Anti-phosphocholine (PC) antibody mediated protection against many strains of Streptococcus pneumoniae, and hybridoma anti-PC antibodies protected mice from fatal infections with types 1 and 3 S. pneumoniae. Live types 1, 3, 5, 6A, and 19F S. pneumoniae had similar amounts of surface PC accessible to antibody. Furthermore, mice expressing the X-linked immunodeficiency (xid) of the CBA/N strain were found to be more susceptible to infection with S. pneumoniae of types 3, 6A, and 19F than were immunologically normal mice. The only exception to these results was with the type 5 strain, which was highly virulent for both xid and normal mice. In addition, we were unable to protect mice against infection with the type 5 strain by using anti-PC antibody.
抗磷酸胆碱(PC)抗体介导对多种肺炎链球菌菌株的保护作用,杂交瘤抗PC抗体可保护小鼠免受1型和3型肺炎链球菌的致命感染。活的1型、3型、5型、6A 型和19F型肺炎链球菌表面可被抗体识别的PC量相似。此外,发现表达CBA/N品系X连锁免疫缺陷(xid)的小鼠比免疫正常的小鼠更易感染3型、6A 型和19F型肺炎链球菌。这些结果的唯一例外是5型菌株,它对xid小鼠和正常小鼠都具有高毒性。此外,我们无法用抗PC抗体保护小鼠免受5型菌株的感染。
