畜禽呼吸道黏膜屏障的结构和功能及其改善措施

呼吸道黏膜屏障是机体防御的重要屏障,主要包括机械屏障、化学屏障、微生物屏障和免疫屏障,各屏障有机地结合在一起,共同阻止有害物质的侵袭,保护呼吸道健康。畜禽舍内粉尘、有害气体及温度、湿度等因子容易引起呼吸道疾病,导致呼吸道黏膜损伤,加重畜禽病情,甚至诱发脏器病理损伤。本文主要通过总结呼吸道黏膜屏障的结构和功能以及改善畜禽呼吸道黏膜屏障的措施,为深入研究呼吸道黏膜屏障进而防治畜禽呼吸道疾病提供理论依据。

Structure and Functions of Mucosal Barrier of Respiratory Tract in Livestock and Poultry and Its Improvement Measures

Respiratory mucosal barrier is an important barrier to the body's defense, including mechanical barriers, chemical barriers, microbial barriers and immune barriers, organically combined together to prevent the invasion of harmful substances to protect the respiratory health.Dust, harmful gases and temperature, humidity and other factors in animal house are easily lead to respiratory diseases of livestock and poultry, resulting in respiratory mucosal injury, aggravate severity of the disease, and even induce organ pathology injury.In this paper, we summarized the structure and functions of respiratory mucosal barrier and the measures to improve the mucosal barrier of the respiratory tract in livestock and poultry in order to provide theoretical basis for further study of respiratory mucosa barrier and prevention of respiratory diseases of livestock and poultry.
