摘要
The present study investigated 15 dead cases of captive wild goslings(Anser anser),which were bred in a small poultry farm in Shandong Province,China.The examined cases presented diverse clinical signs accompanied with neurological manifestations and fatal outcomes.Bacterial culture identified the gram-negative Neisseria sp.from the brain homogenate of most examined cases(10/15,66.7%).The isolated bacteria were identified based on morphologic characteristics,biochemical tests and 16S rDNA typing.Results proved that 1 identical bacterial strain(BNO09-3)was isolated from the positive cases.The phylogeny based on the 16S rDNA gene sequences indicated that this isolate has a close relationship with various strains of genus Neisseria sp.isolated from liver and feces of duck.This is the first report of Neisseria sp.causing fatality in captive wild geese in China.
