Accelerated phenology of blacklegged ticks under climate warming [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 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

A Dispersal Model for the Range Expansion of Blacklegged Tick (Acari: Ixodidae) [PDF]

Journal of Medical Entomology, 2004
The blacklegged tick, Ixodes scapularis Say, a vector for the agents of Lyme borreliosis and other diseases, has expanded its range dramatically over the past 20 yr. However, the relative contributions of different vertebrate host species to this expansion have remained largely unexplored.

Human pathogens associated with the blacklegged tick Ixodes scapularis: a systematic review. [PDF]

Parasit Vectors, 2016
The blacklegged tick Ixodes scapularis transmits Borrelia burgdorferi (sensu stricto) in eastern North America; however, the agent of Lyme disease is not the sole pathogen harbored by the blacklegged tick. The blacklegged tick is expanding its range into areas of southern Canada such as Ontario, an area where exposure to blacklegged tick bites and tick-

Exposure to Tick-Borne Pathogens in Cats and Dogs Infested With Ixodes scapularis in Quebec: An 8-Year Surveillance Study

Frontiers in Veterinary Science, 2021
Cats that spend time outdoors and dogs are particularly at risk of exposure to ticks and the pathogens they transmit. A retrospective study on data collected through passive tick surveillance was conducted to estimate the risk of exposure to tick-borne ...

Seasonality in Diurnal Locomotory Patterns of Adult Blacklegged Ticks (Acari: Ixodidae) [PDF]

Journal of Medical Entomology, 2005
We continuously recorded the activity of adult and nymphal blacklegged ticks, Ixodes scapularis Say, exposed to diurnal light and temperature cycles in a laboratory test chamber by using a digital camera controlled by an intervalometer. Adult ticks collected and tested in the fall exhibited a bimodal pattern of activity, with peaks shortly after lights

Dispersal of Blacklegged Tick (Acari: Ixodidae) Nymphs and Adults at the Woods–Pasture Interface [PDF]

Journal of Medical Entomology, 1996
Marked nymphal and adult blacklegged ticks, Ixodes scapularis Say, were released in 4 host-exclusion cages and 4 similar control areas, all straddling the woods-pasture interface. Both nymphs and adults were recaptured by flagging at regular intervals outside the cages, having therefore actively dispersed > 4.5 m (i.e., without involvement of ...

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

Journal of Medical Entomology, 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 (

Tick Densities and Infection Prevalence on Coastal Islands in Massachusetts, USA: Establishing a Baseline

Insects, 2023
Tick-borne diseases and a tick-induced red meat allergy have become increasingly common in the northeastern USA and elsewhere. At the scale of local communities, few studies have documented tick densities or infection levels to characterize current ...

Cryptic Genes for Interbacterial Antagonism Distinguish Rickettsia Species Infecting Blacklegged Ticks From Other Rickettsia Pathogens

Frontiers in Cellular and Infection Microbiology, 2022
BackgroundThe genus Rickettsia (Alphaproteobacteria: Rickettsiales) encompasses numerous obligate intracellular species with predominantly ciliate and arthropod hosts.

Bunyaviruses are common in male and female Ixodes scapularis ticks in central Pennsylvania [PDF]

PeerJ, 2016
The blacklegged tick Ixodes scapularis is widely distributed in the United States and transmits multiple pathogens to humans, wildlife and domestic animals. Recently, several novel viruses in the family Bunyaviridae (South Bay virus (SBV) and Blacklegged
