I am wondering if Columbia University Research Center uses xenodiagnosis for detection of infectious diseases?

This is an interesting question. Xenodiagnosis in this case refers to allowing an uninfected tick to feed on an individual with suspected infection to see whether the tick is able to suck up spirochetes when the spirochetes might not have been detectable otherwise. As strange as this concept appears, it has been used successfully recently by Dr. Steven Barthold at UC Davis. After being unable to identify persistent infection in a treated infected mouse using the standard PCR and culture techniques, he was then able to identify the spirochetes in these mice after treatment using the xenodiagnosis method. We at Columbia are not using this method on humans. This is a very intriguing scientific question that should be studied in humans.
