Exotic Rickettsiae in Ixodes ricinus: fact or artifact? [PDF]

open access: yes, 2010
Several pathogenic Rickettsia species can be transmitted via Ixodes ricinus ticks to humans and animals. Surveys of I. ricinus for the presence of Rickettsiae using part of its 16S rRNA gene yield a plethora of new and different Rickettsia sequences ...

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

open access: yesInsect 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

Parallel decline of malaria and Rickettsia felis infections in Senegal

open access: yes, 2018
Rickettsia felis is a common emerging pathogen in sub-Saharan Africa. Comparing dynamics of morbidities due to malaria and R. felis infections in two Senegalese villages, we found a strong and significant correlation between them.

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.

Male-killing bacteria in insects: mechanisms, incidence and implications

open access: yes, 2000
Bacteria that are vertically transmitted through female hosts and kill male hosts that inherit them were first recorded in insects during the 1950s. Recent studies have shown these "male-killers" to be diverse and have led to a reappraisal of the biology

Pathogenicity and virulence of Rickettsia

open access: yesVirulence, 2022
Rickettsiae include diverse Gram-negative microbial species that exhibit obligatory intracellular lifecycles between mammalian hosts and arthropod vectors.

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.

Murine Typhus and Leptospirosis as Causes of Acute Undifferentiated Fever, Indonesia [PDF]

open access: yes, 2009
To investigate rickettsioses and leptospirosis among urban residents of Semarang, Indonesia, we tested the blood of 137 patients with fever. Evidence of Rickettsia typhi, the agent of murine typhus, was found in 9 patients.

An Atypical Skin Presentation of Adult‐Onset Still's Disease With Histological Description: A Case Report

open access: yesJournal of Cutaneous Pathology, EarlyView.
ABSTRACT Adult‐onset Still's disease (AOSD) is an auto inflammatory disorder with a variable clinical presentation, and without a pathognomonic diagnostic test, characterized by high spiking fever, arthralgia/arthritis, a suggestive skin rash, elevated white blood cell count 10 G/L (> 80% neutrophils), elevated ferritin, with glycosylated ferritin < 20%

Survey of vector-borne agents in feral cats and first report of Babesia gibsoni in cats on St Kitts, West Indies

open access: yesBMC Veterinary Research, 2017
Background As there is little data on vector-borne diseases of cats in the Caribbean region and even around the world, we tested feral cats from St Kitts by PCR to detect infections with Babesia, Ehrlichia and spotted fever group Rickettsia (SFGR) and ...
