Amblyomma americanum: a Potential Vector of Human Ehrlichiosis
The American Journal of Tropical Medicine and Hygiene, 1993Polymerase 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.

Transmission of Cytauxzoon felis to a domestic cat by Amblyomma americanum
Veterinary Parasitology, 2009Cytauxzoon felis was transmitted to a domestic cat by Amblyomma americanum. The infection was produced by the bite of A. americanum adults that were acquisition fed as nymphs on a domestic cat that naturally survived infection of C. felis. Fever, inappetence, depression, and lethargy were first noted 11 days post-infestation (dpi). Pale mucus membranes,

Evidence for regurgitation by Amblyomma americanum
Veterinary Parasitology, 1988Western 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.

Seasonal Activity and Relative Abundance of Amblyomma americanum in Mississippi
Journal of Medical Entomology, 1996Ecological investigations of the lone star tick, Amblyomma americanum (L.), were conducted in 3 adjacent 60-m2 plots, located in Noxubee National Wildlife Refuge, Noxubee County, Mississippi. Ticks were collected weekly from July 1992 to July 1993 by flagging randomly selected lanes.

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.

The molecular basis of the Amblyomma americanum tick attachment phase
Experimental and Applied Acarology, 2007Towards discovery of molecular signaling cascades that trigger and/or facilitate the tick attachment and formation of its feeding lesion, suppressive subtractive hybridization, high throughput sequencing and validation of differential expression by cDNA dot blot hybridization were performed on Amblyomma americanum ticks that had attained appetence and ...

Range expansions are a potential outcome of changes in habitat suitability, which commonly result as a consequence of climate change. Hypotheses on such changes in the geographic distribution of a certain species can be evaluated using population genetic

Rickettsia amblyommiiInfectingAmblyomma americanumLarvae
Vector-Borne and Zoonotic Diseases, 2008Polymerase 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 ...
