Borreliacidal activity of saliva of the tick Amblyomma americanum [PDF]

Medical and Veterinary Entomology, 2005
Amblyomma americanum (Linneaus) (Acari: Ixodidae), an important tick vector of human and animal disease, is not a competent vector of the bacterial agent of Lyme disease, Borrelia burgdorferi, although its range overlaps the geographical distribution of ...

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.

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.

Seasonal Activity and Relative Abundance of Amblyomma americanum in Mississippi

Journal of Medical Entomology, 1996
Ecological 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.

Transmission of Cytauxzoon felis to a domestic cat by Amblyomma americanum

Veterinary Parasitology, 2009
Cytauxzoon 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,

The molecular basis of the Amblyomma americanum tick attachment phase

Experimental and Applied Acarology, 2007
Towards 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 ...

Genome size and organization in the ixodid tick Amblyomma americanum (L.)

Insect Molecular Biology, 1994
Abstract We used DNA reassociation kinetics to determine genome size and organization in the ixodid tick Amblyomma americanum. We calculated the genome size of A.

Rickettsia amblyommii Infecting Amblyomma americanum Larvae

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 ...
