This year, our staff and volunteers treated more patients with leptospirosis than ever before. Leptospirosis is a bacterial kidney disease that can be fatal if left untreated. California sea lion Baxter came into our care with all the tell-tale signs: drinking water, flippers tucked against his belly and malnourished. He also had a fishing hook,line and lure lodged in his mouth.

Baxter was in bad shape. First, our expert veterinary team removed the hook and line so Baxter could eat. Then they prescribed him medications and a herring diet. After two months, Baxter recovered and received a second chance at life in his ocean home.

Our scientists continually learn about leptospirosis by treating patients like Baxter. These cases help us better understand what causes an outbreak, how we can improve treatment for infected animals and how to protect humans as well.
