Infectious Type of Experimental Rimerella anatipestifer Infection
2001
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.
