Eight of 10 typical cases of contagious caprine pleuro-pneumonia in Oman yielded strain F38-like mycoplasmas from the lungs in high titre, but no other mycoplasmas: both negative animals had been treated with tylosin shortly before death. Among 21 other lungs examined three of six cases of acute pneumonia yielded Mycoplasma ovipneumoniae; one also yielded M capricolum. M ovipneumoniae was also isolated from all eight cases of chronic pneumonia sampled from an abattoir, and from the lungs of three animals which died without overt signs of pneumonia. A single isolate of M arginini and three of unidentified mycoplasmas were also obtained from goats with and without pneumonia. Various bacterial species were isolated, none of which predominated. Antibodies to M mycoides subspecies capri (M m capri) and strain F38 were detected in sera from eight different sources. Assuming titres of 1 in 40 or more as positive in the indirect haemagglutination test used, 29 per cent of 422 serum samples had antibodies to M m capri alone, 2.6 per cent to strain F38 alone and 3.6 per cent to both organisms. These results confirm the presence of F38-like mycoplasmas in Oman, and indicate also widespread infection with M m capri. The role of the latter in caprine pneumonias in Oman requires elucidation.
阿曼10例典型传染性山羊胸膜肺炎病例中有8例，其肺部产生了高滴度的F38样支原体，但未发现其他支原体：两只检测结果为阴性的动物在死亡前不久曾用泰乐菌素治疗。在检查的其他21个肺脏中，6例急性肺炎病例中有3例分离出绵羊肺炎支原体；1例还分离出山羊支原体。从一家屠宰场采集的所有8例慢性肺炎病例的肺脏以及3只无明显肺炎症状死亡动物的肺脏中也分离出了绵羊肺炎支原体。还从患肺炎和未患肺炎的山羊中分别分离出1株精氨酸支原体和3株未鉴定的支原体。分离出了多种细菌，但均未占主导地位。在来自8个不同来源的血清中检测到了抗山羊支原体丝状亚种（M m capri）和F38株的抗体。在所用的间接血凝试验中，假设滴度为1:40或更高为阳性，则422份血清样本中，29%仅对M m capri有抗体，2.6%仅对F38株有抗体，3.6%对两种病原体均有抗体。这些结果证实了阿曼存在F样支原体，并表明M m capri也广泛感染。后者在阿曼山羊肺炎中的作用有待阐明。
