Last year, Canadian public health officials and legislators made great strides in recognizing the existence and threat within their country of Borrelia burgdorferi (Bb), the tick-borne organism which causes Lyme disease. Now, there’s evidence that Babesia, a parasite which infects red blood cells and is transmitted primarily through the bite of black-legged ticks, may have reached Canada, as well.
Babesia has become the second most common pathogen tick-borne disease in a recent Dutchess County, NY, USA trial. Nearly 14% of questing nymphal ticks were infected with B. microti, the cause of Babesia. Over 29% of the same ticks were infected with B. burgdorferi, the cause of Lyme disease. Only 8.5% of these ticks were infected with HGE, the cause of Anaplasmosis.
