Pneumonic lungs of 56 calves were examined and 12 (21 per cent) of them yielded Streptobacillus moniliformis-like organisms. These organisms resembled those previously described as Bacillus actinoides or Actinobacillus actinoides. After intratracheal inoculation of cultures of two strains of these organisms, pneumonic consolidation developed in five out of six gnotobiotic calves and involved up to 16 per cent of the lung surface. Histological lesions of interstitial pneumonia were observed in the lungs of all six calves. Swellings at the site of the infection followed intradermal and subcutaneous inoculation of cultures of all strains in calves. Mice showed no signs of illness following intraperitoneal injection of three stains. The bacteriological findings suggested that a more appropriate name for these organisms would be Streptobacillus actinoides.
对56头犊牛的肺炎肺脏进行了检查,其中12头(21%)分离出念珠状链杆菌样微生物。这些微生物与先前描述的放线状芽孢杆菌或放线杆菌相似。对两株此类微生物的培养物进行气管内接种后,6头无菌犊牛中有5头发生气性实变,累及肺表面达16%。在所有6头犊牛的肺脏中均观察到间质性肺炎的组织学病变。对所有菌株的培养物进行皮内和皮下接种后,犊牛感染部位出现肿胀。小鼠腹腔注射三株菌后未出现疾病迹象。细菌学研究结果表明,这些微生物更合适的名称应为放线状链杆菌。
