Improved Detection and Sequencing of Rickettsia spp. DNA in South African Wildlife

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Nested gltA PCR detected Rickettsia spp. DNA in 44% of South African wildlife samples previously negative by RLB, revealing spotted fever, typhus and transitional group lineages, novel host records, co‐infection and multi‐organ dissemination in impala, highlighting complex wildlife involvement and zoonotic risk within a One Health framework.

Data_Sheet_1_Diversity of Rickettsiales bacteria in five species of ticks collected from Jinzhai County, Anhui Province, China in 2021–2022.docx

, 2023
The order Rickettsiales in the class Alphaproteobacteria comprises vector-borne pathogens of both medical and veterinary importance. Ticks, as a group, are second only to mosquitoes as vectors of pathogens to humans, playing a critical role in the ...

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 ...

Reduced fecundity associated with Wolbachia infection in a Neotropical drosophilid Redução da fecundidade associada à infecção por Wolbachia em um drosofilídeo Neotropical

Ecological Entomology, Volume 51, Issue 3, Page 475-488, June 2026.
Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.

The Elusive Fraction of Marine Plankton Diversity: Size, Abundance and Taxonomic Composition of 0.2 μm‐Filterable Prokaryotes Across Three Contrasting Coastal Environments

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The existence of prokaryotes escaping filtration through 0.2‐μm filters has been known for decades. Such ‘filterable’ prokaryotes (hereafter ‘FP’) might include true ultra‐small groups (i.e., ultramicrobacteria), but also cells that miniaturize temporally as a physiological strategy to persist under unfavourable conditions, representing a ...

Risk Factors for Tick‐Borne Diseases in Germany: A Scoping Review

Zoonoses and Public Health, Volume 73, Issue 4, Page 297-313, June 2026.
ABSTRACT Tick‐borne diseases (TBDs) have proliferated in Germany. The two most prevalent TBDs, Lyme‐borreliosis and tick‐borne encephalitis, can present with nonspecific symptoms and lead to serious neurological complications. To date, a review synthesising the risk factors of acquiring a TBD in Germany is missing.

Biodiversity of “Non-model” Rickettsiales and Their Association with Aquatic Organisms

, 2016
Representatives of the order Rickettsiales are obligate intracellular bacteria, traditionally including well-studied pathogens of humans and other vertebrates, such as Rickettsia, Orientia, Anaplasma, and Ehrlichia. In the last two decades, studies based

Peptidoglycan In Orientia tsutsugamushi And Other Rickettsiales Species [PDF]

, 2019
Orientia tsutsugamushi is an obligate intracellular bacterium which causes the neglected human disease scrub typhus. The cell biology of Orientia is relatively poorly studied compared to other human pathogens of equivalent severity and prevalence. Due to

Comparative Genomic Analysis of Holospora spp., Intranuclear Symbionts of Paramecia

Frontiers in Microbiology, 2018
While most endosymbiotic bacteria are transmitted only vertically, Holospora spp., an alphaproteobacterium from the Rickettsiales order, can desert its host and invade a new one.

Molecular Phylogeny and Strain Genotyping of the Bacterial Endosymbiont Wolbachia Associated With Tuta absoluta Populations

Entomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 387-397, May 2026.
This study was designed to understand the association between reproductive endosymbiotic bacteria and wild and laboratory‐reared Tuta absoluta populations. The majority of T. absoluta populations showed Wolbachia presence at varying levels of infection, whereas Arsenophonus, Cardinium, and Spiroplasma were not detected. Wolbachia‐positive T.
