Small particle aerosols of plate-grown Salmonella enteritidis and Salm. typhimurium were generated and maintained within a rotating drum at 75% relative humidity and 24 degrees C for 2 h. Plate-grown organisms were found to be more aerosol-stable than broth-grown organisms. Differences were observed between the two species; plate-grown Salm. typhimurium retained 100% viability after 2 h compared to approximately 70% for plate-grown Salm. enteritidis. A large proportion of cells of both serotypes remained viable in aerosols after 2 h, confirming the potential for airborne transmission for these organisms, e.g. within henhouses and during food processing.
将平板培养的肠炎沙门氏菌和鼠伤寒沙门氏菌制成小颗粒气溶胶，在转鼓内于相对湿度75%和24摄氏度的条件下维持2小时。发现平板培养的微生物比肉汤培养的微生物在气溶胶中更稳定。观察到这两个菌种之间存在差异；平板培养的鼠伤寒沙门氏菌在2小时后仍保持100%的活力，而平板培养的肠炎沙门氏菌约为70%。两种血清型的大部分细胞在2小时后在气溶胶中仍保持活力，证实了这些微生物通过空气传播的可能性，例如在鸡舍内和食品加工过程中。
