Morphological Abnormalities and Biological Effects in the Porto Alegre Strain of Rhipicephalus microplus

Entomological Research, Volume 56, Issue 3, March 2026.
ABSTRACT Rhipicephalus microplus is a widespread tick species causing significant economic losses and transmitting pathogens to cattle. The R. microplus populations utilized in tick research are frequently maintained under laboratory conditions for many years.

Microevolution of tick-borne encephalitis virus in course of host alternation [PDF]

, 2007
Two tick-borne encephalitis (TBE) virus variants were studied: mouse brain-adapted strain EK-328 and its derivate adapted to Hyalomma marginatum ticks.

Distribution of Ticks and Prevalence of Tick‐Borne Pathogens in Multiple Regions of China

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Ticks and tick‐borne pathogens pose significant threats to livestock and public health. While tick occurrences have been reported in China, systematic assessments of pathogen risk factors across diverse hosts and regions remain limited. This study investigated tick distribution, prevalence, and associated pathogen infections across seven sampling sites

Genetic diversity of Salp15 in the Ixodes ricinus complex (Acari: Ixodidae).

PLoS ONE, 2014
Salp15, a 15-kDa tick salivary gland protein, is both essential for ticks to successfully obtain host blood and also facilitates transmission of Lyme borreliosis. To determine whether the Salp15 gene is expressed in Ixodes persulcatus and Ixodes sinensis,

Ecological and Epidemiological Consequences of Tick‐Control Interventions in Residential Neighborhoods: A Synthesis of The Tick Project

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Controlling populations of Ixodes ticks has emerged as a core strategy for reducing human exposure to tick‐borne infections. Several means of reducing the size of the tick population using chemical and biological acaricides show promise in field trials and are frequently used commercially in North America and Europe.

Modeling the effects of variable feeding patterns of larval ticks on the transmission of Borrelia lusitaniae and Borrelia afzelii [PDF]

, 2017
Spirochetes belonging to the Borrelia burgdoferi sensu lato (sl) group cause Lyme Borreliosis (LB), which is the most commonly reported vector-borne zoonosis in Europe. B. burgdorferi sl is maintained in nature in a complex cycle involving Ixodes ricinus

Phylogeographical structure of the tick Ixodes persulcatus: A novel view

Ticks and Tick-borne Diseases, 2012
The tick Ixodes persulcatus Schulze, 1930, has a wide distribution from the Baltic to the Far East and is a vector of a number of human pathogens. Thus, the study of the genetic structure and evolution of this species is of great epidemiological importance. rRNA genes were used as genetic markers to identify the phylogeographical structure of the ticks.
