The host calcium system contributes to intracellular Rickettsia pathogenesis

Infection and Immunity
Bacteria in the genus Rickettsia are obligate intracellular parasites of the eukaryotic cytoplasm. Pathogenic Rickettsia species are exquisitely evolved to only proliferate within eukaryotic host cells, particularly within endothelial cells of the ...

Exploring the potential of using male‐killing endosymbionts to induce female‐biased insect populations for enhanced biomass production

Insect Science, EarlyView.
Overview of the mindset and long‐term goals with the approach suggested in this study. We provide a first proof of concept that male‐killing endosymbionts can be used to establish female biased populations with higher production efficiency than populations with a 50/50 sex ratio. This biological tool can have marked positive impact on future commercial

Amblyomma imitator Ticks as Vectors of Rickettsia rickettsii, Mexico

Emerging Infectious Diseases, 2010
Real-time PCR of Amblyomma imitator tick egg masses obtained in Nuevo Leon State, Mexico, identified a Rickettsia species. Sequence analyses of 17-kD common antigen and outer membrane protein A and B gene fragments showed to it to be R. rickettsii, which

Rickettsia lusitaniae in Ornithodoros Porcinus Ticks, Zambia

Pathogens, 2021
Rickettsial pathogens are amongst the emerging and re-emerging vector-borne zoonoses of public health importance. Though traditionally considered to be transmitted by ixodid ticks, the role of argasid ticks as vectors of these pathogens is increasingly ...

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

Integrative 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.

Rickettsia gravesii sp. nov.: a novel spotted fever group rickettsia in Western Australian Amblyomma triguttatum triguttatum ticks

, 2017
A rickettsial organism harboured by Amblyomma triguttatum ticks on Barrow Island, Western Australia, was discovered after reports of possible rickettsiosis among local workers.

Diversity of Rickettsia species in collected ticks from Southeast Iran

BMC Veterinary Research
Rickettsia occurs worldwide and rickettsiosis is recognized as an emerging infection in several parts of the world. Ticks are reservoir hosts for pathogenic Rickettsia species in humans and domestic animals.

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

Integrative 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.
