Experiments conducted during all seasons have established that F. hetera, one of the mass species of fleas in Mountain Altai, can be infected both by the strain of selective virulence typical to this nidus and by the non-typical non-virulent mountain-altai strain of plague agent. The non-virulent strain does not form in fleas the block of proventriculus and within 1.5-2 months they become free from the microbe. At the infection with the typical strain of the altai subspecies rare transmissions of the agent to Pallas' pika can take place as well as its long preservation in fleas.
在所有季节进行的实验表明，阿尔泰山脉的主要跳蚤种类之一——异形蚤，既可以被该疫源地特有的选择性毒力菌株感染，也可以被鼠疫杆菌的非典型无毒阿尔泰山菌株感染。无毒菌株不会在跳蚤体内形成前胃阻塞，在1.5至2个月内它们会清除体内的微生物。当用阿尔泰亚种的典型菌株感染时，病原体也会罕见地传播给高原鼠兔，并且会在跳蚤体内长期留存。
