Babesiosis is an emerging tick-borne disease mainly caused Babesia microti, a protozoan that infects erythrocytes. Microscopic examination of blood smears is the current gold standard for detection of Babesia infection, but this diagnostic test has several limitations. We developed and assessed the clinical utilization of a multiplex real-time PCR assay(More)
Using a real-time quantitative PCR (qPCR), we determined the number of DNA copies/mL of blood of a Babesia microti gene in infected patients. Thirty-six patients (whose median age was 62.5years and 75.0% were male) with at least 1 qPCR-positive blood sample were included in this analysis, including 16 with serial blood samples. Based on testing of serial(More)
OBJECTIVES Anemia and thrombocytopenia are expected hematologic abnormalities in patients with acute babesiosis, whereas neutropenia (defined as an absolute neutrophil count of ≤1,800 neutrophils/μL for adults and <1,200 neutrophils/μL for infants) is not usually considered a feature of this infection. We studied the frequency with which neutropenia occurs(More)
