摘要: 1. The significance of airborne transmission in epidemics infectious diseases the livestock production industry remains unclear. study therefore investigated shedding route (faeces vs. exhaled air) a vaccine strain bursal disease virus (IBDV) by broilers and emission virus. 2. experimental room contained 526 which were orally inoculated at age 20 d. was sampled three different bioaerosol samplers: Andersen six-stage impactor, all-glass impinger (AGI-30) OMNI-3000. 3. Infected started to shed faeces on d 5 post inoculation (PI), stopped 12 PI. faecal remained detectable for least two after drying under broiler conditions. No detected air broilers. 4. Airborne collected 5, 8 PI 20 cm above floor, exhausted air. rates IBDV 4·0 log10 50% tissue culture infectious...
