The air of loose-boxes which had previously held pigs infected with foot-and-mouth disease was sampled for virus after various procedures. Removal of infected pigs led to a 12- to 16-fold reduction in the amount of virus after 5 min. and a 400-fold reduction after 60 min. After heavy spraying (1.2 mm. of water in 5 min.) the amount of virus was reduced 500-fold compared to 30-fold after light spraying (0.20 mm. of water in 5 min.). The partition of infectivity associated with particle size was measured. The partition found after light spraying was similar to that found 5 min. after the pigs had been removed. Heavy spraying brought about a reduction in the infectivity associated with the large particles (> 6 mum.) but had no effect on particles less than 3 mum. A similar partition was found 60 min. after the pigs had been removed. The findings are discussed in relation to the spread of foot-and-mouth disease by the airborne route.
在进行各种操作后，对先前饲养过感染口蹄疫猪只的散养栏空气进行病毒采样。清除感染猪只后，5分钟内病毒量减少了12至16倍，60分钟后减少了400倍。重度喷雾（5分钟内喷水1.2毫米）后，病毒量减少了500倍，而轻度喷雾（5分钟内喷水0.20毫米）后减少了30倍。测量了与颗粒大小相关的感染性分布情况。轻度喷雾后发现的分布情况与猪只被移走5分钟后发现的相似。重度喷雾使与大颗粒（>6微米）相关的感染性降低，但对小于3微米的颗粒没有影响。在猪只被移走60分钟后发现了类似的分布情况。结合口蹄疫通过空气传播的途径对这些发现进行了讨论。
