It compares allelic diversity based on approximately 500-bp internal gene fragments. Perhaps because of the limited numbers of epitopes presented to the immune system by parvovirus B19, the congenital immunodeficiency states associated with persistent infection may be clinically subtle, with susceptibility largely restricted to parvovirus, although multiple immune system defects are apparent when direct testing of T- and B-cell function is performed.

Cross-reactions have been reported between antibodies to Bartonella and Legionella micdadei and antibodies to C. Another possible mechanism of chlamydial persistence could be through a direct effect on the host cell, possibly through an effect on apoptosis, which is an important regulator of cell growth and tissue development. Sequence analysis has suggested that some of these changes may already be present in naturally occurring H5 viruses,117 and it will be important to continue monitoring isolates for sequences suggestive of successful human adaptation.
