Expression of the mammary tumor virus (MTV) antigen in the milk from inbred mouse strains maintained in Japanese laboratories was investigated by means of the immunodiffusion test (ID) and the results were compared with the incidence of mammary tumors in breeding females of identical strains. Japanese strains tested were classified into two groups. The DD/Tbr, DDD and KF strains were derived from "dd" stock mice, and they showed equally high incidences of MTV antigen expression in the milk, though each strain developed mammary tumors with different incidences; 71%, 14% and 22%, respectively. Other strains originated from Swiss albino mice. The incidence of MTV antigen expression in the milk of SHN and SLN strains was the same as that of mammary tumors at an early age.
通过免疫扩散试验（ID）研究了日本实验室饲养的近交系小鼠乳汁中乳腺肿瘤病毒（MTV）抗原的表达情况，并将结果与相同品系繁殖雌鼠的乳腺肿瘤发病率进行了比较。所检测的日本品系分为两组。DD/Tbr、DDD和KF品系源自“dd”原种小鼠，它们乳汁中MTV抗原表达的发生率同样很高，尽管各品系乳腺肿瘤的发生率不同，分别为71%、14%和22%。其他品系源自瑞士白化小鼠。SHN和SLN品系乳汁中MTV抗原表达的发生率与幼年时乳腺肿瘤的发生率相同。
