Pasteurella anatisalso Gallibacterium anatis is a Gram-negativenonmotile, penicillin -sensitive coccobacillus belonging to the Pasteurellaceae family. The number of different techniques and antimicrobial agents made it difficult to compare previous results.

They might also be used directly for identification, or result in subsequent development of polymerase chain reaction assays targeting specific regions of the aforementioned genes.
