Effective Treatment for Improving the Survival Rate of Raccoon Dogs Infected with Sarcoptes scabiei

Sarcoptes scabiei is one of the important external parasites. Although ivermectin is the recommended treatment, many raccoon dogs (Nyctereutes procyonoides) that were rescued and brought to the Kanazawa Zoological Gardens (Yokohama, Japan) have died because of S. scabiei, even after receiving single ivermectin treatment. Therefore, supportive treatment should be required. The present study revealed the number of animals that survived was greater after the administration of ivermectin along with an antibiotic for all raccoon dogs, as well as following the administration of fluid therapy to the debilitated raccoon dogs infected with S. scabiei, immediately after the rescue. During the initial period, treatment to improve the general clinical condition was required prior to deworming treatment for S. scabiei.
