[The evaluation of the mutagenic activity of pertussis vaccinal preparations]. / Otsenka mutagennoi aktivnosti kokliushnykh vaktsinal'nykh preparatov.

ABSTRACT

Two vaccine preparations obtained from Bordetella pertussis, whole-cell vaccine constituting one of the components of adsorbed DPT vaccine and acellular vaccine, were tested for mutagenicity. The doses of the preparations covered the range 1-100 ED50. Ames' test and the metaphase analysis of marrow cells of C57BL/6J mice were used. The acellular preparation was also tested on thymectomized mice, taking into consideration chromosomal aberrations in marrow metaphases. Whole-cell and acellular pertussis vaccines did not induce mutations in Salmonella typhimurium and chromosomal aberrations in mouse marrow cells.
