In a new study from January 2015, published in the Journal of Clinical Microbiology and Infection,
199 anonymous patients from Belgium with known tick bite and symptoms of vector-borne disease were tested for Babesia using Indirect Fluorescent Antibody Test.
The serological screen detected positive reactivity in 9% (n = 18) against B. microti, 33.2% (n = 66) against B. divergens, and 39.7% (n = 79) Babesia sp. EU1, respectively.
