Fatal leptospirosis in southern sea otters from Central California: pathologic findings and detection of Leptospira interrogans

Recent retrospective analysis of southern sea otters (Enhydra lutris nereis) in Central California has revealed a significant prevalence of fatal leptospirosis, linked to *Leptospira interrogans* serovar Pomona. Examining cases from 2005-2025, researchers identified leptospiral infection in 74% of suspected cases via PCR, with 71% of infected otters stranding during periods of increased rainfall, suggesting potential land-to-sea transmission. These findings underscore the importance of investigating disease transmission dynamics to mitigate sea otter mortality and protect this sentinel species.
