title: Prognosis for return to racing after recovery from infectious pleuropneumonia in thoroughbred racehorses: 70 cases (1984-1989).
abstract: OBJECTIVE
  To determine the percentage of Thoroughbred racehorses that would be capable of racing performance after recovery from infectious pleuropneumonia.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  70 Thoroughbred horses that had recovered from pleuropneumonia. Only horses < or = 5 years old and horses > 5 years old known to be in race training at the time of illness were included in the study.
  
  
  RESULTS
  Forty-three of the 70 (61%) horses raced after recovery, and 24 of the 43 (56%) won at least 1 race. Horses that required placement of an indwelling thoracic drain apparently did not have a worse prognosis than did horses that did not require placement of a drain. The prognosis for racing for horses that developed pleuropneumonia-associated complications (pulmonary abscess, cranial thoracic mass, bronchopleural fistula) was worse than the prognosis for horses that did not develop these complications. Duration of hospitalization was not considered indicative of outcome.
  
  
  CONCLUSIONS
  In Thoroughbreds, the prognosis for return to racing after recovery from uncomplicated pleuropneumonia appears to be good.
