摘　　要：虾类消化道内生活着大量的细菌,它们成为虾体内不可或缺的重要组成部分,影响着机体的生长与健康。文章综述虾类消化道菌群的来源、组成以及作用。这些细菌主要来源于水体和食物中,常见的优势菌主要有发光杆菌属、弧菌属、气单胞菌属、假单胞菌属等。消化道菌群既可以为宿主提供营养、辅助消化,又能够拮抗病原、影响宿主的健康。它们的组成与变化既与虾类自身的种类、发育时期以及健康状况等因素有关,也受到包括水环境的盐度、温度、氧气浓度、饵料和药物等因素的影响。Microflora in shrimp digestive tract are an indispensable part of the host which influence the growth and health of the shrimp. This paper reviews their source, composition and functions. The bacteria usually include Photobacteriurn, Vibrio, Aerornonas and Pseudornonas from water and food. The intestinal microflora may not only improve digestive activity and nutrient absorption, but also prevent diseases by competitive exclusion or by stimulation of a defence reaction in the host. The factors such as shrimp species, environment and feed which can affect the microflora are also discussed in the paper.
