The antiphosphocholine (PC) antibody in normal mouse sera (NMS) provides protection
against intravenous infection with encapsulated strain WU2 of type 3 Streptococcus
pneumoniae. Mice unable to make anti-PC antibody, as a result of suppression with anti-T-
15 idiotype or inheritance of the xid gene of CAB/N mice, are highly susceptible to infection
with strain WU2. Mice inheriting the xid gene can be protected with NMS from
immunologically normal mice or with IgM hybridoma anti-PC antibody. The protective effect …
The antiphosphocholine (PC) antibody in normal mouse sera (NMS) provides protection against intravenous infection with encapsulated strain WU2 of type 3 Streptococcus pneumoniae. Mice unable to make anti-PC antibody, as a result of suppression with anti-T-15 idiotype or inheritance of the xid gene of CAB/N mice, are highly susceptible to infection with strain WU2. Mice inheriting the xid gene can be protected with NMS from immunologically normal mice or with IgM hybridoma anti-PC antibody. The protective effect of NMS can be removed with PC-containing immunoabsorbents.
