Bacteriophage contamination
in live poliovirus vaccine
by Hedda Milch†, F. Fornosi†
Abstract
Bacteriophages lytic for Escherichia coli strains were isolated from two
lots of oral poliomyelitis vaccine. From one ultracentrifuged sample bacteriophages
of four different plaque patterns were demonstrable with E. coli
C 3000 (2·8 × 102 PFU/ml) and E. coli (1·1 × 102 PFU/ml) as indicator
strains. The phage contamination of virus vaccines and its possible consequences
need further investigations.
