Efficacy of afoxolaner against Ixodes scapularis ticks in dogs

Veterinary Parasitology, 2014
Efficacy of afoxolaner, a novel isoxazoline insecticide/acaricide, against Ixodes scapularis was evaluated in a laboratory study. One day prior to treatment, beagle dogs (n=16) were infested with 50 unfed wild adult ticks. Repeat infestations were performed weekly for four additional weeks.

Contrasting epigenetics of Ixodes scapularis populations

Abstract Hard ticks are a source of public health concern, in part due to their ability to inhabit different environmental regions, which increases human encounters. In the United States (US), blacklegged ticks (Ixodes scapularis Say), the primary vector of Lyme disease, exhibit various phenotypes depending on their geographic origin (i.e ...

Increasing Prevalence of Borrelia burgdorferi sensu stricto–Infected Blacklegged Ticks in Tennessee Valley, Tennessee, USA

Emerging Infectious Diseases, 2018
In 2017, we surveyed forests in the upper Tennessee Valley, Tennessee, USA. We found Ixodes scapularis ticks established in 23 of 26 counties, 4 of which had Borrelia burgdorferi sensu stricto–infected ticks.

Single-tube real-time PCR assay for differentiation of Ixodes affinis and Ixodes scapularis

Ticks and Tick-borne Diseases, 2014
Ixodes affinis Neumann (1899) and Ixodes scapularis Say (1821) are tick vectors of the etiologic agent of Lyme disease, Borrelia burgdorferi sensu stricto. Ixodes affinis and I. scapularis are morphologically very similar, and as they are sympatric in the mid- and south-Atlantic U.S.

The role of Rab27 in tick extracellular vesicle biogenesis and pathogen infection

Parasites & Vectors
Background The blacklegged tick, Ixodes scapularis, transmits most vector-borne diseases in the US. It vectors seven pathogens of public health relevance, including the emerging human pathogen Anaplasma phagocytophilum.

Ticking Time Bomb? Climate Change and Ixodes scapularis

Environmental Health Perspectives, 2014
Lyme disease, caused by the bacterium Borrelia burgdorferi, first emerged in the northeastern United States in the 1970s.1 Since then, the geographic range of the illness has expanded to the west, south, and north, and it has become by far the most commonly reported vector-borne disease in North America.2 Evidence is mounting that, on its northern ...

Seasonal activity patterns of Ixodes scapularis and Ixodes pacificus in the United States

Ticks and Tick-borne Diseases
Knowledge of seasonal activity patterns of human-biting life stages of tick species serving as vectors of human disease agents provides basic information on when during the year humans are most at risk for tick bites and tick-borne diseases. Although there is a wealth of published information on seasonal activity patterns of Ixodes scapularis and ...
