Detailed postmortem examination of southern sea otters (Enhydra lutris nereis) found along the California (USA) coast has provided an exceptional opportunity to understand factors influencing survival in this threatened marine mammal species. In order to evaluate recent trends in causes of mortality, the demographic and geographic distribution of causes of death in freshly deceased beachcast sea otters necropsied from 1998–2001 were evaluated. Protozoal encephalitis, acanthocephalan-related… Expand
MORTALITY TRENDS IN NORTHERN SEA OTTERS (ENHYDRA LUTRIS KENYONI) COLLECTED FROM THE COASTS OF WASHINGTON AND OREGON, USA (2002–15)
TLDR
The continued stable growth of the Washington population of otters suggests they are able to tolerate current mortality rates, and infectious diseases, including morbilliviral encephalitis and leptospirosis, were documented for a limited number of years and then not detected again despite continued testing for these pathogens in necropsied animals.

Causes of Mortality of Northern Sea Otters (Enhydra lutris kenyoni) in Alaska From 2002 to 2012
Most of the world’s sea otters reside in Alaska, but there has never been an assessment of long-term mortality patterns for this keystone predator. We examined data collected from 780 northern seaExpand
Predators, Disease, and Environmental Change in the Nearshore Ecosystem: Mortality in Southern Sea Otters (Enhydra lutris nereis) From 1998–2012
TLDR
Findings from 15 years of southern sea otter necropsies will help improve estimates of population-level impacts of specific threats and optimize conservation and environmental mitigation efforts for this threatened species. Expand
A protozoal-associated epizootic impacting marine wildlife: mass-mortality of southern sea otters (Enhydra lutris nereis) due to Sarcocystis neurona infection.
TLDR
Evidence to support the point-source character of this event include the striking spatial and temporal clustering of cases and detection of high concentrations of anti-S. Expand
Transmission of Toxoplasma: clues from the study of sea otters as sentinels of Toxoplasma gondii flow into the marine environment.
TLDR
Investigation into the processes promoting T. gondii infections in sea otters will provide a better understanding of terrestrial parasite flow and the emergence of disease at the interface between wildlife, domestic animals and humans. Expand
Dramatic increase in sea otter mortality from white sharks in California
TLDR
The spatiotemporal patterns of shark-bitten sea otters match increases in pinniped populations, and the increased availability of marine mammal prey for white sharks may have led to more sharks spending more time in nearshore waters utilized by both sea Otters and pinnipeds. Expand
Bartonella spp. exposure in northern and southern sea otters in Alaska and California.
Since 2002, an increased number of northern sea otters (Enhydra lutris kenyoni) from southcentral Alaska have been reported to be dying due to endocarditis and/or septicemia with infection byExpand
ASSESSMENT OF CLINICAL PATHOLOGY AND PATHOGEN EXPOSURE IN SEA OTTERS (ENHYDRA LUTRIS) BORDERING THE THREATENED POPULATION IN ALASKA
TLDR
An increase in exposure to pathogens in sea otters in Kodiak, Alaska, USA, since the 1990s is revealed. Expand
Molecular characterization and prevalence of Halarachne halichoeri in threatened southern sea otters (Enhydra lutris nereis)
TLDR
This is the first documentation of H. halichoeri in southern sea otters and is suggestive of parasite exchange between sea otter and harbor seals and the sequenced genetic regions were sequenced and submitted to GenBank. Expand
Novel Bartonella infection in northern and southern sea otters (Enhydra lutris kenyoni and Enhydra lutris nereis).
TLDR
The study evaluated whether Streptococcus bovis/equinus (SB/E) and Bartonella infections were associated with UME-related disease characterized by VVE and septicemia in Alaskan sea otter carcasses recovered 2004-2008 and suggested that Bart onella spp. Expand

Coastal freshwater runoff is a risk factor for Toxoplasma gondii infection of southern sea otters (Enhydra lutris nereis).
TLDR
Evidence implicating land-based surface runoff as a source of T. gondii infection for marine mammals, specifically sea otters, is provided and provides a convincing illustration of pathogen pollution in the marine ecosystem. Expand
Butyltin residues in Southern Sea Otters (Enhydra lutris nereis) found dead along California coastal waters
Tributyltin (TBT) and its degradation products, mono- (MBT) and dibutyltin (DBT), were determined in liver, kidney, and brain tissues of adult southern sea otters (Enhydra lutris nereis) found deadExpand
Mortality of sea lions along the central California coast linked to a toxic diatom bloom
TLDR
Findings reveal that monitoring of mussel toxicity alone does not necessarily provide adequate warning of DA entering the food web at levels sufficient to harm marine wildlife and perhaps humans. Expand
Causes of mortality in California sea otters during periods of population growth and decline
TLDR
Elevated mortality appears to be the main reason for both sluggish growth and periods of decline in the threatened California sea otter population, and generally high proportion of deaths from infectious disease suggests this factor has contributed to the chronically sluggish growth rate. Expand
Biological characterisation of Sarcocystis neurona isolated from a Southern sea otter (Enhydra lutris nereis).
TLDR
This is the first isolation of S. neurona from the brain of a non-equine host and development in cell culture was by endopolyogeny and mature schizonts were first observed at 3 days postinoculation. Expand
Isolation and characterization of Sarcocystis from brain tissue of a free-living southern sea otter (Enhydra lutris nereis) with fatal meningoencephalitis
TLDR
A protozoan isolated in cell culture from the brain of a free-ranging sea otter with fatal meningoencephalitis was indistinguishable from S. neurona, based on parasite morphology, antigenic reactivity and molecular characterization. Expand
Shark‐inflicted mortality on a population of harbour seals (Phoca vitulina) at Sable Island, Nova Scotia
TLDR
It is estimated that shark-inflicted mortality on pups and adult females reduced pup production on Sable Island by 43 to 154 pups annually between 1993 and 1997, indicating that sharks are having an impact on Sables harbour seals. Expand
Risk factors associated with the presence of Sarcocystis neurona sporocysts in opossums (Didelphis virginiana).
TLDR
Of the factors examined, season and body condition score were associated with increased odds of an animal harboring sporocysts, and Variables that wereassociated with the presence of S. neurona sporocyts were used in logistic regression analysis. Expand
