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 ...

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

Journal of medical entomology, 2020
We compared the ability of product formulations representing a synthetic pyrethroid acaricide (Talstar P Professional Insecticide), a natural product-based acaricide (Essentria IC3), and an entomopathogenic fungal acaricide (Met52 EC Bioinsecticide) to ...

Biosynthesis of salivary prostaglandins in the lone star tick, Amblyomma americanum
Insect Biochemistry and Molecular Biology, 1995Dopamine-induced saliva from ticks fed [3H]arachidonic acid contained the radiolabelled prostaglandins E2, F2 alpha, D2, and B2, the latter probably derived from PGE2 owing to the alkalinity of tick saliva. Prostaglandin synthetase (PGS) activity in the salivary gland homogenate from the lone star tick, Amblyomma americanum, could not be detected by ...

Manifestations of Immunity in Sheep Repeatedly Infested with Amblyomma americanum Ticks
The Journal of Parasitology, 1991Three sheep were infested 4 times with 100 Amblyomma americanum tick pairs and kept indoors until the natural termination of the infestations. Characteristics of the tick populations that show efficiency of feeding, fertility, and offspring development, and ELISA antibodies to tick salivary gland extracts were studied at each infestation.

Antigens of Amblyomma americanum Ticks Recognized by Repeatedly Infested Sheep
The Journal of Parasitology, 1991Sera were taken from 3 sheep that had been infested 5 times with Amblyomma americanum and that exhibited manifestations of humoral depression to homologous antigens and anti-tick resistance. Proteins extracted from the intestine or salivary glands of unfed ticks or salivary glands from partially (3-day) fed ticks were analyzed by polyacrylamide gel ...

Genome size and organization in the ixodid tick Amblyomma americanum (L.)
Insect Molecular Biology, 1994AbstractWe used DNA reassociation kinetics to determine genome size and organization in the ixodid tick Amblyomma americanum. We calculated the genome size of A. americanum to be approximately 1.08 pg or 1.04 × 109 base pairs and to consist of 35.8% unique DNA, 4.2% foldback sequences, 17.9% highly repetitive sequences, and 42.1% moderately repetitive ...
