Figure

Immunoglobulin (Ig) G and IgM immunoblots of 3 mothers for infection with parvovirus 4 (PARV4) (left) or parvovirus B19 (B19V) (right). Case-patient A was co-infected with PARV4 and B19V; case-patient B was the only mother who did not have IgM against PARV4; case-patient E had weak IgM against PARV4 viral protein (VP) 3 and IgM against B19V VP2N, which could not be seen after scanning. Molecular weights are ≈60 kDa for PARV4 VP2, 51 kDa for PARV4 VP3, 51 kDa for B19V VP2N, and 41 kDa for B19V VP
