Case report: six cases of verminous pneumonia (Muellerius sp.) in goats.
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.
