Outbreak Analysis Using 1928 - Acinetobacter baumannii
The tree is created using UPGMA and distances shown are computed based on pairwise allelic differences (hamming distance). Missing genes are not included in the count.
1928's analysis of an outbreak: Acinetobacter baumannii
The ambition with 1928’s outbreak analyses is to reproduce results from scientific studies and highlight the quality of the results generated by the 1928 platform.
In order to demonstrate the accuracy of outbreak analysis with the 1928 platform, a phylogenetic tree is created from an outbreak of Acinetobacter baumannii. The tree shown in the figure above is generated using the 1928 analysis platform.
In this analysis, 1928 reproduces results from the scientific paper Utility of Whole-Genome Sequencing in Characterizing Acinetobacter Epidemiology and Analyzing Hospital Outbreaks (pmid: 26699703) by Margaret A. Fitzpatrick, Egon A. Ozer, Alan R. Hauser.
The 1928 Acinetobacter baumannii cgMLST schema is created from 124 reference genomes giving the scheme 2308 core genes. All genes included in the schema are present in at least 95% of reference genomes.
