SOLOAGA, Rolando et al. Catheter-related bloodstream infection by Ralstonia mannitolilytica. Acta bioquím. clín. latinoam. [online]. 2011, vol.45, n.1, pp. 109-112. ISSN 0325-2957.
Ralstonia mannitolilytica is a glucose non-fermentative, aerobic gram-negative bacillus formerly known as Ralstonia picketti biovar3/"thomasii" of relatively low virulence. It has been isolated from a wide kind of infections like bacteremia, meningitis, endocarditis, osteomielitis and from the respiratory tract of patients with cystic fibrosis. The case presented is related to a 26-year-old male patient with diabetes insipidus, hypothyroidism and histiocytosis X with a two-day-febrile syndrome and chills associated with the presence of a porthacat catheter used for administrating medication. An episode of catheter-related bloodstream infection was documented by using Bact-Alert blood culture system and differential-time-to-positivity method for central venous catheter versus peripheral blood cultures (>120min). Once removed, it was confirmed through Maki semiquantitative technique (>15 ufc). The microorganism was identified by API 20 NE, Vitek 2C and Vitek 1 as. Ralstonia mannitolilytica.
