Clinical and environmental investigation of six cases of Chryseobacterium arthrosphaerae infections in a Southern Italian hospital.

ABSTRACT: Chryseobacterium spp. are Gram-negative, opportunistic pathogens antibiotic-resistant commonly found in the environment. The aim of this study was to investigate potential sources of Chryseobacterium infections in healthcare settings by comparing clinical and environmental isolates using phenotypic and genotypic analyses. Between June and July 2023, six cases of infection with Chryseobacterium spp. were identified in a hospital in Apulia, southern Italy. Environmental sampling (air, surfaces and water) was performed in parallel with routine clinical investigations. Isolates were subjected to antibiotic susceptibility testing and genotypic analysis using Sanger and Next-Generation Sequencing. Five cases of Chryseobacterium spp. infection were recorded in the Gastroenterology Department (Pav
