林蛙(Rana chinensis)俗称雪蛤、田鸡等,主要分布在我国东北地区,其肉质细嫩、味道鲜美,具有极高的营养价值和经济价值[1]。近年来,随着林蛙养殖规模的扩大,各种影响林蛙成活率的问题日渐增多,而由病原菌引起的林蛙爆发性传染病则是其中一个突出问题。就林蛙规模化养殖而言,对成蛙进行免疫的难度较大,但如果能在林蛙生长环境中培养特定的乳酸菌口服疫苗,从而对其进行免疫则较为容易。人
Rana chinensis commonly known as snow clams, frogs, etc., are mainly distributed in northeastern China, its delicate meat, delicious, with high nutritional value and economic value [1]. In recent years, with the expansion of forest frog breeding scale, various problems affecting the survival rate of Rana chensinensis have been increasing, while the outbreak of Rana chensinensis caused by pathogenic bacteria is one of the prominent problems. In the case of large-scale cultivation of Rana chensinensis, it is more difficult to immunize the frog, but it is easier to immunize the frog if it can be cultured in the environment of Rana chensinensis. people
