Abstract
Summary
Evidence has been presented for the multiplication of pneumonia virus of mice in suckling hamster kidney cell culture monolayers. Virus was produced in low titer and caused CPE.

Propagation in cell culture appears to free PVM from the Riley Agent present as a contaminant of the animal passaged virus.
