Abstract

In an attempt to generate large numbers of mice resistant to Plasmodium berghei and Babesia rodhaini to be used as donors of antibody-secreting cells for hybridoma production, various methods of inducing resistance to repeated challenge with infected blood cells have been explored. Although results of independent experiments varied markedly, prior injection of CBA/M mice with BCG, and prior infection of BALB/c mice with Plasmodium yoelii, were found to be manipulations capable of inducing resistance to P. berghei. A single dose of serum, harvested from resistant mice challenged several times with P. berghei, could transfer resistance against P. berghei to a proportion of naive CBA/H recipients. Although resistance to multiple B. rodhaini challenge could be induced in mice, in no situation was a host protective effect of a single high dose of serum demonstrated in naive recipients.
