Toxigence of anthrax vaccine strains
The article presents the results of the studying of anthrax strains and Bacillus anthracis-like strains on the formation of toxins. We found that anthrax vaccine strains actively produce exotoxins to the culture fluid. The amount of specific protein is different under the same incubation conditions and depends on the individual characteristics of the ...

Candidate cytomegalovirus strain for human vaccination [PDF]
A strain of human cytomegalovirus called Towne was isolated in WI-38 human fibrolast cell cultures from the urine of an infected infant. It was then passaged 125 times in WI-38, including three clonings, and a pool was prepared in the same cell substrate for use as a potential live attenuated vaccine.

Genetic Characterization of Measles Vaccine Strains [PDF]
AbstractThe complete genomic sequences of 9 measles vaccine strains were compared with the sequence of the Edmonston wild-type virus. AIK-C, Moraten, Rubeovax, Schwarz, and Zagreb are vaccine strains of the Edmonston lineage, whereas CAM-70, Changchun-47, Leningrad-4 and Shanghai-191 were derived from 4 different wild-type isolates.
