      extent of the condition and herd risk factors.

AB  - Cranioventral pulmonary consolidation (enzootic pneumonia-like lesions) and 
      chronic pleuritis (CP) are common findings in slaughtered pigs. Pleural lesions 
      involving dorsocaudal lobes are suggestive of pleuropneumonia due to 
      Actinobacillus pleuropneumoniae. In this report the results of an abattoir survey 
      of pleuritis and pulmonary lesions in pigs is presented with a focus on herd risk 
      factors. A total of 4889 animals, ranging in age from 9 to 10 months, from 48 
      batches of pigs belonging to an equal number of herds, were included in the 
      study. Bronchopneumonic lesions suggestive of enzootic pneumonia (EP-like 
      lesions) were detected in 46.4% of the examined lungs. The EP-like lesion average 
      value for all lungs was 1.03 (95% CI 0.98-1.08), ranging from 0.17 to 2.56 among 
      the 48 batches; 47.5% of lungs showed chronic pleuritis. Dorsocaudal pleuritis 
      suggestive of recovered pleuropneumonia (SPES score >/=2) was found in 25.1% of the 
      lungs. The mean SPES (slaughterhouse pleuritis evaluation system) value of the 
      overall 4889 lungs was 0.83 (95% CI 0.78-0.86). The mean SPES value of the 
      batches ranged from 0.04 to 1.87. The mean Actinobacillus pleuropneumoniae index 
      of all studied batches was 0.61 (95% CI 0.51-0.71), ranging from 0 to 1.84. Blood 
      samples were collected from each herd to evaluate antibody titres to Mycoplasma 
      hyopneumoniae, A. pleuropneumoniae, Aujeszky's disease virus, porcine 
      reproductive and respiratory syndrome virus (PRRSV), and swine influenza virus. 
      Herd characteristics were recorded using a questionnaire given to the farmers. A 
      multivariable analysis was conducted to identify risk factors for pleuritis and 
      EP-like lesions. High dorsocaudal pleuritis was associated with A. 
      pleuropneumoniae seroprevalence and history of A. pleuropneumoniae isolation from 
      pneumonic lungs of dead animals. Vaccination of weaners at 3-5 weeks of age 
      against PRRS using a modified live vaccine was associated with a reduction in the 
      percentage of cranioventral pulmonary consolidation (EP-like lesions).
