Babesiosis is one of the most frequently observed co-infections in my Lyme patients that contributes to persistent illness.


From Dr Horowitz

Babesiosis is one of the most frequently observed co-infections in my Lyme patients that contributes to persistent illness. There are many species of Babesia, and Babesia microti and Babesia WA-1/duncani are the most common species in the US, with Babesia divergens and Babesia venatorum (EU-1) being commonly seen in Europe. Other species are emerging in the US like Babesia odocoilei
(Increased diversity of zoonotic pathogens and Borrelia burgdorferi strains in established versus incipient Ixodes scapularis populations across the Midwestern United States. Hamera, S. et al. DOI: 10.1016/j.meegid.2014.06.003). In this article published in Cellular Microbiology, the authors describe details of Babesia's biology that may help us to control parasite populations. Any Lyme patient with ongoing unexplained malaria-like symptoms such as fevers, day and night sweats, chills, an unexplained cough and "air hunger/shortness of breath" may have Babesiosis. A Babesia panel, checking titers (IFA for B.microti and B. duncani), PCR's and RNA testing (FISH, IgeneX laboratory) may help identify Babesiosis. A differential diagnostic map to identify the multiple causes of fevers and sweats can be found on page 68 of Why Can't I Get Better?".
