Both the isolates had similar virulence and antibiotic resistance genes; however, owing to the few structural changes, a slightly lower number of virulence genes were observed. Together, they shared 99.8% of the proteomes, and most variants identified spanned either hypothetical proteins or un-annotated regions.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Conclusions.<\/jats:bold> Based on comprehensive genome analysis the two strains were genetically similar, with a few structural variants, implying the second episode to be a relapse rather than a re-infection. There was no difference in the antibiotic resistance or virulence genes that may have explained the relapse.<\/jats:p>","DOI":"10.1099\/jmm.0.002003","type":"journal-article","created":{"date-parts":[[2025,4,15]],"date-time":"2025-04-15T15:16:44Z","timestamp":1744730204000},"source":"Crossref","is-referenced-by-count":0,"title":["Comparative
