First Report of Natural Co-Infection by Gyrodactylus lenoki and Lactococcus garvieae in Farmed Rainbow Trout (Oncorhynchus mykiss): Field and Experimental Evidence for Parasite-Enhanced Mortality, With a COI-Morphology Species Discordance.
It is well established that ectoparasite infection can increase the pathogenicity of, and host susceptibility to, bacterial infections in fish, including rainbow trout; however, no interaction between the ectoparasite Gyrodactylus and the bacterium Lactococcus garvieae has previously been documented. This study present...
