We tested the previously published hypothesis that spirochetes infecting Lone Star ticks (Amblyomma americanum) may comprise B. theileri by analyzing the 16S ribosomal DNAs (rDNAs) and flagellin genes of these spirochetes. B. theileri, the Amblyomma agent, and B. miyamotoi formed a natural group or clade distinct from but most closely related to that of the relapsing fever spirochetes. B. theileri and the Amblyomma agent were 97 and 98% similar at the nucleotide level within the analyzed portions of the 16S rDNA and the flagellin gene respectively, suggesting a recent divergence. The agent of bovine borreliosis might be explored as a surrogate antigen for the as-yet-uncultivatable Amblyomma agent in studies designed to explore the etiology of a Lyme disease-like infection associated with Lone Star ticks.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/11158095?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Armstrong, P M</style></author><author><style face="normal" font="default" size="100%">Rich, S M</style></author><author><style face="normal" font="default" size="100%">Smith, R D</style></author><author><style face="normal" font="default" size="100%">Hartl, D L</style></author><author><style face="normal" font="default" size="100%">Spielman, A</style></author><author><style face="normal" font="default" size="100%">Telford, S R</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A new Borrelia infecting Lone Star ticks.</style></title><secondary-title><style face="normal" font="default" size="100%">Lancet</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Lancet</style></alt-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Animals</style></keyword><keyword><style  face="normal" font="default" size="100%">Base Sequence</style></keyword><keyword><style  face="normal" font="default" size="100%">Borrelia</style></keyword><keyword><style  face="normal" font="default" size="100%">Borrelia Infections</style></keyword><keyword><style  face="normal" font="default" size="100%">Deer</style></keyword><keyword><style  face="normal" font="default" size="100%">Disease Vectors</style></keyword><keyword><style  face="normal" font="default" size="100%">DNA Primers</style></keyword><keyword><style  face="normal" font="default" size="100%">Maryland</style></keyword><keyword><style  face="normal" font="default" size="100%">Molecular Sequence Data</style></keyword><keyword><style  face="normal" font="default" size="100%">Ticks</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1996</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1996 Jan 6</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">347</style></volume><pages><style face="normal" font="default" size="100%">67-8</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><issue><style face="normal" font="default" size="100%">8993</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/8531586?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Rich, S M</style></author><author><style face="normal" font="default" size="100%">Caporale, D A</style></author><author><style face="normal" font="default" size="100%">Telford, S R</style></author><author><style face="normal" font="default" size="100%">Kocher, T D</style></author><author><style face="normal" font="default" size="100%">Hartl, D L</style></author><author><style face="normal" font="default" size="100%">Spielman, A</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Distribution of the Ixodes ricinus-like ticks of eastern North America.</style></title><secondary-title><style face="normal" font="default" size="100%">Proc Natl Acad Sci U S A</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Proc.

Two distinct lineages are evident. The southern clade includes ticks from the southeastern and middle-eastern regions of the United States. The range of the northern clade, which appears to have been restricted to the northeastern region until the mid-1900s, now extends throughout the northeastern and middle-eastern regions. These phyletic units correspond to northern and southern taxa that have previously been assigned specific status as Ixodes dammini and Ixodes scapularis, respectively. The expanding range of I. dammini appears to drive the present outbreaks of zoonotic disease in eastern North America that include Lyme disease and human babesiosis.</style></abstract><issue><style face="normal" font="default" size="100%">14</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/7603983?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Smith, R P</style></author><author><style face="normal" font="default" size="100%">Rand, P W</style></author><author><style face="normal" font="default" size="100%">Lacombe, E H</style></author><author><style face="normal" font="default" size="100%">Telford, S R</style></author><author><style face="normal" font="default" size="100%">Rich, S M</style></author><author><style face="normal" font="default" size="100%">Piesman, J</style></author><author><style face="normal" font="default" size="100%">Spielman, A</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Norway rats as reservoir hosts for Lyme disease spirochetes on Monhegan Island, Maine.</style></title><secondary-title><style face="normal" font="default" size="100%">J Infect Dis</style></secondary-title><alt-title><style face="normal" font="default" size="100%">J.

Prevalence of spirochetal infection was described for ticks removed from mammals, birds, and vegetation on Monhegan Island, Maine. Forty percent of adult I. dammini removed from vegetation were infected. Norway rats were heavily infested with ticks, and &gt; 60% of such ticks contained spirochetes. Other hosts were less frequently infested by ticks, and few such ticks were infected by spirochetes. The prevalence of antibody to B. burgdorferi was 23% in dogs and cats; 4% of island residents had Lyme disease. Thus, rats maintain Lyme disease spirochetes on Monhegan Island, and there may be transmission of this agent by I. dammini to island residents and their pets.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/8354910?dopt=Abstract</style></custom1></record></records></xml>
