We report a case of severe pneumonia due to Chryseobacterium indologenes in an immunocompetent patient. Chryseobacterium indologenes (formerly Flavobacterium indologenes) are saprophytic Gram-negative rods widely distributed in damp environment. Many sites of infection were described in the literature. These infections are always severe sometimes associated to multiple organ failure. The evolution is usually favorable with antibiotic treatment. Bacteria characteristically grow as yellow-pigmented colonies. They are naturally resistant to many antimicrobial agents. They are usually susceptible to piperacillin(DCI) alone or combined with tazobactam(DCI), ceftazidime(DCI), cefepime(DCI), fluoroquinolones(DCI), rifampin(DCI) and cotrimoxazole(DCI), but the in vitro susceptibility to these antibiotics should be systematically tested. Nevertheless, the optimum antibiotic treatment for Chryseobacterium-related infections remains to be established. In the case we report, the diagnosis was made according to the results of bronchial sample bacterial culture. This case report underlines the need for specific management of patients infected with this species.
