The Deteetion Process of a Strain of Citrobacter Amalonaticus Carrying Common Antigens with Shigella

Objectives  To provide a reference for the identification of enteric bacteria in future works.

Method  All procedures followed the methods in GB/T4789.5-2012 for morphological observation, staining of microscopic examination, serum agglutination test and systemic biochemical reaction.

Results  A strain of citrobacter amalonaticus with a colonial morphology similar to shigella on SS and HE flat plate was detected, and it created a strong agglutination reaction with shigella flexneri tested by a four-type polyvalent serum, including subtype serum of shigella dysenteriae and bao shi shigella.

Conclusion  Citrobacter amalonaticus and shigella have some common antigens.
