We isolated a novel infectious murine leukemia virus (HoMuLV) from the wild mouse Mus hortulanus. HoMuLV has an ecotropic virus host range, but the viral DNA fails to hybridize to viral envelope segments specific for the known inbred and wild mouse ecotropic as well as nonecotropic MuLVs. Despite this difference in its env gene, HoMuLV appears to use the same ecotropic cell-surface receptor since it infects only hamster and mouse somatic cell hybrids which contain the Rec-1 ecotropic virus receptor on chromosome 5. Furthermore, HoMuLV does not infect mice carrying the Fv-4r allele which is thought to prevent ecotropic virus infection through an interference mechanism. HoMuLV is NB-tropic and, unlike other infectious MuLVs, does not grow in cells derived from the wild mouse species. M. dunni. Five to ten months after neonatal inoculation with HoMuLV, 72% of female NIH Swiss mice (8/11) contracted lymphoma or erythroid leukemia, but 33% of the inoculated males (5/15) developed erythroid or myelogenous leukemia within 8-16 months. These data suggest that NIH Swiss males and females differ in their susceptibility to HoMuLV-induced disease. Furthermore, NIH Swiss mice were found to be more susceptible to HoMuLV-induced disease than NFS/N mice. Tumors contained infectious MCF virus, which is consistent with the hypothesis that MCF virus may mediate tumorigenesis by HoMuLV.
