EX54 - High Genetic Relatedness Between Historical and Contemporary Multidrug Resistant Bacteria Associated with Ukraine

The Russian invasion of Ukraine has placed extraordinary pressure on Ukrainian hospitals. One consequence of this has been the alarming increase in infections caused by multi-drug resistant organisms (MDROs), both within Ukraine and among the Ukrainian diaspora. The original source of these MDROs remains obscure and is the source of much speculation. In this study, we analyzed a collection of Acinetobacter baumannii and Pseudomonas aeruginosa collected before and after the invasion to glean a greater understanding of their relationship and origins.
