Key result
Serratia marcescens arthritis demonstrates both positive and negative birefringent crystals in inflammatory synovial fluid.
Why the study?
Arthritis caused by Serratia marcescens with both positive and negative birefringent crystals in the same synovial fluid is an unusual clinical presentation requiring further characterization.
Case Report (n=1)
Highlights the need to consider multiple pathological processes occurring in the same joint, particularly in men over 40 with predisposing illnesses or on immunosuppressive drugs.
Alerts clinicians to possible concurrent septic and crystal arthritis; leaves open the prevalence of mixed crystal types in infected joints.
We encountered an unusual case of arthritis caused by Serratia marcescens, with both positive and negative birefringent crystals in the same inflammatory synovial fluid. This combination of events is most likely to occur in men over 40 years old who have a predisposing illness or are receiving immunosuppressive drugs. This case shows the need to consider multiple pathological processes occurring in the same joint.

James W. Mayer (1976) conducted a case report in Arthritis caused by Serratia marcescens (n=1). Serratia marcescens infection was evaluated. A case of arthritis caused by Serratia marcescens demonstrated both positive and negative birefringent crystals in the same inflammatory synovial fluid.
