Cutaneous Pseudolymphomas With Identical Clinicopathological Features Induced by Tick Bites at Two Separate Sites

Clinical Case Reports, Volume 13, Issue 8, August 2025.
ABSTRACT Identical dermoscopic and histopathologic findings at two distinct tick bite sites demonstrate a stereotypical immune response within a single individual of cutaneous pseudolymphoma, with diagnostic clues including retained cement cones and white reticular lines, even in the absence of visible tick parts.

Reptile-associated Borrelia species in the goanna tick (Bothriocroton undatum) from Sydney, Australia

Parasites & Vectors, 2017
BackgroundKnowledge on the capacity of Australian ticks to carry Borrelia species is currently limited or missing. To evaluate the potential of ticks to carry bacterial pathogens and their DNA, it is imperative to have a robust workflow that maximises ...

Surgical Removal of a Tick‐Bite Region Without the Presence of an Insect Body

Clinical Case Reports, Volume 13, Issue 8, August 2025.
Surgical excision of a tick‐bite lesion revealed retained mouthparts despite the absence of a visible tick body. Dermoscopy demonstrated chelicerae imprints, and histopathology confirmed the presence of residual tick structures. This case highlights the combined diagnostic value of dermoscopy and histopathology in cases where the tick body is not found.

There is inadequate evidence to support the division of the genus Borrelia.

International Journal of Systematic and Evolutionary Microbiology, 2017
There are surely scientific, genetic or ecological arguments which show that differences exist between the relapsing fever (RF) spirochaetes and the Lyme borreliosis (LB) group of spirochaetes, both of which belong to the genus Borrelia.

Reappraisal of the Dilution and Amplification Effect Framework: A Case Study in Lyme Disease

Ecology and Evolution, Volume 15, Issue 8, August 2025.
The biodiversity–disease relationship posits two hypotheses: the dilution effect (where there's a negative relationship between biodiversity and disease risk) and the amplification effect (where there's a positive relationship). However, the literature has historically treated these hypotheses as either/or, ignoring the potential for a null result.

Behavioral and Morphological Adaptations of Tortoise Tick Hyalomma aegyptium to Testudo graeca: Evidence for Complex Evolutionary History

Ecology and Evolution, Volume 15, Issue 8, August 2025.
In this study, we examined the infestation characteristics of the tick species Hyalomma aegyptium on its specific host, the spur‐thighed tortoise Testudo graeca, to investigate the principles of behavioral and morphological adaptation and its ecological consequences.

Ticks and tick-borne pathogens on Belle-Île-en-Mer: An exploratory study in a western French island environment

Ticks and Tick-Borne Diseases
The islands of Brittany provide unique ecosystems for ticks and tick-borne diseases owing to their oceanic climate, influencing interactions among ticks, hosts, and pathogens.

Borrelia lanei sp. nov. extends the diversity of Borrelia species in California.

International Journal of Systematic and Evolutionary Microbiology, 2017
The diversity of Borrelia species discovered in California appears to be particularly high. A divergent group of Borrelia strains collected from Ixodes ticks in California was described by Postic and co-workers and designated 'genomospecies 2' (Postic D,
