Abstract

Lactic dehydrogenase virus (LDV) associated with transplantable line Ib lymphocytic leukemia in C58/Wm mice, K36 lymphocytic leukemia in AKR/J mice, and the Gardner lymphosarcoma in C3H/HeJ mice elicited a fatal neuroparalytic disease when injected ip into 7- to 9-month-old X-irradiated indicator C58 mice. LDV associated with the WEHI-3B line of transplantable myelomonocytic leukemia or the Harding-Passey transplantable myeloma in BALB/c mice failed to elicit the disease. Recipients of such tumor extracts were immune to rechallenge by line Ib-associated LDV. Tumor lines free of LDV failed to elicit the disease or immunize recipient mice to line Ib LDV challenge. The Plagemann (P-LDV), Riley (R-LDV), and Notkins (N-LDV) strains of LDV were less neuropathogenic than the line Ib-derived strain (Ib-LDV). Indicator C58 mice that survived infection by the P-LDV, R-LDV, and N-LDV strains were immune to rechallenge by Ib-LDV. Antiserum prepared in young C58 mice to Ib-LDV or R-LDV protected indicator C58 mice from Ib-LDV challenge. These results show that a common viral contaminant of transplantable tumors and virus stocks that ordinarily is not pathogenic elicits a fatal neurologic disease in genetically susceptible, immunosuppressed, C58 mice.
