Summary

The authors studied the viability of Haemophilus spp. preserved for 5 to 12 months at -70 °C in different media. Three clinical isolates of both H. influenzae and H. parainfluenzae were used. No significant changes in antimicrobial susceptibility were observed after 5-month storage in any medium. After 12 months, trypticase soy broth (TSBG) with glycerol and horse serum appeared to be the most suitable cryopreservation medium for the six strains tested.
