An outbreak of verminous pneumonia due to Dictyocaulus viviparus in a herd of mature, lactating, dairy cows in southern Ontario is described. The fact that the herd had been closed to new additions for ten years and had never experienced clinical disease due to D. viviparus in the past makes the occurrence of this herd problem difficult to explain. Correlation of fecal Baermann analysis for D. viviparus larvae with the progress of anthelmintic treatment is discussed. It is suggested that certain climatological variations in combination with unique, immunological aspects of D. viviparus infection may have contributed to the development of clinical disease in this herd.
本文描述了安大略省南部一群成熟泌乳奶牛群中由胎生网尾线虫引起的蠕虫性肺炎疫情。该牛群已封闭十年未引入新牛，且过去从未因胎生网尾线虫出现过临床疾病，这使得此次牛群问题的发生难以解释。文中讨论了粪便贝尔曼分析法检测胎生网尾线虫幼虫与驱虫治疗进程的相关性。研究表明，某些气候学变化与胎生网尾线虫感染独特的免疫学因素相结合，可能促使了该牛群临床疾病的发生。
