Arrieta, M. C., Leskiw, B. K., Kaufman, W. R.
Abstract: Eggs of the tick Amblyomma hebraeum Koch (Acari: Ixodidae) inhibited the growth of Escherichia coli and Serratia marcescens (Gram-negative bacteria) in solid culture, but not the growth of Staphylococcus epidermidis, and only marginally the growth of Bacillus subtilis (Gram-positive...

Yu, Z., Liu, J., Kaufman, W. R., Thomson, E. L. S., Dennis, J. J., Jacobs, R. L.
Abstract: Untreated eggs of the tick Amblyomma hebraeum Koch (Acari: Ixodidae) exhibited antimicrobial activity (AMA) against Gram-negative but not Gram-positive bacteria; eggs denuded of wax by solvent extraction showed no AMA. The unfractionated egg wax extract, however, showed AMA against...

Cuticular plasticization in the tick, Amblyomma hebraeum (Acari: Ixodidae): possible roles of monoamines and cuticular pH

Reynolds, S. E., Flynn, P. C., Kaufman, W. R.
Abstract: The degree of plasticization of the alloscutal cuticle of a 'hard' (ixodid) tick, Amblyomma hebraeum, and a 'soft' (argasid) tick, Ornithodoros moubata, was assessed throughout the blood-feeding period. Cuticle viscosity was calculated from rate of creep of cuticle under constant load...

Genetic diversity and host specificity in the winter tick - Dermacentor albipictus (Acari: Ixodidae)
DownloadFall 2012
Dermacentor albipictus (Packard) is an obligate, hematophagous ectoparasite commonly found on large ungulates in North America. At high infestation levels, the winter tick is known to cause severe pathology and may transmit diseases to its hosts. Knowledge of the genetic diversity in this...
