Abstract:

Ralstonia mannitolilytica is an emerging human pathogen, which is an environmental bacterium. Hospital outbreaks are limited; however, the organism has been reported from tumour patients, bloodstream infections, recurrent meningitis patients, etc. In this report, we discuss a case of septicemia caused by R. mannitolilytica and its antibiotic susceptibility in a patient with pulmonary oedema. A 96-year-old female patient presented to the hospital with breathlessness, palpitations and chest pain. Ralstonia mannitolilytica has been isolated from blood culture using conventional techniques and the diagnosis was confirmed with automated VITEK 2 compact. To the best of our knowledge, this is the first case of Ralstonia mannitolilytica reported in a cardiac patient with septicaemia in Chennai. Rapid identification of this bacteria and appropriate use of antibiotics would help in minimising the emergence of drug resistance.
