Saline suspensions of 11 aerobes and anaerobes were used to inoculate swabs from Port-A-Cul (Becton Dickinson), Culturette EZ (Becton Dickinson), and Copan Amies gel (Copan Diagnostics). Swabs were removed from transport devices at 0, 24, and 48 h postinoculation and then extracted by vortexing in 1.0 ml of saline, and organism survival was determined by quantitative plate counts. For the organisms tested, Culturette EZ allowed < 1% of the original inocula to be recovered after 24 h. Port-A-Cul was only slightly better. Recovery was best with the Copan gel-containing system. Agar gel swab systems may be useful for multipurpose transport devices.
使用11种需氧菌和厌氧菌的盐水悬液接种来自Port-A-Cul(碧迪医疗)、Culturette EZ(碧迪医疗)和科盼阿米斯凝胶(科盼诊断公司)的拭子。在接种后0、24和48小时从运输装置中取出拭子,然后在1.0毫升盐水中涡旋提取,通过定量平板计数确定微生物存活率。对于所测试的微生物,Culturette EZ在24小时后回收率低于原始接种量的1%。Port-A-Cul稍好一点。含科盼凝胶的系统回收率最佳。琼脂凝胶拭子系统可能适用于多用途运输装置。
