<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">in proven reservoir hosts (e.g., small mammals) it is no problem to detect Leishmania DNA by PCR in the circulating blood if these animals are
infected. However, one has to be very cautious with the selection of primers. For example, PCR methods based on primers targeting the small subunit rRNA gene or the 18S rRNA gene can yield positive results, but sequencing of the PCR products reveal the presence
of apathogenic Trypanosomes rather than Leishmania.<o:p></o:p></span></p>

</o:p></span></p>
<p><span style="font-family:"Calibri","sans-serif";color:black"><o:p> </o:p></span></p>
<p><span style="font-family:"Calibri","sans-serif";color:black">Thank you sincerely for your time. I am a tick-borne disease biologist by trade, so this is outside of my realm.

<p><span style="font-family:"Calibri","sans-serif";color:black;background:white">I am trying to confirm some preliminary data that suggests the
<em><span style="font-family:"Calibri","sans-serif"">Leishmania</span></em> spp. are circulating in limited geographic locales in southern Florida. Is it at all reasonable to expect to detect the DNA of the trypanosomatids in the blood of infected wildlife?
My suspicion is that this is completely improbable, as it appears that in order to detect DNA in enough quantity or quality for sequencing, you need cultured organisms. From sandflies it appears that it is possible to PCR amplify and sequence directly from
the vector, but never from the reservoir (or potential reservoir) host. Is this true? Any advice or insight would be greatly appreciated and I am tremendously naïve and this is clearly not my area of expertise</span><span style="font-family:"Calibri","sans-serif";color:black">.<o:p></o:p></span></p>
