  <dc:description>&lt;p&gt;The lone star tick, &lt;i&gt;Amblyomma americanum&lt;/i&gt; (L.), has increased in abundance in several regions of the northeastern United States, including areas of Long Island, NY. Adult and nymphal stage &lt;i&gt;A. americanum&lt;/i&gt; collected from several sites on Long Island were evaluated for infection with &lt;i&gt;Ehrlichia chaffeensis&lt;/i&gt;, the causative agent of human monocytic ehrlichiosis (HME), by using a nested polymerase chain reaction assay. Fifty-nine (12.5%) of ,17.3 adults and eight of 11.3 pools of five nymphs each (estimated minimum prevalence of infection 1.4%) contained DNA of &lt;i&gt;E. chaffeensis&lt;/i&gt;. These data, coupled with the documented expansion of lone star tick populations in the northeastern United States, confirm that &lt;i&gt;E. chaffeensis&lt;/i&gt; is endemic to many areas of Long Island and that HME should be considered among the differential diagnoses of the many distinct tick-borne diseases that occur in this region.&lt;/p&gt;</dc:description>
