A study of nonspecific stimulation of the avian immune system with Corynebacterium parvum and specific stimulation with Marek's tumor cell vaccines revealed that nonspecifically stimulated outbred White Leghorn-type cockerels had higher incidences of tumors than did controls. A study of tumor cell cytotoxicity of sera from Marek's disease virus exposed birds indicated that humoral factors may play some role in tumor resistance.
一项关于用短小棒状杆菌对禽类免疫系统进行非特异性刺激以及用马立克氏肿瘤细胞疫苗进行特异性刺激的研究表明，经非特异性刺激的远交白来航型小公鸡比对照组有更高的肿瘤发生率。一项关于感染马立克氏病病毒的禽类血清的肿瘤细胞细胞毒性研究表明，体液因子可能在肿瘤抗性中发挥一定作用。
