Sepsis caused by Myroides spp. associated with bronchopneumonia and coinfection with Pseudomonas aeruginosa and Proteus vulgaris: A case report and review of Myroides spp. infections

Victoria Birlutiu, Rares Mircea Birlutiu

Background: Myroides spp. is considered an opportunistic germ, possibly pathogenic in immunocompromised patients, in whom it may cause varied clinical pictures in terms of severity, from skin and soft tissue infections, fasciitis, to urinary or respiratory infections, central nervous system infections, endocarditis etc. Few cases of sepsis caused by Myroides spp. have been described.

Case presentation: We present the case of an immunocompromised patient with diabetes mellitus, chronic renal failure, diagnosed with sepsis caused by Myroides spp. with a chronic leg ulcer as starting point, superinfected with Pseudomonas aeruginosa and Proteus vulgaris, and associating bronchopneumonia.

Conclusion: The presence of Myroides spp. or of other opportunistic pathogens in an immunocompromised patient, especially in those with renal failure, diabetes and persistent skin lesions, should be considered in cases with lack of response to commonly recommended antibiotics in these situations, as a possible emergence of an opportunistic pathogen that creates difficulties for treatment.
