Abstract

Because many strains of mouse hepatitis virus (MHV) infect laboratory mice, no effective vaccine has yet been developed. An alternative approach to control MHV disease is the use of a host cell receptor-targeted ligand. To address the potential usefulness of this approach, a monoclonal antibody directed against the host cell receptor for the coronavirus MHV-A59 was administered to infant mice that were then challenged oronasally with 104 intracerebral infant mouse median lethal doses of MHV-A59. Antibody treatment of virus-challenged mice resulted in lower proportions of mice with MHV-A59 in target organs and markedly reduced viral titers in these organs compared with mock-treated infected mice. Some antibody-treated infected mice survived for 7 days after viral challenge, whereas no mock-treated, infected mice survived beyond day 3 after viral inoculation. These results support a receptor-targeted approach to intervention in coronavirus disease.
