Liver abscessation is an important metabolic disorder that commonly afflicts cattle consuming cereal-based, high-concentrate diets. Economic ramifications of liver abscessation are substantial, and include liver condemnation, decreased body weight gain, poorer efficiency of feed utilization, reduced carcass yield, and impairments in operational efficiency of commercial abattoirs. The etiological agent most commonly associated with liver abscesses is , which is an anaerobic, Gram-negative, nonmotile, nonsporulating, and rod-shaped (pleomorphic) bacterium. is one of the major proteolytic species of bacteria in the rumen, and it is believed to have a major role in degradation of dietary lysine. Herein we describe interactions between lysine and . , and the potential role of dietary lysine as an enabling factor in the development of liver abscesses in cattle.
肝脓肿是一种重要的代谢紊乱疾病，常见于食用谷物类高浓缩日粮的牛群。肝脓肿的经济影响巨大，包括肝脏被判定不合格、体重增加减少、饲料利用效率降低、胴体产量下降以及商业屠宰场运营效率受损。最常与肝脓肿相关的病原体是 ，它是一种厌氧、革兰氏阴性、无运动性、不产芽孢的杆状（多形）细菌。 是瘤胃中主要的蛋白水解细菌种类之一，据信它在日粮赖氨酸的降解中起主要作用。在此我们描述赖氨酸与 的相互作用，以及日粮赖氨酸作为牛肝脓肿发展中的促成因素的潜在作用。
