ABSTRACT
Introduction-Serratia marcescens is a gram negative bacilli which was not recognised as a pathogen until the 1960’s. It has been observed to be increasingly associated with nosocomial and opportunistic infections. This case report highlights the increased predisposition of a diabetic patient to Serratia infection while hospitalisation.
Case History- A 56 year old, female patient with a history of Diabetes mellitus type II for the past 20 years was admitted to a tertiary care hospital with the complaints of wound on the dorsum of the right foot along with discharge of pus, redness of the foot and decreased mobility for 10 days. Pathological and biochemistry examination of the blood was done along with collection of two pus swabs were collected and processed by standard microbiological procedures to identify the bacterial isolate to be Serratia marcescens. Antimicrobial susceptibility testing was performed and the multidrug resistant isolate was found to be susceptible to carbapenems. Patient was successfully treated using imipenem intravascular infusion.
Conclusion- In conclusion, infections in immunocompromised patients with underlying chronic co-morbidities with history of hospitalization must be diagnosed with high index of suspicion of Serratia owing to its underlying characteristic of non-pigment production in pathogenic hospital acquired strains. Owing to the multidrug resistance and intrinsic AmpC production of Serratia, such infections must be promptly recognised and appropriately treated based on multidisciplinary treatment approach aiming at a good patient outcome.
