Infection of rabbits with bovine immunodeficiency-like virus.
New Zealand white rabbits, which had been prepared for inoculation by intraperitoneal treatment with thioglycollate, were inoculated intraperitoneally with bovine immunodeficiency-like virus (BIV). Infected materials from various sources were used including cultured cells and culture fluids, peripheral blood leukocytes from infected cattle and spleen tissue from previously infected rabbits. Virus isolations and serological responses detected by western blotting provided clear evidence that infections had been established in inoculated rabbits and that the spleen was an important site of BIV infectivity. These results indicate that rabbits may be a useful species when testing for BIV infectivity in materials too toxic or highly contaminated to be inoculated directly into cell cultures. Furthermore, rabbits may also be useful in testing effects of coinfections with other bovine viruses on progression of BIV infection and for the initial evaluation of therapeutic regimens designed to suppress or eliminate BIV infections.
