Cupriavidus gilardii Pneumonia in a Young Patient with Chronic Kidney Disease: A Case Report

Cupriavidus gilardii (C. gilardii) is a Gram-negative, motile, non sporulating, non lactose fermenting bacterium. It was first identified by Coenye et al., and has a complex taxonomy, often being misidentified as Wausteria gilardii, Ralstonia gilardii. It is commonly found in ecosystems containing plants and heavy metal-contaminated soil and is rarely isolated from clinical samples with no clear evidence of its clinical significance. The pathogenic nature of C. gilardii in respiratory ailments, particularly in patients with cystic fibrosis, is still unclear. This case report presents a 19-year-old female with Chronic Kidney Disease (CKD) who developed pneumonia caused by C. gilardii. The report also includes the sensitivity pattern of the bacterium to guide physicians in treating these rare pathogens.
