A Extensively Drug-resistant Pseudomonas Putida Bacteremia That Was Resolved Spontaneously

Abstract

Pseudomonas putida (P. putida) is a rare pathogen that causes various infections in newborns, neutropenic and cancer patients, or in patients with risk factors leading to immunosuppresion. Antibiotic resistance in P. putida is seen in growing numbers. Although it is less virulent compared to Pseudomonas aeruginosa, mortal infections are reported. Here, a P. putida case after an invasive procedure in a patient with gastrointestinal malignancy is reported. Although, it caused an antibiotic resistant bacteremia, it resolved spontaneously without any treatment. P. Putida might have lower virulence and a different antibiotic susceptibility when compared to Pseudomonas aeruginosa in different cases. More clinical information is needed for further evaluation.
