Reported causes of death of captive killer whales (Orcinus orca). 1979

S H Ridgway

Inquiries were made to all oceanaria that maintain killer whales in North America. Causes of death determined at necropsy included mediastinal abscesses, pyometra, pneumonia, influenza, salmonellosis, nephritis, Chediak-Higashi syndrome, fungus infection, ruptured aorta, cerebral hemorrhage and a perforated post-pyloric ulcer. Captive females appear to have a higher rate of mortality than males. Growth rates for whales that died were greater than for those that survived.

D002591 Cetacea An order of wholly aquatic MAMMALS occurring in all the OCEANS and adjoining seas of the world, as well as in certain river systems. They feed generally on FISHES, cephalopods, and crustaceans. Most are gregarious and most have a relatively long period of parental care and maturation. Included are DOLPHINS; PORPOISES; and WHALES. (From Walker's Mammals of the World, 5th ed, pp969-70) Cetaceas
D002609 Chediak-Higashi Syndrome A form of phagocyte bactericidal dysfunction characterized by unusual oculocutaneous albinism, high incidence of lymphoreticular neoplasms, and recurrent pyogenic infections. In many cell types, abnormal lysosomes are present leading to defective pigment distribution and abnormal neutrophil functions. The disease is transmitted by autosomal recessive inheritance and a similar disorder occurs in the beige mouse, the Aleutian mink, and albino Hereford cattle.
