Summary
During four breeding seasons (2004-2008), 78 necropsy examinations were
performed on South American fur seal pups (Arctocephalus australis
gracilis) found dead on Guafo Island, southern Chile (43º360S, 74º430W).
Tissue samples from 65 pups were examined microscopically. The primary
causes of death were enteritis with microscopical lesions of bacteraemia
(28.2%), starvation (23.1%), drowning (21.8%), trauma (19.2%) and
stillbirth (2.6%). Those pups with enteritis and microscopical lesions
of bacteraemia had haemorrhagic enteritis (100%), interstitial pneumonia
(86%), periportal hepatitis (73%) and vasculitis (18%). The pups that
died from starvation had atrophy of hepatocytes (61%) and cholestasis
(61%). The pups that drowned had bronchoalveolar oedema (65%) and
foreign bodies in the airways (65%). In animals that died from trauma,
the main lesions were skull fractures (67%). This range of pathological
findings is within what would be expected in a healthy otariid breeding
colony
