RESUMO
Fecal specimens were obtained from wild birds and mammals in the eastern part of Shimane Prefecture, Japan, an area where serotype 1b, 2b, 3, and 4b strains of Yersinia pseudotuberculosis were found to be prevalent in humans. Each of 869 animals, including 259 wild birds and 610 wild mammals, was screened for yersiniae. A total of 37 strains of Y. pseudotuberculosis were isolated from 34 (5.6%) mammals, including 23 raccoon dogs (Nyctereutes procyonoides), eight deer (Cervus nippon), two hares (Lepus brachyurus), and one marten (Martes melampus), and from two (0.8%) birds, including one eastern spot-billed duck (Anas poecilorhyncha) and one wigeon (Anas penelope). The Y. pseudotuberculosis isolates collected belonged to virulence plasmid-positive (serotypes 1b, 2b, 3, 4b, and 6) and virulence plasmid-negative (serotype 5a) strains, the most predominant serotype being 4b. The close relationship between the regional distributions of Y. pseudotuberculosis in wild animals and humans suggests that wild animals are an important source of infection.
