The likely culprit is a toxic algal bloom, fueled by warmer ocean temperatures.

That's right, California sea lions. As populations of native Steller sea lions decline, Maniscalco says a growing number of California sea lions are showing up on Steller sea lion rookeries and haul-outs across the state. According to his research, some 33 sightings have been recorded. And some of those California sea lions have made their way as far west as the Pribilof Islands in the Bering Sea.

A leptospirosis bacteria outbreak is making sea lions sick along the Oregon Coast, so state officials are warning people and their dogs to stay away from the animals. The outbreak began in September and likely will last into December, said Jim Rice, a researcher at Oregon State University.

Leptospirosis infections, caused by Leptospira bacteria, occur in people and animals around the world, but different strains of the bacteria may vary in their ability to cause disease and to jump between species. Now, researchers have for the first time described the characteristics of the Leptospira variants that infect cattle in Uruguay.
