鸭疫里默氏菌病传染类型的研究

为了探明鸭疫里默氏菌病的传染类型，对两组不同日龄的鸭人工感染鸭疫里默氏菌，于接种感染后不同时间测定其血液中细菌含量，白细胞分类计娄的动态变化，并观察其临床症状和病理变化，结果表明：两组鸭在接种感染后一个较长的时间内其外周血液中细菌含量持续大幅度上升，并且在整个试验过程中都能在血液中查到鸭疫里默氏菌，结合临床症状和病理变化，得出鸭疫里默氏菌病是一种急性或亚急生的败血型传染病，在感染12－24h后出现菌血症，后瞬即发展为败血症经过。

Infectious Type of Experimental Rimerella anatipestifer Infection

To define the infectious type of Rimerella anatipestifer infection,subcutaneous injection at neck was used to artificially infect two group ducklings. The amount of RA and classified count about leukocyte in ducklings' peripheral blood were measured; the clinical manifestation and pathological changes were observed at different times after infection. The results show that in two group ducklings,the contents of RA continue increasing sharply in a longer time after infection,and there is RA in blood during the whole experiment. Combined with clinical and pathological manifestation,the experiments show that Rimerella anatipestifer infection is a septicemia-type infectious disease,which is acute or sub-acute. Bacteremia occurs in 12 to 24 hours after infection and it immediately develops into septicemia.
