    Haemophilus influenzae remains a major cause of disease worldwide requiring continued study. Recently, isolates of Streptococcus pneumoniae and Moraxella catarrhalis, but not H. influenzae, were reported to survive long-term ultra-freeze storage in STGGB. We show that nontypeable H. influenzae isolates survive for up to 20. years when thawing is avoided.
