Rainbow trout were continuously exposed to sublethal PCB concentrations for 30 days and infected with Aeromonas hydrophila or sham-injected. Mortality of PCB-exposed infected fish was significantly lower than control-infected fish. Survivors of the infection at all exposure concentrations had elevated leucocrits and decreased haematocrits compared with their respective shams. PCB-exposed sham fish had significantly higher leucocrits at both concentrations and significantly lower haematocrits compared with control-shams.
