)emerging pathogens posing a risk to public health.

Symbiosis in an overlooked microcosm: a systematic review of the bacterial flora of mites [PDF]

, 2015
A dataset of bacterial diversity found in mites was compiled from 193 publications (from 1964 to January 2015). A total of 143 mite species belonging to the 3 orders (Mesostigmata, Sarcoptiformes and Trombidiformes) were recorded and found to be ...

Environmental Metagenomic Assemblies Reveal Seven New Highly Divergent Chlamydial Lineages and Hallmarks of a Conserved Intracellular Lifestyle

Frontiers in Microbiology, 2018
The Chlamydiae phylum exclusively encompasses bacteria sharing a similar obligate intracellular life cycle. Existing 16S rDNA data support a high diversity within the phylum, however genomic data remain scarce owing to the difficulty in isolating strains

The genome and stage‐specific transcriptomes of the carrot weevil, Listronotus oregonensis, reveal adaptive mechanisms for host specialisation and symbiotic interactions

Insect Molecular Biology, EarlyView.
Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

A novel extracellular gut symbiont in the marine worm Priapulus caudatus (Priapulida) reveals an alphaproteobacterial symbiont clade of the Ecdysozoa

Frontiers in Microbiology, 2016
Priapulus caudatus (phylum Priapulida) is a benthic marine predatory worm with a cosmopolitan distribution. In its digestive tract we detected symbiotic bacteria that were consistently present in specimens collected over eight years from three sites at ...

Comparative susceptibility of mosquito populations in North Queensland, Australia to oral infection with dengue virus. [PDF]

, 2014
Dengue is the most prevalent arthropod-borne virus, with at least 40% of the world's population at risk of infection each year. In Australia, dengue is not endemic, but viremic travelers trigger outbreaks involving hundreds of cases.

A comparison of super‐resolution microscopy techniques for imaging tightly packed microcolonies of an obligate intracellular bacterium

Journal of Microscopy, EarlyView.
Abstract Conventional optical microscopy imaging of obligate intracellular bacteria is hampered by the small size of bacterial cells, tight clustering exhibited by some bacterial species and challenges relating to labelling such as background from host cells, a lack of validated reagents, and a lack of tools for genetic manipulation.

Detection of Anaplasma phagocytophilum and Babesia aktasi in a wild bezoar goat (Capra aegagrus): Overlap with domestic goat strains

Medical and Veterinary Entomology, EarlyView.
This study provides the first molecular detection of tick‐borne pathogens in Capra aegagrus. Genetic analysis reveals similarities between Babesia aktasi and Anaplasma phagocytophilum strains in bezoar and domestic goats, indicating potential pathogen exchange.

Parallelisms and Contrasts in the Diverse Ecologies of the Anaplasma phagocytophilum and Borrelia burgdorferi Complexes of Bacteria in the Far Western United States. [PDF]

, 2016
Anaplasma phagocytophilum and Borrelia burgdorferi are two tick-borne bacteria that cause disease in people and animals. For each of these bacteria, there is a complex of closely related genospecies and/or strains that are genetically distinct and have ...
