Many wild southern sea otters in California are infected with the parasite Toxoplasma gondii, yet the infection is fatal for only a fraction of sea otters, which has long puzzled the scientific community. A study from the University of California, Davis, identifies the parasite’s specific strains that are killing southern sea otters, tracing them back to a bobcat and feral domestic cats from nearby watersheds.

Paving the Way for Pathogens

Higher levels of rainfall and coastal development increase the risk of disease-causing organisms flowing to the ocean, according to a study from the University of California, Davis. The study advances earlier work by tracking the parasite T. gondii to see how human-driven land-use change and rainfall might be impacting pathogen movement from land to sea.
