Four Salmonella serotypes which had been subjected to either 15 or 20 cycles of irradiation and subculture were examined for possible changes induced by the treatment. With three serotypes virulence remained unchanged, and with one serotype a reduction had occurred. A few minor changes in the biochemical characteristics occurred in some instances, but with all cultures the serological property was affected to some extent. Lag times and growth rates of the treated cultures were not altered, but the maximal viable population was usually less than that for untreated cultures.
对经过15或20轮辐照和传代培养的四种沙门氏菌血清型进行检测，以确定该处理是否会引发可能的变化。三种血清型的毒力保持不变，一种血清型的毒力有所降低。在某些情况下，生化特性出现了一些细微变化，但所有培养物的血清学特性均受到了一定程度的影响。处理后培养物的延迟期和生长速率没有改变，但最大活菌数通常低于未处理的培养物。
