Core Tip

Core Tip: Leclercia adecarboxylata (L. adecarboxylata) is a ubiquitous microorganism often found in water and soil and a rare pathogen can be isolated from specimens such as blood. We present a rare case of infective endocarditis caused by L. adecarboxylata that occurred in an immunocompetent male patient. He presented with clinical symptoms after diarrhoea. L. adecarboxylata was identified to be the only pathogen and the intestine may be the portal of entry for the infection. Immunosuppression is a significant risk factor for L. adecarboxylata infection. L. adecarboxylata is usually the only pathogen cultured in immunosuppressed individuals. Bacteria crossing the intestinal mucosal barrier may cause bacteremia.
