| Abstract: | Several strains of mice were examined for antibody production after intranasal inoculation with a low virulence strain of mouse hepatitis virus (MHV), MHV-NuU. C57BL/6N mice were shown to be high responders in the production of complement fixing (CF) antibody as compared to C3H/HeN, BALB/c-AnN, DBA/2N mice. F1 hybrids B6C3 and BDF1 from C57BL/6N mice, showed CF antibody responses as high as C57BL/6N, suggesting that high responsiveness is genetically controlled. All these mouse strains were able to produce high titred neutralizing antibody to MHV. |
