      Acinetobacter baumannii is a nosocomial pathogen that poses a serious threat due to the rise of incidence of multidrug-resistant (MDR) strains. During the COVID-19 pandemic, MDR A. baumannii clones have caused several outbreaks worldwide. Here, we describe a detailed investigation of an MDR A. baumannii outbreak that occurred at Policlinico San Matteo (Pavia, Italy). A total of 96 A. baumannii ...

      Background One Health approaches to address the increasing threat of antimicrobial resistance (AMR) are gaining attention. However, data on the distribution and movement of bacteria and their AMR-associated genes between clinical and non-clinical sources are scarce, especially from low-income and middle-income countries. We aimed to analyse Klebsiella isolates from various sources in Ghana and ...
