Abstract
In confirmation of recent reports, coliphages were found in seven of 19 unselected samples of the currently licensed live virus vaccines. Coliphages and pseudomonas phages were found in 11 and 14, respectively, of the 20 bovine sera commonly used in the cell culture phase of virus vaccine production. The same lots of vaccine and serum were examined by the limulus assay for endotoxin, another product of bacterial contamination. Eighteen of 20 sera had detectable endotoxin like activity. These preliminary results suggest that endotoxin activity may serve as a sensitive indicator of residual products of previous bacterial contamination, including bacteriophages.
