• Meningococci, pneumococci, and hemophilic bacilli may be stored at -70 degrees C. Only half (54.4 percent) of Meningococcal cultures were viable after 11 months storage, 41.6 percent retained their serologic properties. Conditions for stable long storage of meningococci at -70 degrees C are to be searched for. Pneumococci retained their initial parameters for 8 months, this permitting recommendation of such storage for these bacteria. No data on the possibility of hemophilic bacilli storage is available yet.
