Infection with a novel gammaherpesvirus in northern elephant seals (Mirounga angustirostris).

Causes of Live Strandings of Northern Elephant Seals (Mirounga angustirostris) and Pacific Harbor Seals (Phoca vitulina) Along the Central California Coast, 1992-2001

Between January 1992 and December 2001 a total of 1,277 northern elephant seals (Mirounga angustirostris) and 940 Pacific harbor seals (Phoca vitulina) were stranded live along the central California coast. By examining medical records for each of the stranded seals, the primary cause of stranding and the secondary factors contributing to stranding were determined. The majority (88.3%) of anima...

Leptospirosis in northern elephant seals (Mirounga angustirostris) stranded along the California coast.

Leptospirosis was identified in six northern elephant seals (Mirounga angustirostris) that were stranded in 1995 along the coast of California (USA). Histologic lesions in all seals included tubulointerstitial nephritis with tubular degeneration and necrosis. Infection was confirmed through identification of spirochetes using an immunohistochemical stain for Leptospira sp. antigens. One affecte...

Call directionality and its behavioural significance in male northern elephant seals, Mirounga angustirostris

Angiotensin II and aldosterone increase with fasting in breeding adult male northern elephant seals (Mirounga angustirostris).

The renin-angiotensin-aldosterone system (RAAS) appears to contribute significantly to osmoregulation of fasting northern elephant seal (Mirounga angustirostris) pups; however, RAAS has not been characterized in fasting adult seals. Therefore, this study examined the contribution of RAAS to water turnover rates in fasting adult male northern elephant seals. Blood samples were obtained twice dur...

Pharmacokinetic Study of Oral Ε-aminocaproic Acid in the Northern Elephant Seal (mirounga Angustirostris).

ε-Aminocaproic acid (EACA) is a lysine analogue antifibrinolytic drug used to treat bleeding disorders in humans and domestic animals. Its use in zoological medicine is rare, and dosage is anecdotal. One possible application of EACA is to treat bleeding associated with prepatent Otostrongylus arteritis in Northern elephant seals ( Mirounga angustirostris ) presenting to wildlife rehabilitation ...
