Echinococcus granulosus protoscolex (PSC) infection of BALB/c mice led, after 4 days, to raised numbers of cells forming plaques with trinitrophenyl-treated sheep red cells and bromelain-treated mouse red cells. The findings were similar in athymic and euthymic CBA mice. Activation of B cells was accompanied by secretion of immunoglobulin, as indicated by the reverse plaque technique. In addition, co-culture of PSC with the 7OZ/3 pre-B-cell led to the induction of differentiation, resulting in the expression of surface immunoglobulin (Ig). It is concluded that E. granulosus is a polyclonal activator of B cells inducing both transformation and differentiation, and that the effect is thymus-independent.
