摘要
牛数字皮炎（BDD）是一种蹄部传染性皮肤病，其特点是溃疡疼痛，导致奶牛跛行。在与 BDD 相关的细菌中，主要从 BDD 病变中分离出的子宫内膜法氏囊无细胞上清液（CFS）对噬菌体的生长刺激作用最大。在 F. endometrii 的 CFS 中检测到浓度为 45.4 mM 的丁酸，丁酸补充剂显著促进了噬菌体的生长。
The growth-stimulating factor of Treponema phagedenis from bovine digital dermatitis lesions
Bovine digital dermatitis (BDD) is an infectious skin disease of the hoof characterized by painful ulcerations that cause lameness in dairy cattle. Cell-free supernatants (CFS) of Falsiporphyromonas endometrii predominantly isolated from BDD lesions had the highest growth-stimulating effect on Treponema phagedenis among BDD-associated bacteria. Butyric acid was detected at a concentration of 45.4 mM in CFS of F. endometrii, and the growth of T. phagedenis was significantly promoted by butyric acid supplementation.
