Methods A total of 950 blood samples were collected from voluntary blood donors in Jiangsu Provincial Blood Center from February to May, 2017, and detected by double antigen sandwich ELISA targeting peptides derived from B. microti-secreted antigen 1 (BmSA1). The positive samples were confirmed by microscopy and nested?PCR to determine parasitemia. The prevalence of anti?BmSA1 was analyzed between/among different genders, ages and occupations of the blood donors. Results Of the 950 blood screened samples, 5 were positive for anti?BmSA1, and the sero?prevalence of Babesia infection was 0.53%. The 5 samples were all negative by microscopy and nested?PCR. There were no gender? ([χ2] = 0.01, P = 0.92) or age?specific differences ([χ2] = 0.11, P = 0.95) in the sero?prevalence of Babesia infection; however, there was an occupation?specific difference detected in the sero?prevalence of Babesia infection ([χ2] = 11.93,P < 0.05). Conclusion Babesia infection is detected in voluntary blood donors in Jiangsu region, which should be paid much attention. %U https://www.zgxfzz.com/EN/abstract/article_10979.shtml
