Infections caused by these microorganisms are exceptional. Improvement of microbiologist techniques in the last years has enabled their detection and more accurate knowledge. We present the case of an 11-year-old boy with mitochondrial disease with a longterm central catheter who suffered from two sepsis caused by L. adecarboxylata and R. ornithinolytica, respectively. In catheter-related infections, sometimes it is possible to provide antimicrobial treatment without removal of catheter with good results, as in our patient. It is important to recognize L. adecarboxylata and R. ornithinolytica like increasingly frequent pathogenic bacteria, mostly in immunocompromised or chronic patients.esCatheter-related infectionsEnterobacteriaceaeMitochondrial diseasesPediatricsSepsisAnti-Bacterial AgentsCatheter-Related InfectionsChildEnterobacteriaceaeEnterobacteriaceae InfectionsHumansMaleMitochondrial DiseasesSepsisresearch article30869494open access10.5546/aap.2019.e1471668-3501https://doi.org/10.5546/aap.2019.e147
