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.

SUSCEPTIBILITY OF AMBLYOMMA AMERICANUM TO NATURAL AND EXPERIMENTAL INFECTIONS WITH THEILERIA CERVI
Journal of Wildlife Diseases, 1988One hundred fifty Amblyomma americanum were examined between March and September 1986 from Cookson Hills Wildlife Refuge in eastern Oklahoma (USA). Of these ticks, 11% (17 of 150) were infected with Theileria cervi. Field-collected nymphal ticks had an 8% (3 of 37) prevalence of infection averaging 1.0 infected acini/nymph.

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.

Characterization of Glycine Rich Proteins in Amblyomma americanum
The FASEB Journal, 2016Background 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.

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 ...

Rickettsia amblyommii Infecting Amblyomma americanum Larvae
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 ...

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 ...
