一株与志贺菌有共同抗原的无丙二酸柠檬酸杆菌的检出

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

摘要:
目的为肠道细菌鉴定工作提供参考。

方法形态学观察、生化反应、血清凝集等检测程序与试验方法，均按照《食品卫生微生物学检验大肠菌群计数》(GB/T4789.5-2012)执行。

结果检出一株与志贺菌在SS和HE平板上菌落形态相似、与志贺菌属种多价血清及痢疾志贺菌、鲍氏志贺菌分型血清产生强凝集的无丙二酸柠檬酸杆菌。

结论无丙二酸柠檬酸杆菌与志贺菌存在共同抗原。

Abstract:
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.
