Additional Post Mortem Findings
The Phoenix Zoo necropsy report listed the following additional findings: significant hemorrhagic congestion within right lung, pinpoint spots of hemorrhage on surface of heart overlying area of coronary vessels, multiple small lacerations/abrasions on limbs and trunk, small amount of serosanguinous ascites (accumulation of blood and serum in abdomen), areas of mild hemorrhage/ulceration in body of stomach, enlarged liver extending into caudal (hind part) abdomen, tape worms present in lumen (cavity where digested food passes and where nutrients are absorbed) of small intestine, and the adrenals appeared mildly large and cystic.
The University of Arizona’s additional findings were as follows: The acute myocardial (muscle tissue of heart) necrosis (scarring caused by infection) suggests either ischemia/hypovolemia (Insufficient supply of blood to an organ/State of decreased blood volume in blood plasma characterized by salt depletion) or possibly injury secondary to chronic catecholamine (Play an important role in body’s physiological response to stress. Their release increases the rate and force of muscular contractions of heart) effects on the myocardium (Middle and thickest layer of heart wall). The duodenal erosion ( lining of upper portion of small intestine into stomach erodes and develops a sore) is probably related to stress.
The additional findings of the University of California report were: He had lesions compatible with mild bacteremia (bacteria in blood); endocarditis (Inflammation of heart) and tubulointerstitial nephritis (Inflammation that affects the tubules of kidneys and the tissues that surround them. The most common cause in humans is an allergic reaction to a drug. The disease can also be caused by a bacterial infection in the kidneys) that may have originated from the enteric lesions (lesions in small intestine).
Macho B was sixteen years old when he was euthanized. He was one of the oldest jaguars to be documented in the wild.
