Amblyomma americanum

2023
3. Amblyomma americanum (Linnaeus, 1758). Nearctic: 1) USA (Lado et al. 2020). Although Camicas et al. (1998) treated Amblyomma americanum as a Nearctic and Neotropical species, Guglielmone et al. (2003, 2014, 2021) listed and discussed several records of this tick from Neotropical countries and a few from other zoogeographic regions, including Russia (

Vesicular Eruption Secondary to Bites by Larval Amblyomma americanum

Cutis, 2022
Tick-borne illness is an increasingly concerning cause of human infectious disease. Not only do ticks transmit disease, but their bites also may cause impressive local reactions. This report highlights a case of a widespread vesicular eruption secondary to bites by larval Amblyomma americanum sustained by a 58-year-old woman.

Rickettsia amblyommiiInfectingAmblyomma americanumLarvae

Vector-Borne and Zoonotic Diseases, 2008
Polymerase chain reaction analysis of Amblyomma americanum adults, nymphs, and larvae from Aberdeen Proving Ground, MD (APG), revealed a very high prevalence of a spotted fever group (SFG) rickettsia. Restriction fragment length polymorphism (RFLP) and sequence analysis identified "Rickettsia amblyommii." This organism is not yet described or well ...

Amblyomma americanum: a Potential Vector of Human Ehrlichiosis

The American Journal of Tropical Medicine and Hygiene, 1993
Polymerase chain reaction primers specific for Ehrlichia chaffeensis were used to amplify DNA from extracts of pooled ticks. Amplification was performed on extracts from 140 pools (1,579 total ticks) consisting of three tick genera collected from five states.

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.

Evidence for regurgitation by Amblyomma americanum

Veterinary Parasitology, 1988
Western blot analysis of Amblyomma americanum-derived midgut extracts using tick-resistant rabbit and guinea pig antisera demonstrated several unique polypeptides ranging from 7 to 355 kDa. These polypeptides were not observed in similar blots of salivary gland extracts or serum from the respective host animals.

Characterization of Glycine Rich Proteins in Amblyomma americanum

The FASEB Journal, 2016
Background The feeding habits of ticks require extended attachment of the tick on the host. This extended interaction with the host's immune system requires the tick to shield itself by modulating the host immune response with the use of multiple families of pharmacologically active compounds.
