title: [Protein expression of Yersinia pestis during changes due to long-term cultivation in vivo].
abstract: The electrophoretic study of Yersinia pestis proteins made possible to find the significant modification of Yersinia pestis polypeptide specters when the bacteria were cultivated in semi-penetrable cells implanted into the guinea pigs peritoneum. The proteinogramms of the isolates from the implanted cells lacked the stained bands characteristic of Yersinia pestis cells grown in vitro and contained the new polypeptides absent from the bacteria grown on the Hottinger agar plates. The difference was found at the late stage of bacteria incubation in implanted cells and had the predominantly reversible characteristics. The protein of Yersinia pestis being changed in vivo is proposed to be the species specific fraction I.
