We investigated whether or not erythrovirus B19 is a candidate etiologic agent in such liver disease patients who had undergone liver transplantation. Methods Liver tissues from 47 patients consisted of 28 fulminant hepatitis and 19 biliary atresia were examined to detect B19 genes by PCR and further analyzed their genomic characterization. Results B19 DNA was detected by nested PCR in 10 of 28 cases 35.7 livers in the fulminant hepatitis group and 7 of 19 36.8 livers in the biliary atresia group respectively statistically not significant . Importantly among the 8 hepatic B19 DNA-positive patients who had paired samples of liver and serum the serum B19 genome was detectable in only one case. B19 mRNA was identified in all of 10
