A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

open access: yesInsect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

open access: yesInsect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

Putting Rodents at the Center of One Health Programs: A Narrative Synthesis

open access: yesIntegrative Zoology, EarlyView.
Rodents link human, animal, and environmental health across diverse ecosystems. Rodent diversity underpins both zoonotic disease risk and ecosystem function. Environmental change reshapes rodent communities and spillover dynamics. Rodents act as reservoirs, amplifiers, and sentinels of emerging pathogens.

The neglected challenge: Vaccination against rickettsiae.

open access: yesPLoS Neglected Tropical Diseases, 2020
Over the last decades, rickettsioses are emerging worldwide. These diseases are caused by intracellular bacteria. Although rickettsioses can be treated with antibiotics, a vaccine against rickettsiae is highly desired for several reasons.

From Data to Knowledge to Wisdom: Lessons Learned From the Vancouver Rat Project

open access: yesIntegrative Zoology, EarlyView.
A synthesis of 15 years of research conducted by the Vancouver Rat Project revealed that: (1) Pathogen ecology within rat colonies is the result of complex interactions among rats, pathogens, and vectors. (2) Local and global population structures influence rat and pathogen ecology.

Rickettsialpox — a rare but not extinct disease: review of the literature and new directions

open access: yesИнфекция и иммунитет, 2020
Rickettsialpox is an urban zoonosis caused by Rickettsia akari. To date R. akari is the only well-characterized mite-borne member of the spotted fever group.

Drivers of Host–Pathogen Community Assemblages in European Forests and Urban Green Spaces

open access: yesIntegrative Zoology, EarlyView.
ABSTRACT Despite advances in understanding infectious diseases, the persistence and re‐emergence of wildlife pathogens continue to raise public and veterinary health concerns. This study investigates the relationship between biodiversity and rodent‐borne diseases in Europe, focusing on habitat alterations and their impact on rodent diversity.

Evidence of Infection in Humans with Rickettsia helvetica in Eastern France

open access: yesEmerging Infectious Diseases, 2000
A 37-year-old man living in eastern France seroconverted to Rickettsia helvetica in August 1997, 4 weeks after the onset of an unexplained febrile illness.

Urban Environments Impact Parasite Diversity and an Antipredator Response in an Amphibian Model

open access: yesIntegrative Zoology, EarlyView.
Urbanization reshapes parasite–host interactions in the amphibian Pelophylax perezi, increasing blood parasite diversity and Lankesterella loads under higher anthropogenic pressure. Urban frogs also show longer flight initiation distances and tibiofibulae, indicating altered antipredator strategies.

Genotyping of Borrelia, Rickettsia and Anaplasma in Ixodes ricinus and Dermacentor reticulatus ticks in the Kaliningrad region

open access: yesЖурнал микробиологии, эпидемиологии и иммунобиологии
Background. Tick-borne bacterial and protozoal pathogens pose a significant public health problem. The aim of this study was to detect and genotype Borrelia, Rickettsia and Anaplasma in Ixodes ricinus and Dermacentor reticulatus ticks collected in the ...
