Abstract
In order to assess whether the spleen is the major site of replication of lactate dehydrogenase-elevating virus (LDV) in mice during the acute phase of infection, LDV replication in the spleen was measured by electron microscopy and fluorescent antibody staining of tissue sections and northern hybridization of total spleen RNA with an LDV-specific cDNA probe, and the effect of splenectomy on LDV replication was determined. LDV RNA and antigens and infected cells, presumably macrophages, were present in the spleen in high concentrations 18–25 h post infection, but then rapidly disappeared to undetectable levels during the next 1–2 days. Thus, LDV clearly replicates in the spleen during the initial phase of infection, but LDV replication in the spleen is transient due to the cytocidal nature of LDV replication and destruction of all permissive macrophages in the spleen. Furthermore, spleen macrophages do not seem to represent the major source of LDV released into the circulation, since LDV viremia as well as anti-LDV antibody production were the same in splenectomized and control animals for at least 28 days postinfection.
