A rare bacteremia caused by Cedecea davisae in patient with chronic renal disease

PATIENT Female, 77. FINAL DIAGNOSIS Bacteremia. SYMPTOMS Chills • diarrhea • fever • nausea. MEDICATION - CLINICAL PROCEDURE X-Ray • CBC • urine and blood cultur. SPECIALTY Infectious diseases. OBJECTIVE Rare disease. BACKGROUND Cedecea davisae is a gram negative, oxidase negative bacilli that include 5 species. In the medical literature there are very few reports that describe infections caused by different species of the Cedecea genus. CASE REPORT In this paper we report a fourth case of bacteremia in a 77 year-old patient with a chronic renal disease that was successfully treated with ceftazidim and ciprofloxacin. Additionally, we present a review of all the reported infections that were caused by C. davisae. CONCLUSIONS Five cases (not including our report) of Cedecea bacteremia were reported so far. Cedecea infections and particularly C. davisae infections can be difficult to treat due to the antibiotic resistance of the bacterium. Therefore we propose to consider treating C. davisae bacteremia with a combined antibiotic treatment until getting laboratory results for antibiotic-sensitivity tests.
