Characterization of Glycine Rich Proteins in Amblyomma americanum

The FASEB Journal, 2016
Background 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.

Antigens of Amblyomma americanum Ticks Recognized by Repeatedly Infested Sheep

The Journal of Parasitology, 1991
Sera 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 ...

Biosynthesis of salivary prostaglandins in the lone star tick, Amblyomma americanum

Insect Biochemistry and Molecular Biology, 1995
Dopamine-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, 1991
Three 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.

SUSCEPTIBILITY OF AMBLYOMMA AMERICANUM TO NATURAL AND EXPERIMENTAL INFECTIONS WITH THEILERIA CERVI

Journal of Wildlife Diseases, 1988
One 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.
