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 ...

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.

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 ...

Effects of Photoperiod on Nymphal Diapause in Amblyomma americanum (Acari: Ixodidae)
Journal of Medical Entomology, 1988Oviposition, hatchability, and molting of larvae and nymphs were observed in Amblyomma americanum (L.) held in the laboratory under constant humidity and temperature, with variable photoperiods, during the off-host portion of the life cycle. Ticks were held at 0:24, 10:14, 12:12, or 14:10 (L:D) photoperiods during the period from egg to unfed nymph ...
