Ralstonia mannitolilytica as a rare cause of spondylodiscitis following endoscopic lumbar discectomy- A report of two cases.

Ralstonia mannitolilytica is a low-virulence, gram-negative bacillus which causes opportunistic infections in immunosuppressed patients. Postoperative spondylodiscitis by R. mannitolilytica has not been reported so far. We report the management of two cases of postoperative spondylodiscitis caused by Ralstonia mannitolilytica presenting to our center within a span of one month following endoscopic lumbar discectomy at a different center. They were managed successfully by surgical debridement and appropriate antibiotics. In these two cases of R.mannitolilytica spondylodiscitis, prompt detection, and intensive treatment resulted in satisfactory outcomes in terms of fulfilling the purpose of the original surgery.
