Borrelia burgdorferi Promotes the
Establishment of Babesia microti in the
Northeastern United States
Abstract
Babesia microti and Borrelia burgdorferi, the respective causative agents of human
babesiosis and Lyme disease, are maintained in their enzootic cycles by the
blacklegged tick (Ixodes scapularis) and use the white-footed mouse (Peromyscus
leucopus) as primary reservoir host. The geographic range of both pathogens has
expanded in the United States, but the spread of babesiosis has lagged behind that
of Lyme disease.
From Dr Horowitz on Facebook:
This article on Lyme disease and Babesiosis was just published in PLoS ONE. Dr Peter Krause and a team of researchers demonstrated in the laboratory that the frequency of Babesia microti infected ticks is higher when fed on white footed mice that are co-infected with both Lyme and Babesia, than on mice just infected with B. microti alone.This article follows recent scientific observations published by Dr Rick Ostfeld earlier this year in PLoS ONE, that the rate of co-infectio...n with Babesiosis and Lyme is higher than expected in small mammals (http://www.plosone.org/…/info%3Adoi%2F10.1371%2Fjournal.pon…). These two articles confirm what I have been seeing in clinical practice for almost two decades: Babesiosis is rising, and is a common co-infection seen in my chronically ill patients. Once Babesia is adequately treated, many patients who have failed classical Lyme treatments will clinically improve.
