ABSTRACT
Objective To detect human parvovirus B19(B19V)DNA in source plasma pools and coagulation factor products and determine its prevalence and the level of contamination .Methods A pair of primers and a probe selected from the highly conserved sequences encoding the non-structural protein(NS1)of B19 were designed and synthesized.With the primer-probe combination ,source plasma pools and four types of coagulation factor products were determined for B 19V DNA by TaqMan real-time quantitative PCR.Results One-hundred and sixteen from 195 (59.49%) source plasma pools contained B19 DNA and concentrations up to 1.35 ×1010 copies/ml were measured.High frequencies of contamination were detected in factor Ⅷ (29 of 31; 93.55%), thrombin (10 of 10; 100%), fibrinogen (6 of 7; 85.71%) and prothrombin complex (8 of 9;88.89%).Conclusion These data show that B19V is a common contaminator in Chinese source plasma pools and coagulation factor products .Thus,B19V screening in Chinese source plasma seems desirable and significant for the safety of plasma derivatives in China .
