Abstract
Sphingomonas paucimobilis, is a yellow-pigmented, aerobic, non-fermentative, gram negative motile bacillus. S. paucimobilis which is widely found in nature and hospital environments rarely cause serious or life threatening infections. It’s rarely isolated from clinical specimens but it is associated with a great variety of infections in both healthy and immunocompromised people. In this report we present two cases with infection due to S. paucimobilis. One of them was systemic blood stream infection and one focal infection. One was immunocompetent and the other with diabetes mellitus for more than ten years. Both of them were community acquired infection due S. Paucimibilis. These cases are reported to emphasize that S. paucimobilis should be kept in mind as a community acquired infection. We present the first cases of Sphingomonas paucimobilis in Albania one of which is a spondylodiscitis in immunocompetent patient and include updated literature concerning infections by this microorganism.
Highlights
Sphyngomonas paucimobilis is a gram-negative, slightly motile with polar flagellum and non-spore-forming, non-fermentative; oxidase positive and forms yellow-pigmented S colony in blood agar, opportunistic pathogen that rarely causes infections in humans [1,2]
The bacteria is widely found in natural environment, especially in water and soil, but it have been isolated from hospital water supplies, respirators, stocked distilled water, blood, wounds, hospital dialysis equipment, patients with meningitis, septicemia, bacteremia, peritonitis, wound infections, soil, river water, deep subsurface sediments, corroding copper pipes, drinking water, rhizosphere and surfaces of plants [5-7,11]
Since 1977 it has been reported to cause variety of diseases from various parts of the world. This organism is responsible for two types of infection in humans: sporadic or community-acquired infections, probably of endogenous or environmental origin; and nosocomial infections associated with the contamination of sterile fluids employed in hospitals [15]
Summary
Sphyngomonas paucimobilis is a gram-negative, slightly motile with polar flagellum and non-spore-forming, non-fermentative; oxidase positive and forms yellow-pigmented S colony in blood agar, opportunistic pathogen that rarely causes infections in humans [1,2]. A 54-year-old female patient operated 4 years before with aortic valve stenosis, with mechanic valve, presented in emergence service with intermittent fever for 3 days, chills, altered mental status, and malaise She had been suffering from diabetes mellitus for more than 10 years, medicated with oral drugs. After therapy was evidenced clinical improvement of the patient in sense of: significantly reduction of pain, improved mobility, reduction of inflammatory parameters and slightly improved imaging framework. He became outpatient and continued orally therapy for another 4 weeks with ciprofloxacin and trimethoprim/sulphamethoxazole. We followed him for more than 4 months and he was recovered (Figure 1)
