Abstract: The phylogenetic analysis and biological characterization of one bacterial strain isolated from eggs was identified, based on the gram-negative bacterial biochemical identification system (cultural character and chemical properties), 16S rDNA gene sequence analysis and the other classical methods. The results showed that the isolate was Morganella morganii. Drug sensitive test showed that the isolate was resistance to furoxone, rifampicin, tetracycline, fosfomycin, polymyxin B and azithromycin. The sequence analysis indicated the isolate was highly homolgous with other foodborne Morganella morganii isolates.

Key words: Morganella morganii; isolation and identification; eggs; genetic evolution analysis
