Preservation of strains is important to further studies and characterization; we have shown a technique of long-term preservation of Neisseria spp. and Haemophilus spp. by freezing cotton tip swabs impregnated with fastidious organisms at −80 °C without the addition of cryoprotectants.

长期储存耐细菌（Neisseria spp。和Haemophilus spp。），并在-80°C下保存拭子。

菌株的保存对于进一步的研究和表征很重要；我们显示了一种长期保存奈瑟氏菌的技术。和嗜血杆菌属。在不添加冷冻保护剂的情况下，通过在-80°C下冷冻浸有耐高温微生物的棉签拭子。
