| Popis: | Free-ranging raccoon dogs (Nyctereutes procyonoides) from Nogeyama Zoological Gardens, Kanazawa Zoological Gardens, and Yokohama Zoological Gardens frequently rescued dogs having Sarcoptes scabiei infestation. However, the epidemiology of S. scabiei infestation has not yet been elucidated. In the present study, we investigated the epidemiology of S. scabiei infestation in raccoon dogs and its influence on the population of masked palm civets in Yokohama, Japan. We examined records of raccoon dog rescue between 1981 and 2010 and classified the dogs into the following 4 categories on the basis of the reason for rescue: dogs with S. scabiei infestation, scabies-infested dogs involved in car accidents, uninfested dogs involved in car accidents, and other reasons for rescue. We found that the number of dogs rescued due to car accidents and other reasons increased from 1989 onwards, and an S. scabiei outbreak was recorded since 1993. The infestation spread from the southern to the northern regions of Yokohama. The total number of raccoon dogs rescued annually peaked in 1995 and declined thereafter. The number of masked palm civets (Paguma larvata) rescued gradually increased with a decline in the number of raccoon dogs rescued. In the present study, we revealed the epidemiology of S. scabiei infestation in the raccoon dog. The outbreak might be induced by the increased population density, and the infestation spread immediately from the southern to the northern regions of Yokohama since 1993. Further, the population of masked palm civets may have increased due to the decrease in the population of the raccoon dog. |
