      syndrome virus under controlled field conditions.

AB  - The aim of this study was to determine whether porcine reproductive and 
      respiratory syndrome virus (PRRSV) could be transmitted by aerosol under field 
      conditions. A total of 210 five-month-old PRRSV-negative pigs were housed in a 
      mechanically ventilated finishing facility containing 11 pens. Pen 1 contained 10 
      pigs (indirect contact controls) and pen 2 remained empty, providing a barrier of 
      2.5 m from the remaining pigs in pens 3 to 11. Fifteen or 16 of the pigs in each 
      of pens 3 to 11 were infected experimentally with a field isolate of PRRSV and 
      the other six or seven pigs served as direct contact controls. Five days after 
      the pigs were infected, two trailers containing 10 five-week-old PRRSV-naive 
      sentinel pigs were placed along each side of the building; one was placed 1 m 
      from the exhaust fans on one side of the building, and the other was placed 30 m 
      from the fans on the other side, and the sentinel pigs remained in the trailers 
      for 72 hours. They were then moved to separate buildings on the same site, 30 and 
      80 m, respectively, from the infected barn, and their PRRSV status was monitored 
      for 21 days. The direct and indirect contact control pigs became infected with 
      PRRSV but the sentinel pigs did not.
