Borrelia burgdorferi in small mammal reservoirs in Kentucky, a traditionally non-endemic state for Lyme disease

The incidence of tick-borne zoonoses such as Lyme disease has steadily increased in the southeastern United States. Southeastern states accounted for 1500 of over 28,000 confirmed cases of Lyme disease reported in the United States during 2015. Borrelia burgdorferi, the etiologic agent of Lyme disease, is maintained in small mammal reservoirs and vectored to new hosts by ixodid ticks.
This study examined ecological relationships of the B. burgdorferi/vector/reservoir system in order to understand the dynamics of Lyme disease risk in Kentucky. Small mammals were captured using live traps from November 2014 to October 2015. Ticks were removed and blood and tissue collected from small mammals were screened for B. burgdorferi DNA by PCR with primers specific to the OspA gene.
Prevalence of B. burgdorferi (21.8%) in Kentucky small mammals was comparable to the lowest recorded prevalence in regions where Lyme disease is endemic. Moreover, infestation of small mammals by Ixodes scapularis, the primary vector of B. burgdorferi, was rare, while Dermacentor variabilis comprised the majority of ticks collected.
These findings provide ecological insight into the relative paucity of Lyme disease in Kentucky.
The conclusion of this study is all wrong. Bb was found Kentucky mammals. That in itself is important. Also, the fact the preponderance of ticks were dermacentor variabilis (wood tick or American dog tick) which supposedly has not been proven to be a competent vector of Bb as supposedly it doesn’t efficiently pass Bb from inside the tick to humans or other hosts), it does transmit Tularemia and Rocky Mountain Spotted Fever.
BTW: these transmission studies given as references for this fact were done from 1997-2006. It’s now 2018. http://labs.russell.wisc.edu/wisconsin-ticks/wisconsin-ticks/dermacentor-variabilis/ Notice it states, “It doesn’t efficiently pass Bb.” What if it passes it inefficiently? It still passes!
Regardless of whether the wood tick can transmit Bb or not, they do transmit pathogens. The fact that nearly 22% of small Kentucky mammals have Bb due to the black legged deer tick and most of the ticks they picked up were wood ticks, those deer ticks were particularly infected.
Hear ye, hear ye, the South has Lyme.

“We don’t have Lyme Disease in Arkansas, we have the ticks that transmit Lyme Disease but we don’t have any recorded cases of Lyme Disease.”
https://madisonarealymesupportgroup.com/2017/03/02/hold-the-press-arkansas-has-lyme/ A news report emphasizing the CDC’s belief Arkansas is a “low incident” state in regards to Lyme Disease, is countered by the Arkansas Lyme Foundation that claims at least 150 cases, and they just started counting. http://www.thv11.com/news/local/arkansas-lyme-foundation-claims-over-150-lyme-disease-cases-in-state/414489522 (Video here)

“That’s a spider bite,” a local pediatrician told her. “We don’t have Lyme in Oklahoma.”
The doctor was wrong. Had my friend taken his advice, her daughter would not have been diagnosed in a timely fashion and she would likely have developed symptoms over the next few months or years. She probably would have become severely debilitated, and the infections might have crossed the blood-brain barrier and become chronic.
Get the picture yet? Lyme/MSIDS is everywhere.
Quit saying it’s rare!
