病原微生物的空气传播可造成人和动植物传染病的发生和流行。例如,在以色列废水唢灌区由肠道菌所致疾病发生率比对照区高2～4倍,并在其下风向350 m处空气中采到相应细菌。又如,贝氏柯克斯体(Q热病原体)或口蹄疫病毒可借助空气从一个牧场传播到下风向10 km乃至60 km处造成传 Airborne transmission of pathogenic microorganisms can cause the occurrence and prevalence of infectious diseases of humans, animals and plants. For example, the incidence of diseases caused by enterobacteria in wastewater irrigation areas in Israel is two to four times higher than in the control area, and the corresponding bacteria are taken in the air at a depth of 350 m downwind. In another example, C. bassiana (Q fever) or foot-and-mouth disease virus can be transmitted by air from one pasture to 10 km or even 60 km downwind
