We evaluated survival in WHO-recommended STGG storage medium of bacteria causing respiratory-tract infection. Streptococcus pneumoniae and Moraxella catarrhalis survived as single and mixed isolates stored at -70°C for 12.5 years, but Haemophilus influenzae less than 4 years. All the bacteria survived in the nasopharyngeal specimens at -70°C for 11 years.
我们评估了在世界卫生组织推荐的用于呼吸道感染细菌的 STGG 储存培养基中的细菌存活率。肺炎链球菌和卡他莫拉菌作为单一菌株和混合菌株在 -70°C 下储存 12.5 年仍存活，但流感嗜血杆菌存活时间不到 4 年。所有细菌在 -70°C 的鼻咽标本中储存 11 年仍存活。
