A 1978-79 survey of the incidence of thoracic cavity lesions at slaughter had shown that the overall incidence of pleurisy in Saskatchewan swine was low (2%). Therefore, in the summer of 1979 a comparison was made between the incidence of pleurisy in a herd of pigs chronically affected with Haemophilus pleuropneumoniae pneumonia and in animals from other herds slaughtered at the same time. The incidence of pleurisy in control pigs (3.6%) was slightly higher than in the large scale survey but in the pigs from the Haemophilus infected herd it was almost four times as great (13.3%). In the same herd the survivors of a batch of pigs which had been decimated by more severe disease showed an incidence of 32% pleurisy. The economic implications of these findings are detailed and discussed.
一项1978 - 1979年针对屠宰时胸腔病变发生率的调查显示,萨斯喀彻温省猪群中胸膜炎的总体发生率较低(2%)。因此,在1979年夏天,对一群长期感染胸膜肺炎放线杆菌肺炎的猪群中胸膜炎的发生率与同时期屠宰的其他猪群中的发生率进行了比较。对照猪群中胸膜炎的发生率(3.6%)略高于大规模调查中的发生率,但感染胸膜肺炎放线杆菌猪群中的发生率几乎是其四倍(13.3%)。在同一猪群中,一批因更严重疾病而大量死亡的猪的幸存者中,胸膜炎的发生率为32%。这些研究结果的经济影响将详细阐述并进行讨论。
