第 1 页，共 6 页 重要性 牛结核病是牛的一种慢性细菌性疾病，偶尔会影响其他哺乳动物物种。这种疾病是一种重要的人畜共患病，通常通过吸入气溶胶或摄入未经高温消毒的牛奶传播给人类。在发达国家，根除计划已经减少或消除了牛的结核病，人类疾病现在已经很少见；然而，野生动物体内的水库可能使彻底根除变得困难。牛结核病在欠发达国家仍然很常见，牲畜死亡、慢性疾病和贸易限制可能造成严重的经济损失。在某些情况下，这种疾病也可能对濒临灭绝的物种构成严重威胁。
page 1 of 6 Importance Bovine tuberculosis is a chronic bacterial disease of cattle that occasionally affects other species of mammals. This disease is a significant zoonosis that can spread to humans, typically by the inhalation of aerosols or the ingestion of unpasteurized milk. In developed countries, eradication programs have reduced or eliminated tuberculosis in cattle, and human disease is now rare; however, reservoirs in wildlife can make complete eradication difficult. Bovine tuberculosis is still common in less developed countries, and severe economic losses can occur from livestock deaths, chronic disease and trade restrictions. In some situations, this disease may also be a serious threat to endangered species.
