After necropsy of the surviving turkeys in a comparative vaccine study for fowl cholera, in the turkeys with only one lung lobe consolidated, a significantly (P < 0.01, chi square test) higher number of turkeys were found with a consolidation of the left lung lobe than with the right lung lobe. When the circumferences of the left and right pulmonary arteries 0.5 cm rostral from the bifurcation were measured and converted to cross-sectional area, the left pulmonary artery had an average area of 29.6 +/- 2.8 mm2, and the right pulmonary artery had an average area of only 22.9 +/- 2.8 mm2, which was nearly one-fourth smaller. This finding suggests that the left lung lobe receives more blood than the right lobe and that, during an acute Pasteurella multocida septicemia, it would receive more of this organism than the right lung lobe.
在一项针对禽霍乱的比较疫苗研究中,对存活的火鸡进行尸检后发现,在仅有一个肺叶出现实变的火鸡中,左肺叶实变的火鸡数量显著(P < 0.01,卡方检验)多于右肺叶实变的火鸡。当测量从分叉处向前0.5厘米处左右肺动脉的周长并换算为横截面积时,左肺动脉的平均面积为29.6 +/- 2.8平方毫米,而右肺动脉的平均面积仅为22.9 +/- 2.8平方毫米,几乎小了四分之一。这一发现表明,左肺叶比右肺叶接受更多血液,并且在急性多杀性巴氏杆菌败血症期间,左肺叶会比右肺叶接受更多这种病菌。
