Immunofluorescent antibody response to lactic dehydrogenase virus in different strains of mice.

The development of antibody against lactic dehydrogenase virus in five strains of mice (NZB x NZWF1, BALB/c, C.B-17, ICR and C.B-17 scid or SCID mice) was examined by indirect immunofluorescence (IIF) of infected liver sections. IIF antibody appeared 1 to 3 weeks and rose progressively 2 to 4 weeks after infection in four strains of mice (NZB x NZWF1, BALB/c, C.B-17 and ICR mice). SCID mice did not develop antibody. These results suggest that IIF may be applicable for detecting LDV infection in many other ordinary strains of mice.
