title: Susceptibility of trout kidney macrophages to viral hemorrhagic septicemia virus.
abstract: Viral hemorrhagic septicemia virus (VHSV) lysed the macrophages from rainbow trout kidney cultures either isolated by plastic adherence or stimulated with purified glycoprotein G from VHSV. The trout macrophages supported the replication of VHSV as tested by cell culture and by sandwich ELISA of the supernatants from infected cultures. VHSV-infected macrophages showed a decrease in both acridine-orange fluorescence and average size. Immunofluorescence studies with flow cytometry showed positive membrane staining with monoclonal antibodies (MAbs) anti-N and anti-G VHSV. These findings open the possibility of using trout macrophages as presenting cells to study the possible existence of helper or cytotoxic epitopes relevant to the protection of trout against VHSV.
