Whole Genome Sequencing Reveals Clade-Specific Genetic Variation in Blacklegged Ticks. [PDF]

Ecol Evol
Ticks and tick‐borne pathogens represent the greatest vector‐borne disease threat in the United States. Blacklegged ticks are responsible for most human cases, yet the disease burden is unevenly distributed across the northern and southern United States.

Phylogeographic dynamics of the arthropod vector, the blacklegged tick (Ixodes scapularis) [PDF]

Parasites & Vectors, 2022
Background The emergence of vector-borne pathogens in novel geographic areas is regulated by the migration of their arthropod vectors. Blacklegged ticks (Ixodes scapularis) and the pathogens they vector, including the causative agents of Lyme disease ...

Tick-Borne Pathogens in Questing Blacklegged Ticks (Acari: Ixodidae) From Pike County, Pennsylvania. [PDF]

J Med Entomol, 2022
Abstract Active surveillance was conducted by collecting questing ticks from vegetation through a 2-yr survey in Pike County, Pennsylvania. Over a thousand blacklegged ticks (Ixodes scapularis Say) and American dog ticks (Dermacentor variabilis Say) were collected. A single specimen of the following species was collected: lone star tick (

Accelerated phenology of blacklegged ticks under climate warming. [PDF]

Philos Trans R Soc Lond B Biol Sci, 2015
The phenology of tick emergence has important implications for the transmission of tick-borne pathogens. A long lag between the emergence of tick nymphs in spring and larvae in summer should increase transmission of persistent pathogens by allowing infected nymphs to inoculate the population of naive hosts that can subsequently transmit the pathogen to

The Spread of Lone Star Ticks (<i>Amblyomma americanum</i>) and Persistence of Blacklegged Ticks (<i>Ixodes scapularis</i>) on a Coastal Island in Massachusetts, USA. [PDF]

Insects
In the northeastern USA, the distribution of lone star ticks (Amblyomma americanum) has expanded northward in recent decades, overlapping with the range of blacklegged ticks (Ixodes scapularis). Blacklegged ticks carry pathogens for diseases such as Lyme,

Circadian regulation of locomotion, respiration, and arousability in adult blacklegged ticks (Ixodes scapularis). [PDF]

Sci Rep
The blacklegged tick, Ixodes scapularis, is an ectoparasitic arachnid and vector for infectious diseases, including Lyme borreliosis. Here, we investigate the diurnal activity and respiration of wild-caught and lab-reared adult ticks with long-term video

Influences of Host Community Characteristics on Borrelia burgdorferi Infection Prevalence in Blacklegged Ticks. [PDF]

PLoS One, 2017
Lyme disease is a major vector-borne bacterial disease in the USA. The disease is caused by Borrelia burgdorferi, and transmitted among hosts and humans, primarily by blacklegged ticks (Ixodes scapularis). The ~25 B.

Effects of residential acaricide treatments on patterns of pathogen coinfection in blacklegged ticks. [PDF]

Parasitology
Medically important ixodid ticks often carry multiple pathogens, with individual ticks frequently coinfected and capable of transmitting multiple infections to hosts, including humans.

Passive Surveillance of SARS-CoV-2 in Adult Blacklegged Ticks (Ixodes scapularis) from Northeast Pennsylvania. [PDF]

Life (Basel), 2023
Monitoring the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in wildlife is vital to public health. White-tailed deer (Odocoileus virginianus) in the United States have tested positive for SARS-CoV-2, and their interactions with ...

Population-based passive tick surveillance and detection of expanding foci of blacklegged ticks Ixodes scapularis and the Lyme disease agent Borrelia burgdorferi in Ontario, Canada. [PDF]

PLoS ONE, 2014
We identified ticks submitted by the public from 2008 through 2012 in Ontario, Canada, and tested blacklegged ticks Ixodes scapularis for Borrelia burgdorferi and Anaplasma phagocytophilum. Among the 18 species of ticks identified, I.
