In this study, the course of infection was monitored by detectable B19V-DNA and HAV-RNAin serum samples in association with drops in RBC parameter, particularlyreticulocytopenia, mild to moderate anaemia, as well as detection of a nuclear inclusionin basophilic pro-erythroblast and B19V Ag detection in liver samples during the 59thday of investigation. Here, RENBP is linked to anemia (phenotype).
