Six cases of verminous pneumonia in goats due to Muellerius sp. were reviewed. In only one case was the pneumonia diagnosed antemortem. The gross necropsy findings and histopathology revealed a widespread interstitial pneumonia in all the cases. There was variability in the local reaction around the parasites from almost none in the mildest cases to larger focal accumulations of macrophages and mononuclear inflammatory cells. Only in the severest cases were eosinophils seen and even then were scattered and few in number. No nodular lesions were seen associated with the parasites. The pathology of the pulmonary lesions in goats appears to be more commonly of the diffuse type and therefore significantly different from the nodular lesion usually observed in sheep.
回顾了6例由缪勒属线虫引起的山羊蠕虫性肺炎病例。仅1例在生前诊断出肺炎。大体尸检结果和组织病理学显示，所有病例均有广泛的间质性肺炎。寄生虫周围的局部反应存在差异，从最轻微病例中几乎没有反应到巨噬细胞和单核炎性细胞的较大局灶性聚集。仅在最严重的病例中可见嗜酸性粒细胞，即便如此，数量也很少且呈散在分布。未见与寄生虫相关的结节性病变。山羊肺部病变的病理学表现似乎更常见为弥漫型，因此与通常在绵羊中观察到的结节性病变有显著差异。
