The Gram-negative bacterium Actinobacillus pleuropneumoniae is the etiological agent of porcine pleuropneumonia, a respiratory disease that leads to severe economic losses in the swine industry. For years, scientists working with it have lacked a reliable genome sequence for comparison with other Actinobacillus species. Here, we report the draft genome sequence of A. pleuropneumoniae serotype 7 (strain S-8), isolated from swine lung in China in 1992.
