VECTOR-BORNE DISEASES, SURVEILLANCE, PREVENTION Relative Encounter Frequencies and Prevalence of Selected Borrelia, Ehrlichia, and Anaplasma Infections in Amblyomma americanum and Ixodes scapularis (Acari: Ixodidae) Ticks from Central New Jersey
To evaluate their relative importance in tick-borne disease transmission in New Jersey, host-seeking Amblyomma americanum (L.) and Ixodes scapularis Say adults and nymphs were collected during spring activity periods in 2003 and 2004 to determine relative frequencies at which these ticks were encountered from an area known to be hyperendemic for Lyme disease. Although similar numbers of the two...
متن کاملPrevalence of Ehrlichia chaffeensis and Ehrlichia ewingii in ticks from Tennessee.
Human ehrlichiosis is the second most common tick-borne disease reported in Tennessee after Rocky Mountain spotted fever. Two closely related ehrlichiae, Ehrlichia chaffeensis and Ehrlichia ewingii, are both causative agents of human disease and are transmitted by Amblyomma americanum, the lone star tick. Prevalence rates and distribution patterns of these pathogens among ticks in Tennessee are...
متن کاملDevelopment of a mitochondrial 12S rDNA analysis for distinguishing Sciuridae species with potential to transmit Ehrlichia and Borrelia species to feeding Amblyomma americanum (Acari: Ixodidae).
Unique oligonucleotide probes were synthesized to distinguish among closely related vertebrate mitochondrial rDNA sequences present in residual bloodmeals in emergent Amblyomma americanum (L.) (Acari: Ixodidae) nymph life-stage ticks. Use of these probes enabled the identification of the Eastern gray squirrel as an important bloodmeal source in nymphs harboring Ehrlichia and Borrelia species. T...
متن کاملPrevalence and species of ticks on horses in central Oklahoma.
Ticks are common on horses, but there is a dearth of contemporary data on infestation prevalence, predominant species, and tick-borne disease agents important in this host. To determine the species of ticks most common on horses and the prevalence of equine exposure to and infection with tick-borne disease agents, ticks and blood samples were collected from 73 horses during May, June, and July ...
متن کاملInfection rates of Amblyomma americanum (Acari: Ixodidae) by Ehrlichia chaffeensis (Rickettsiales: Ehrlichieae) and prevalence of E. chaffeensis-reactive antibodies in white-tailed deer in southern Indiana, 1997.
To monitor the percentage and stability of Ehrlichia chaffeensis-infected ticks in southern Indiana over time, pools of Amblyomma americanum (L.) ticks were screened for infection in southern Indiana for a 2nd time. Nested polymerase chain reaction (with 6% DMSO included only in the 2nd reaction) was performed on 920 ticks in pools of 5 individuals from 9 sites (5 sites previously examined and ...
