Vesicular Eruption Secondary to Bites by Larval Amblyomma americanum
Cutis, 2022Tick-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.

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.

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, 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.

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 ...

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,
