牛蛙常见病原菌对青蛙的致病性研究

A STUDY ON THE PATHOGENICITY OF BULLFROGS COMMON PATHOGENIC BACTERIA TO FROGS

用克氏耶尔森氏菌、奇异变形菌、不动杆菌和爱德华氏菌等４株牛蛙致病菌，在相同条件下分别感染牛蛙和青蛙，均可发病和死亡，且两种蛙感染同一病原菌后的症状及病变也相同，证实青蛙对牛蛙的常见传染病具有易感性，是牛蛙病发生的重要传染来源之一．

Under the same conditions ,the challenge test showed that four strains of bullfrogs pathogens (Yersinia kristensenii,Proteus mirabilis, Acinelobacter calcoaceticus and Edwardsiella tarda) could make the bullfrog and frog fall ill and cause death and that the symptoms and pathological changes of the two kind frogs caused by the same pathogenic bacterium were the same.It proved that the frogs were easily infected with bullfrogs common infectious diseases,and were one of the important infectious sources of the bullfrogs diseases.
