      in diagnostic submissions.

AB  - During the period from January to December of 2001, a total of 3,391 swine sera 
      were submitted to our laboratory from 256 farms for the diagnosis of porcine 
      reproductive and respiratory syndrome (PRRS). The antibody to porcine 
      reproductive and respiratory syndrome virus (PRRSV) was tested by the indirect 
      immunofluorescent antibody (IFA) test. Of the 256 farms tested, 230 farms (89.8%) 
      were positive for the PRRSV antibody. The overall seroprevalence of the PRRSV 
      antibody was 52.1% (1765/3391). Most of the pigs seemed to be infected with PRRSV 
      at around 50 to 60 days old. The seroprevalence of the antibody became higher 
      with age, and peaked at around 100 days old. More than one-third of the adult 
      pigs, including boars, gilts, and sows, was positive for the PRRSV antibody. The 
      infection of PRRSV was chronic and confined to growers and/or finishers in most 
      farms. However, the antibody was detected in all production phases at some farms.
