Haemophagocytic lymphohistiocytosis triggered by Rickettsia conorii

Transactions of the Royal Society of Tropical Medicine and Hygiene
Abstract Haemophagocytic lymphohistiocytosis (HLH) is a rare complication of rickettsial infections. We report a 50-y-old man from northern India who presented with fever, respiratory distress, altered sensorium and an eschar. Despite treatment with doxycycline, his condition deteriorated with multi-organ dysfunction.

Pet and Stray Dogs’ Contribution to Zoonotic Transmission Pathways: A Bibliometric Review

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Based on a large‐scale bibliometric dataset, domestic dogs (Canis lupus familiaris) emerge as the most frequently cited host species in the context of zoonoses, being mentioned in at least 10% of publications for nearly a quarter of the pathogens recognized as zoonotic to humans.

Optimization of heat inactivation protocols for Orientia and Rickettsia species

Scientific Reports
Heat treatment, or thermal disinfection, is one of the simplest and most widely used methods for microbial inactivation. Proper heat inactivation protocols are essential to ensure the safe transportation and handling of infectious materials, particularly

Ticks and Tick‐Borne Pathogens Encountered by Dogs and Cats: A North European Perspective

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Climate change is increasing the worldwide burden of tick‐borne diseases (TBDs). Dramatic increases in human cases of borreliosis have been reported during the past few decades, including from Finland, located in North Europe. As human exposure to ticks carrying pathogens is increasing, so likely is exposure of dogs and cats.

Hyalomma marginatum in Europe: The Past, Current Status, and Future Challenges—A Systematic Review

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Hyalomma marginatum is a prominent tick vector responsible for transmitting various pathogens, including the Crimean–Congo hemorrhagic fever virus (CCHFV), across Europe. This systematic review consolidates findings from 144 publications regarding the geographical distribution of H. marginatum and its associated pathogens.

First molecular diagnosis of the human pathogen Rickettsia raoultii and other spotted fever group rickettsiae in Sudanese ixodid ticks from domestic ruminants

Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.
In this manuscript, the authors collected ixodid ticks and examined the presence of Rickettsia species by PCR. By performing sequencing and phylogenetic analysis, the authors identified the presence of four different Rickettsia species in three tick species found on three mammalian hosts.

Rickettsia disrupts and reduces endothelial tight junction protein zonula occludens-1 in association with inflammasome activation

Infection and Immunity
Rickettsia spp. cause life-threatening diseases in humans. The fundamental pathophysiological changes in fatal rickettsial diseases are disrupted endothelial barrier and increased microvascular permeability.
