Abstract

An experimental chick hatcher designed to filter recycled ventilation air was tested for its effectiveness in reducing the number of viable airborne microorganisms. Chicks in a filtered hatcher and a control hatcher (no filter) were artificially contaminated with Serratia marcescens as ventilation air was recycled in the hatchers for twelve hours. The number of viable S. marcescens particles in the filtered air of the conditioning chamber was less than detectable. The number of viable airborne S. marcescens particles in the hatching chamber of the filtered hatcher indicated a reduction of greater than 90 percent over the number in the unfiltered hatcher. The filter was effective in reducing the number of airborne particles carrying viable S. marcescens organisms in the hatcher.

摘要

一个旨在过滤循环通风空气的实验性雏鸡孵化箱，就其在减少空气中存活微生物数量方面的有效性进行了测试。在过滤孵化箱和对照孵化箱（无过滤器）中的雏鸡，在孵化箱内循环通风空气12小时的过程中，被人为接种了粘质沙雷氏菌。调节室内过滤空气中存活的粘质沙雷氏菌颗粒数量低于可检测水平。过滤孵化箱孵化室内空气中存活的粘质沙雷氏菌颗粒数量表明，与未过滤的孵化箱相比减少了90%以上。该过滤器在减少孵化箱内携带存活粘质沙雷氏菌的空气颗粒数量方面是有效的。
