Amblyomma cajennense (Fabricius, 1787) (Acari: Ixodidae), the Cayenne tick: phylogeography and evidence for allopatric speciation [PDF]

, 2013
Background: Amblyomma cajennense F. is one of the best known and studied ticks in the New World because of its very wide distribution, its economical importance as pest of domestic ungulates, and its association with a variety of animal and human ...

Variable effects of wildlife and livestock on questing tick abundance across a topographical–climatic gradient

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract Large‐bodied wild ungulates are declining worldwide, while domestic livestock continue to increase in abundance. Such changes in large herbivore communities should have strong effects on the control of ticks and tick‐borne disease as they can indirectly modify habitat and directly serve as final hosts for ticks' lifecycles.

Identification and characterization of proteins in the Amblyomma americanum tick cement cone [PDF]

International Journal for Parasitology, 2018
The adaptation of hard ticks to feed for long periods is facilitated by the cement cone, which securely anchors the tick mouthparts onto host skin and protects the tick from being groomed off by the host. Thus, preventing tick cement deposition is an attractive target for the development of innovative tick control.

Geographic Variation in the Prevalence of Candidatus Neoehrlichia procyonis in Raccoons (Procyon lotor) in the United States and Canada

MicrobiologyOpen, Volume 14, Issue 1, February 2025.
A total of 167/394 (42.4%) raccoons were positive for Candidatus Neoehrlichia procyonis. Spatial variation was noted with higher prevalences in the Southeast region of the United States and in California. Ca. N. procyonis is widespread in raccoon populations, but the spatial variation in prevalence may be related to vector distribution or another ...

The effects of vegetation density and habitat disturbance on the spatial distribution of ixodid ticks (Acari: Ixodidae) [PDF]

, 2008
Larval, nymphal, and adult Amblyomma americanum (L.), and adult Dermacentor variabilis (Say) ticks were collected using timed dragging techniques, in an attempt to examine how different habitat variables affect models that describe the distribution of ...

New Jersey-Wide Survey of Rickettsia (Proteobacteria: Rickettsiaceae) in Dermacentor variabilis and Amblyomma americanum (Acari: Ixodida: Ixodidae).

American Journal of Tropical Medicine and Hygiene, 2020
For the last decade, the New Jersey (NJ) Department of Health has reported between 42 and 144 new cases each year of "spotted fever group rickettsiosis" (SFGR), a statistic that reflects uncertainty regarding which rickettsial agents (Proteobacteria ...

Individual variation underlies large‐scale patterns: Host conditions and behavior affect parasitism

Ecology, Volume 106, Issue 1, January 2025.
Abstract Identifying the factors that affect host–parasite interactions is essential for understanding the ecology and dynamics of vector‐borne diseases and may be an important component of predicting human disease risk. Characteristics of hosts themselves (e.g., body condition, host behavior, immune defenses) may affect the likelihood of parasitism ...

Quelques observations sur une souche de Cowdria ruminantium isolée en Guadeloupe (Antilles françaises) [PDF]

, 1985
Une souche de Cowdria ruminantium isolée en Guadeloupe (Antilles) a été comparée, dans des tests d'immunité croisée chez des petits ruminants, à la souche de référence sud-africaine "Ball 3", à une souche du Soudan("Umm Banein") et à une souche sud ...
