To evaluate the disinfection effectiveness of slightly acidic electrolysed water (SAEW, pH 6·25-6·53), a new environmental friendly agent for inactivating micro-organisms adhered to the facility and aerosolized in the air of the swine barns and to explore the application of SAEW in livestock industries.
Bacteria and fungi were isolated from the swine house air and treated by SAEW. The SAEW solution was flushed onto surfaces and sprayed within the whole swine barn. SAEW with an available chlorine concentration (ACC) of 300 mg l(-1) can inhibit isolated microbes completely. The usage of SAEW (300 mg l(-1) ) resulted in a significant (P < 0·05) reduction in microbes on the wall, rail and floor after flushing disinfection. Additionally, spraying SAEW at an ACC of 300 mg l(-1) reduced 59% of the airborne organisms in 30 min and kept the population of microbes at a reduced level for at least 8 h. SAEW treatment also reduced pathogens on surfaces (P < 0·03) after spraying disinfection except on the surface of the wall.
SAEW may be a potential alternative disinfectant to reduce infections in swine barns.
The results of this study provide information on the antimicrobial efficiency of SAEW on the airborne bacteria and fungi in swine barns.
评估弱酸性电解水（SAEW，pH 值为 6.25-6.53）的消毒效果，这是一种新型环保剂，可有效消灭附着在猪舍设施上和空气中的微生物，并探索其在畜牧业中的应用。
从猪舍空气中分离出细菌和真菌，并使用 SAEW 进行处理。将 SAEW 溶液冲洗到表面并喷洒在整个猪舍内。有效氯浓度（ACC）为 300mg/L 的 SAEW 可完全抑制分离出的微生物。使用 ACC 为 300mg/L 的 SAEW 冲洗消毒后，墙壁、栏杆和地板上的微生物数量显著减少（P<0.05）。此外，以 ACC 为 300mg/L 喷洒 SAEW 可在 30 分钟内减少 59%的空气传播微生物，并使微生物数量保持在较低水平至少 8 小时。喷雾消毒后，SAEW 处理还可降低表面上的病原体（P<0.03），但墙壁表面除外。
SAEW 可能是一种替代消毒剂，可以减少猪舍中的感染。
本研究结果提供了有关 SAEW 对猪舍空气中细菌和真菌的抗菌效率的信息。
