When identified, they are associated with immunocompromised adults, often causing bacteraemia. Due to their rarity, members of this genus can be overlooked or misidentified using automated laboratory identification systems. We report on an immunocompetent adolescent patient who developed septic arthritis due to Roseomonas gilardii following surgery for a sports injury. The isolate was initially misidentified as Bordetella bronchiseptica using the Vitek 2 system, but confirmed as R. gilardii based on 16S rRNA gene sequencing. To the best of our knowledge, this is the first case of a healthy paediatric patient with septic arthritis due to R. gilardii. %U https://www.microbiologyresearch.org/content/journal/jmm/10.1099/jmm.0.011106-0
