| Abstract |
The transmission of Yersinia ruckeri has been investigated in steelhead trout using asymptomatic carriers of the causative bacterium of enteric redmouth disease. It was found that unstressed carrier fish did not transmit the bacterium to recipient fish to cause either an epizootic or produce new carrier fish. However, when the carriers were stressed with heat, the bacterium was transmitted from the carrier to recipient fish producing a lower intestinal carrier state but no deaths. Examination of experimentally infected fish to determine the number of carriers among the survivors indicated that the frequency varied as a function of time following infection. When immunized fish were challenged with Y. ruckeri they became temporary carriers of the bacterium for up to 3 days; but were not able to transmit the infection to healthy recipient fish. |
