Using a bactericidal assay for the presence of antibody it was found that 1-day-old chicks had little natural antibody against . However, in contrast adult hens possessed relatively higher levels. The titre of antibody could not be increased in chicks by prior immunization at the time of hatching. These results are in conflict with those recently reported by Solomon (1968a).
通过杀菌试验检测抗体的存在,发现1日龄雏鸡几乎没有针对……的天然抗体。然而,相比之下,成年母鸡的抗体水平相对较高。在雏鸡孵化时预先免疫并不能提高其抗体滴度。这些结果与所罗门(1968a)最近报道的结果相矛盾。
