Prevention of Erysipelas Diseases at the Adventure World

Abstract

　At the Adventure World, there were a few cases of erysipelas infections in three species of cetaceans, such as bottlenose dolphin, pacific white-sided dolphin, and false killer whale. One of them was occurred that all five cetaceans were suffered from cutaneous lesions of erysipelas between 1990 and 1998. After several years, second case was occurred from 2006 to 2008, 2 bottlenose dolphins and 2 pacific white-sided dolphins died at 3-4 days after onset of erysipelas infectious disease. As a countermeasure, we started vaccination for erysipelas infection from November 2007. After the vaccination, one pacific white-sided dolphin died from erysipelas infections in March 2008. Since then there has been no record of erysipelas infection therefore we are considering that vaccination has a certain effect on prevention of this infectious disease.
