EXPERIMENTAL INFECTION OF FIVE SPECIES OF RAPTORS AND OF HOODED CROWS WITH FRANCISELLA TULARENSIS BIOVAR PALAEARCTICA

摘要: Sixteen raptors and three hooded crows were infected experimentally with Francisella tularensis biovar palaearctica. The birds parenterally or per os. One goshawk, one sparrow hawk crow died during the experimental period, remaining 16 killed 14–77 days after first infection. was not isolated from any bird. Antibody levels against F. measured in nine varied 0 to 1:1,280. In goshawk a titer of 1:1,280, positive fluorescent antibody reactions seen liver spleen. These results are similar those found by other authors indicating that corvids normally resistant infections tularensis.
