A serological indication of some pathogens in the beluga whale Delphinapterus leucas population from Sakhalinsky Bay, Sea of Okhotsk (Sakhalin-Amur aggregation) was performed in 2013-2014 after the largest, in the history of observations, flood of the Amur River. The percent of this population immune to causative agents of clonorchosis was 25.6%; toxoplasmosis, 11.5%; brucellosis, 38.5%; tuberculosis, 30.8%; cetacean morbillivirus infection, 16.7%; and to alpha and gamma herpes viruses each, 21.8%.

Key words: beluga whale, Delphinapterus leucas, clonorchosis, toxoplasmosis, brucellosis, tuberculosis, cetacean morbillivirus, herpes, Amur, Sakhalinsky Bay, Sea of Okhotsk.
