Here we report the isolation of from a thoracic sample from a horse. A 17-y-old Hungarian Sport Horse mare was referred to the equine clinic of the University of Veterinary Medicine Budapest, Hungary, with suspected pleuritis. Upon arrival, the horse was febrile and had tachycardia, severe inspiratory dyspnea, and tachypnea. Thoracic ultrasonography revealed severe bilateral pleural effusion, and a large area of lung consolidation. After sampling of both hemithoraces, 66 L of turbid exudate were drained. Based on these findings, a tentative diagnosis of septic pleuritis was made, and the horse was immediately started on a course of broad-spectrum antibiotics, a NSAID, an anticoagulant, and intravenous fluids. Despite intensive care, the clinical parameters deteriorated, and the horse was euthanized 6 d later. Cytology confirmed septic pleuritis, with short chains or groups of coccoid bacteria. Anaerobic culture yielded gram-positive cocci from both hemithoraces in almost pure culture, which we identified as by 16S rDNA and whole-genome analysis. Additionally, we identified 4 previously unassigned sp. sequences as . Of these, 3 were obtained from aborted equine fetuses and a fourth from a donkey mastitis case, supporting the pathogenic nature of in these host species.
在此，我们报告从一匹马的胸腔样本中分离出[具体细菌名称未给出]。一匹17岁的匈牙利运动马母马因疑似胸膜炎被转诊至匈牙利布达佩斯兽医大学的马科诊所。到达时，这匹马发热，伴有心动过速、严重吸气性呼吸困难和呼吸急促。胸部超声检查显示双侧严重胸腔积液以及大面积肺实变。在对双侧胸腔进行采样后，排出了66升浑浊渗出液。基于这些发现，初步诊断为脓毒性胸膜炎，这匹马立即开始使用广谱抗生素、非甾体抗炎药、抗凝剂和静脉输液进行治疗。尽管进行了重症监护，但临床参数仍恶化，这匹马在6天后实施了安乐死。细胞学检查证实为脓毒性胸膜炎，可见短链或成组的球菌。厌氧培养从双侧胸腔中几乎纯培养出革兰氏阳性球菌，通过16S rDNA和全基因组分析，我们将其鉴定为[具体细菌名称未给出]。此外，我们将4个先前未分类的[具体细菌名称未给出]属序列鉴定为[具体细菌名称未给出]。其中3个序列来自流产的马胎儿，第4个来自一头驴的乳腺炎病例，这支持了[具体细菌名称未给出]在这些宿主物种中的致病性。
