Attempted transmission of human granulocytotropic Ehrlichia (HGE) by Amblyomma americanum and Amblyomma maculatum

Veterinary Parasitology, 1997
Transstadial transmission of human granulocytotrophic Ehrlichia (HGE) was attempted in dogs using Amblyomma americanum (L.) and A. maculatum Koch, two species that, as adults, feed readily on human beings. Larvae and nymphs were acquisition-fed on a dog that was parasitemic with HGE.

Evaluation of Human Attachment by LarvalAmblyomma maculatum(Acari: Ixodidae)

Journal of Medical Entomology, 2015
The tick, Amblyomma maculatum Koch (Gulf Coast tick), has recently been shown to be an important disease vector of both medical and veterinary concern. Although much is known about the behavior and ecology of adults, little is known of the immatures. Larval feeding on humans has never been demonstrated (and thus, there are no collection records from ...

Tick Paralysis Caused by Amblyomma maculatum on the Mexican Pacific Coast

Vector-Borne and Zoonotic Diseases, 2011
Tick paralysis is a rare entity in which it is necessary to identify the cause and remove the arthropod to have a rapid remission of symptoms. In the absence of an early diagnosis, the outcome can be fatal, as toxins are released from the tick's saliva as it feeds.

Detection of Amblyomma maculatum and Rickettsia parkeri in prairies of Central Missouri

Veterinary Parasitology: Regional Studies and Reports
The destruction and decline of prairie habitats due to landscape repurposing have profoundly impacted the diversity of plant, animal, and insect life. In the Central United States, the reconstruction of prairie habitats from farmland is a widely applied strategy to raise diversity and recreate a healthy, complex ecosystem.

Response of Ovipositing Amblyomma Maculatum Koch (Acarina: Ixodidae) to Photoperiod

Journal of Medical Entomology, 1971
When engorged females of the Gulf Coast tick, Amblyomma maculalum Koch, were exposed to 4 photoperiodic regimens at constant conditions of 27°C and 80% RH, the patterns of daily oviposition of those exposed to the shortest (1/4 hr) and longest (16 hr) light periods differed significantly from the patterns of those exposed to light periods of 8 and 12 ...

Mate-seeking by Female Amblyomma maculatum (Acarina: Ixodidae) on a Bovine

Nature, 1971
LITTLE information is available concerning the attraction between sexes of ticks, and the literature contains no reports of sex pheromones in these arachnids. In some tick species the males are known to seek the attached females1–4, though male bont ticks, Amblyomma hebraeum Koch, in Africa probably attract females5.

Feeding predilection of Gulf Coast tick, Amblyomma maculatum Koch, nymphs on cattle

Veterinary Parasitology, 2005
Gulf Coast tick nymphs successfully attached and fed on cattle after being freely released. Six Hereford heifers were each infested with approximately 2000 Gulf Coast tick nymphs, three with a strain originating from Refugio Co., TX, and three with ticks from Osage Co., KS by free release on the head and legs to simulate field acquisition of questing ...

Specifying Pathogen Associations ofAmblyomma maculatum(Acari: Ixodidae) in Western Tennessee

Journal of Medical Entomology, 2016
Amblyomma maculatum Koch (Acari: Ixodidae) is established in western Tennessee, a region with increased risk for Rocky Mountain spotted fever and ehrlichiosis. This tick transmits Rickettsia parkeri to humans, likely contributing to cases of rickettsiosis in the region.

Drivers of behavior in two tick species, Amblyomma americanum and Amblyomma maculatum (Acari: Ixodidae), in a laboratory setting

Journal of Vector Ecology
Ticks and tick-borne diseases are of increasing concern in the United States, and understanding tick behavior could be crucial to limiting the exposure of humans and other animals to ticks. Here, we wanted to understand the drivers of questing and burrowing in Amblyomma americanum and A. maculatum.
