[A new zoonosis--investigation of Gardnerella vaginalis disease of fox. I. Causative agent isolation and artificial infection].

It is the first time that this paper reports on using improved rabbit blood agar culture medium to isolate 145 strains Gardnerella vaginalis from the foxes and their abortion fortus organs of main fox farms. Among the strains, 26 strains were isolated from the abortion foetus organs, isolation rate was 92.86%; 118 strains were isolated from the vaginal exeretion of the abortion and empty foxes, isolation rate was 34.01%; 1 strain was isolated from inguinal lymph node of the pelted positive fox, isolation rate was 2%. None was isolated from blood. By causative agent isolation, we revealed the bacterium survival position in vivo, and the best isolation route isolation opportunity and isolation methods were selected. By artificial infection test, we have proved pathogenicity of the bacterium.
