Catheter-Related Bloodstream Infection with Rhizobium radiobacter and Pseudomonas oryzihabitans Co-Infection: A Case Report and Literature Review
Abstract
Background: Catheter-related bloodstream infections (CRBSIs) caused by environmental organisms are uncommon, and polymicrobial cases are even rarer. Methods: We describe the first case of catheter-related bloodstream infection caused by two infrequent environmental organisms-Rhizobium radiobacter and Pseudomonas oryzihabitans-occurring as a co-infection. Results: The patient's occupation involved frequent exposure to moist, soil-contaminated environments. Although these bacteria are often considered contaminants, they are capable of causing invasive infections such as bacteremia, which can be life-threatening. Conclusions: This case underscores the emerging pathogenic potential of R. radiobacter and P. oryzihabitans co-infection, particularly in patients with underlying malignancies or end-stage renal disease who have indwelling vascular devices, and highlights the importance of considering occupational and environmental exposures in the differential diagnosis of unusual pathogens.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
