Abstract
Chrysobacterium gleum is a nonmotile, oxidase positive, non-fermentative un-sporulate Gram-negative bacillus, bacteria belonging to the genus Chrysobacterium. Infections caused by Chrysobacterium spp are usually health care associated and the most frequent in immunocompromised patients and neonates.In this report we present a case of a 35-year-old female patient admitted to the hospital for extreme malnutrition and a hepatic le-sion. Chrysobacterium gleum was isolated from tracheal aspirate and blood culture. The strain was identified with Microflex MALDI Biotyper (Bruker Daltonik, Fre-mont, CA). The patient was successfully treated with piperacillin/tazobactam. Em-pirical therapy is difficult due to intrinsic resistance to most antimicrobials which are usually effective against Gram-negative bacteria.
Highlights
In 1994, it was assigned to a new genus Chrysobacterium, belonging to the family Flavobacteriaceae

In this report we have presented a patient with extreme malnutrition and a hepatic lesion
Summary
It comprised yellow pigmented, asporogenic Gram-negative bacilli. (1) C. gleum is rarely reported in the literature; it is predominantly isolated from various clinical specimens (urine, sputum, wound swab, vaginal swab). In previous reports it was not separated from other species in the genus Chrysobacterium due to insuficient identification or misidentification. Laboratory results showed the recovery of white blood cells and the decrease of inflammatory parameters.On the 28th day in the ICU the development of pulmonary infiltrates was noticed as well as elevated temperature. (4) The transferability of meropenem resistance was tested by conjugation (broth mating method) according to Elwell and Falkow using Escherichia coli A15R-resistant to rifampicin as recipient strain (5). PCR was performed to detect blaMBL genes (blaVIM, blaIMP, blaGIM, blaSPM) (6), but yielded no PCR products and carbapenem resistance is likely to be atributted to the chromosomal metalo-βlactamase of the genus Chrysobacterium
