Abstract

Ralstonia mannitolilytica is a waterborne bacteria found in moist environments. Even though R. mannitolilytica is with low virulence, it is found to be a potential pathogen in hospital settings in recent times. The ability of Ralstonia spp to survive the commonly used methods of sterilization is the main reason for infections caused by them. Hence, the infections are seen especially in patients with invasive devices such as central venous catheters (CVCs) and are always invasive in nature like bacteremia, pneumonia meningitis, etc. We report an outbreak of R. mannitolilytica catheter related blood stream infections (CRBSI) in an oncotherapy ward. A total of 18 confirmed cases were detected using Vitek-2 and MALDI TOF MS. Pulsed field gel electrophoresis (PFGE) was used to determine the clonality of the strains. Antibiotic sensitivity and resistance pattern in R. mannitolilytica is also discussed.
