Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, Volume 13, Issue 32, 9 June 2026.
Itch‐induced tick removal (IITR): An acquired neuroimmune mechanism, itch‐induced tick removal, develops after repeated tick exposure, mobilizing T cells and macrophages at the tick bite site to trigger a rapid scratching response that facilitates timely tick removal within a critical window that precedes the transmission of many tick‐borne pathogens ...

Rickettsiales in South America: A Systematic Review of Their Molecular Detection and Distribution in Arthropods and Vertebrates

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Bacteria of the order Rickettsiales comprise a diverse group of obligate intracellular microorganisms that are globally distributed and highly prevalent in tropical and subtropical regions. In South America, these bacteria have been associated with arthropod vectors, such as ticks, fleas, mites, lice, and certain dipterans, as well as with a ...

Risk Factors for Tick‐Borne Diseases in Germany: A Scoping Review

Zoonoses and Public Health, Volume 73, Issue 4, Page 297-313, June 2026.
ABSTRACT Tick‐borne diseases (TBDs) have proliferated in Germany. The two most prevalent TBDs, Lyme‐borreliosis and tick‐borne encephalitis, can present with nonspecific symptoms and lead to serious neurological complications. To date, a review synthesising the risk factors of acquiring a TBD in Germany is missing.

Diversity, Host Attachment Preferences and Role of Tick Rhipicephalus microplus in the Transmission of Bartonella spp. and Rickettsia spp. in Cattle From Southern Benin

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Ticks infesting cattle in Southern Benin were investigated for diversity, attachment preferences and zoonotic bacteria. Among 2210 ticks collected from 540 cattle, Rhipicephalus microplus predominated (79.6%). Ticks mainly attached to ears, axillae and trunk. PCR detection revealed Bartonella spp. and Rickettsia spp., highlighting veterinary and public

Bacterial Infections Transmitted by Ticks in Barnaul: Epidemiological and Epizootological Situation, Diagnostic Problems

Эпидемиология и вакцинопрофилактика
Relevance. The Altai Кray with its administrative center, Barnaul, is an endemic region for tick–borne rickettsioses. The contribution of other tick-borne infections (TBI) to the structure of overall morbidity in the subject is significantly lower.
