Genetic analysis has demonstrated distinct variation in the rDNA internal transcribed spacer 2 sequence in 2 populations of Amblyomma americanum (colony and wild). The ability to transmit the protozoan parasite Theileria cervi was quantitatively assessed of for each of these 2 genetically characterized populations of A. americanum. Feeding success of individuals of both populations of A. americanum was compared using the percentage tick yield and engorgement weight of acquisition-fed nymphs. Vector competency of individuals within both populations of A. americanum was measured using the prevalence, abundance, and intensity of infection as defined by the number of T. cervi–infected acini. Significantly higher proportions of acquisition-fed nymphs of colony and wild A. americanum were recovered, depending on which donor deer they infested. A significant correlation was not detected between percentage tick yield and parasitemia of donor deer. Wild A. americanum nymphs had significantly higher engorg... |
